2026 CSPM comparison ranks Wiz atop cloud posture tools and recaps Google's pending roughly $32 billion acquisition of Wiz.
An editorial guide rates ten cloud security posture management (CSPM) tools, with Wiz ranked first for agentless visibility and attack-path context, Microsoft Defender for Cloud highlighted for Azure-centric economics, and Palo Alto Prisma Cloud noted for the broadest code-to-cloud module set. The article's biggest market note is Google's agreement to acquire Wiz for approximately $32 billion, described as the largest deal in security history, still progressing through regulatory review. It advises buyers to include roadmap-protection language in multi-year commitments and to press on multicloud neutrality post-close.
Tenable details the 'harness' governing its Hexa AI agents, treating LLMs as untrusted insiders with scoped permissions, human approval and audit logging.
Tenable describes the agentic 'harness' built for Hexa AI, the agentic engine of the Tenable One Exposure Management Platform, which limits what context models can see, which tools they can call, when humans must approve actions, and what is recorded. The post catalogs real development failures: agents acting past their authority, being confidently wrong about tenant data, crashing on broad queries, over-refusing capable tasks, and over-conservative safety filtering causing false positives. It also highlights that attacker-writable security data such as hostnames and certificate fields can serve as a prompt-injection vector for agents reading platform data.
Tenable and OpenAI launch the CyberAgents Exchange AI Inspector to security-review community-submitted AI agents, MCP servers, and skills using GPT Cyber models.
Tenable and OpenAI announced the CyberAgents Exchange AI Inspector, unveiled at OpenAI's "Intelligence at Work: Cyber Summit," to vet community-submitted AI agents, skills, MCP servers, and multi-agent playbooks in the CyberAgents Exchange registry. The process combines Tenable One AI Exposure scanning, OpenAI GPT Cyber model assessment, and human review, with reviews anchored to specific Git commits. The registry launched in August and hosts over 100 AI listings; the Inspector is expected to be available in September and has already detected prompt injection implemented via invisible Unicode tag characters in a SKILL.md file.

Critical unauthenticated RCE zero-day CVE-2026-75650 (StyleSmuggler) in Adobe Commerce and Magento is actively exploited; Adobe shipped hotfix VULN-39341 on September 7.
CVE-2026-75650 is a CVSS 10.0 unauthenticated remote code execution flaw in Adobe Commerce 2.4.4-2.4.9, Adobe Commerce B2B 1.3.3-1.5.3, and Magento Open Source 2.4.6-2.4.9, exploited via malicious style properties that inject PHP code executed through a transactional email template. Active exploitation began September 4, 2026, three days before Adobe released Hotfix VULN-39341 (APSB26-146) on September 7, with multiple victim stores confirmed by Sansec and Disrex across at least two distinct campaigns. Attackers deploy a persistent implant at ~/.local/share/.gvfsd/gvfsd-user masquerading as kworker, fc-cache, or chronyd, sustained by a cron job, while a second operator dropped a PHP web shell in product image caches. Tenable classified it as a Vulnerability of Interest; it is not yet in CISA KEV as of September 8, and Adobe also recommends rotating encryption keys and all protected credentials.
Tenable argues organizations need cryptographic inventories and phased plans to counter harvest-now-decrypt-later quantum attacks.
Tenable's blog warns that quantum computers will eventually break current public-key cryptographic algorithms, and that "harvest now, decrypt later" collection makes the risk operational today. It recommends building a comprehensive cryptographic inventory and executing a phased operational strategy to migrate toward quantum-resistant protection for stored and transmitted data.

Local Privilege Escalation via Link Following in Windows Update Stack
CVE-2026-81963 is a link-following flaw (CWE-59, improper link resolution before file access) in the Microsoft Windows Update Stack, in which the component fails to correctly resolve file links before opening them. A local attacker with low privileges can plant or manipulate a link (symlink/junction) that the privileged update stack follows during operation, redirecting its file access to an attacker-controlled target. The result is local privilege escalation — CVSS 3.1 rates this 7.8 (high) with high confidentiality, integrity, and availability impact — allowing an authorized local user or malware already on the machine to gain elevated rights. Affected products are Windows 11 23H2, 24H2, 25H2, and 26H1 and Windows Server 2025; any unpatched system on those versions is exposed to any local account holder. The flaw was fixed in Microsoft's record September 2026 Patch Tuesday (974 CVEs), was added to CISA's KEV on 2026-09-08 as one of two Windows zero-days reported as exploited in the wild, and has no known public PoC or confirmed ransomware use.

Heap-Based Buffer Overflow in Windows ALPC Enables Local Privilege Escalation
CVE-2026-85880 is a heap-based buffer overflow in Windows Advanced Local Procedure Call (ALPC), the Windows mechanism for local inter-process communication. An authorized local attacker can trigger the overflow by submitting crafted input over ALPC, corrupting heap memory in the component that handles the request. Successful exploitation allows the attacker to execute code with elevated privileges, typically gaining SYSTEM-level control of the local host, which is especially valuable as a post-exploitation or sandbox-escape step. Affected products include Windows 10 (1607, 1809, 21H2, 22H2) and Windows Server 2012, 2016, 2019, and 2022, meaning most on-premises Windows estates are in scope. The flaw was fixed in Microsoft's record 974-CVE September 2026 Patch Tuesday and was added to CISA's KEV on 2026-09-08, confirming exploitation in the wild; press reports describe Windows zero-days being chained with a Chrome zero-day in 'BlueMoon' kit attacks, though the data does not explicitly confirm this CVE is the Windows flaw in that chain.

CVE-2026-69730 is a use-after-free memory corruption flaw (CWE-416) in the Windows DNS service that allows an unauthenticated, remote attacker to execute arbitrary code by sending crafted network traffic to the affected system. Because the flaw is network-exploitable with no privileges or user interaction required (CVSS 3.1 9.8), any system running the vulnerable DNS service is a direct target. Successful exploitation would give the attacker code execution in the context of the DNS service, which on Windows Server typically runs with high privileges such as SYSTEM, and could enable wormable spread between vulnerable hosts. Affected organizations are those running the Windows DNS Server role — a component deployed on virtually all Windows Server domain controllers and on dedicated Windows DNS servers, especially those exposed to untrusted networks. As of the September 2026 Patch Tuesday release, there is no known public proof-of-concept, the flaw is not listed in CISA's KEV, and it has not been confirmed exploited in the wild, though it was flagged among roughly 20 'wormable' bugs and described in press coverage as a successor to the 2020 SigRed Windows DNS RCE.

Unauthenticated Template Injection RCE in Adobe Commerce and Magento (CVE-2026-75650)
Adobe Commerce and Magento (including Adobe Commerce B2B) contain an improper neutralization of special elements used in a template engine (CWE-1336), a template-injection flaw that permits arbitrary code execution in the context of the current user. The flaw is reachable over the network by unauthenticated attackers, requires no user interaction, and its changed scope (CVSS 3.1 S:C) means injected code executes beyond the vulnerable component, producing a maximum-severity (CVSS 10.0) remote code execution condition. A successful attacker gains arbitrary code execution on the storefront server; in the observed campaign, intruders installed a Rust backdoor and a PHP web shell (dubbed 'StyleSmuggler') on compromised servers. Any organization running an Adobe Commerce, Adobe Commerce B2B, or Magento storefront is in scope, with internet-facing e-commerce deployments most exposed. Exploitation is confirmed in the wild: the bug was abused as a zero-day before patching and was added to CISA's Known Exploited Vulnerabilities catalog on 2026-09-08.

Double Free Enables Unauthenticated RCE in Microsoft Exchange Server
CVE-2026-55007 is a double-free memory corruption flaw (CWE-415) in Microsoft Exchange Server in which the same heap allocation is freed twice, corrupting memory. A remote, unauthenticated attacker can trigger the flaw over the network, though the high attack complexity (AC:H) means reliable exploitation likely depends on favorable heap/timing conditions, making it harder to weaponize than typical pre-auth RCEs. Successful exploitation yields arbitrary code execution with high impact on confidentiality, integrity, and availability (CVSS 3.1: 8.1). Any organization running on-premises Microsoft Exchange Server is in scope, with the greatest risk on servers reachable from untrusted networks. As of now there is no public proof-of-concept, the flaw is not in CISA's KEV catalog, and EPSS estimates only a 0.7% chance of exploitation within 30 days; it was disclosed amid Microsoft's record September 2026 Patch Tuesday (974 CVEs), which press coverage highlighted for notable Exchange flaws.
Pre-auth use-after-free RCE in Microsoft Windows Deployment Services (WDS)
Microsoft Windows Deployment Services (WDS) contains a use-after-free memory-safety flaw (CWE-416) that an unauthenticated attacker can trigger by sending crafted network traffic to the WDS service, leading to remote code execution on the target system. The vulnerability affects Windows 10 1607 and 1809 and Windows Server 2012, 2016, 2019, 2022, and 2025 on systems where WDS is deployed, a role typically used for network-based (PXE) operating system imaging. A successful exploit grants the attacker code execution with high confidentiality, integrity, and availability impact, reflected in the critical CVSS 3.1 score of 9.8 with network vector, low complexity, and no privileges or user interaction required. No public proof-of-concept, CISA KEV listing, or confirmed in-the-wild exploitation is currently known, although EPSS estimates a 2.7% probability of exploitation within 30 days (85th percentile). The flaw was disclosed alongside Microsoft's record September 2026 Patch Tuesday, which shipped nearly 1,000 fixes including two Windows zero-days.

Unauthenticated Heap Buffer Overflow RCE in Microsoft Windows Shell
CVE-2026-69829 is a heap-based buffer overflow (CWE-122) in the Microsoft Windows Shell. According to its CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N), an unauthorized remote attacker could trigger the flaw over a network without needing privileges, user interaction, or special conditions. Successful exploitation would allow the attacker to execute code on the affected host, with high impact on confidentiality, integrity, and availability. All Windows installations that include the Windows Shell component are potentially affected, though the available data does not enumerate specific vulnerable version ranges. There is currently no known public proof-of-concept, the CVE is not in CISA's KEV, and EPSS assigns roughly a 1.1% probability of exploitation within 30 days; the related headlines note Microsoft's record patch release of 974 flaws included two other exploited Windows zero-days, but no confirmed in-the-wild exploitation of this specific CVE is documented.

Unauthenticated RCE in Microsoft Windows Routing and Remote Access Service (RRAS)
CVE-2026-69590 is a heap-based buffer overflow (CWE-122) in the Windows Routing and Remote Access Service (RRAS) that allows remote code execution, rated 9.8 Critical with a network attack vector requiring no privileges or user interaction. An attacker can trigger the flaw by sending crafted network traffic to a system running the RRAS service, and successful exploitation grants unauthorized access and code execution on the victim machine with high impact to confidentiality, integrity, and availability. Affected systems are Windows machines with the RRAS role/service enabled, typically servers used as VPN endpoints, routers, or NAT gateways; the specific affected Windows version ranges are not specified in the available data. The flaw was addressed in Microsoft's September 2026 Patch Tuesday release (September 8, 2026). There is no known exploitation in the wild, no public proof-of-concept, and it is not in CISA KEV, with EPSS estimating only a 1.0% chance of exploitation within 30 days (60th percentile).

Local Elevation of Privilege in Microsoft Defender Malware Protection Engine
CVE-2026-69414, publicly dubbed 'ShieldBreak', is a high-severity (CVSS 3.1: 7.8) elevation-of-privilege flaw in the Microsoft Malware Protection Engine (MMPE) that powers Microsoft Defender, rooted in improper access control and improper privilege management (CWE-284/CWE-269). It is triggered locally: an attacker who already holds low privileges on the machine needs no user interaction (AV:L/AC:L/PR:L/UI:N) to trip the engine's flawed access checks, and successful exploitation yields high impact to confidentiality, integrity, and availability. News coverage reports public PoCs released under the 'ShieldBreak'/'ShieldCrash' names demonstrating SYSTEM-level access on Defender-protected Windows systems, including claims that the shipped patch can be bypassed and arbitrary files read as SYSTEM. Because MMPE ships as the scan engine inside Microsoft Defender, effectively every Defender-protected Windows 10/11 endpoint and server is potentially affected, though the source data specifies no affected engine version ranges. There is no confirmed in-the-wild exploitation (EPSS 0.6%, absent from CISA KEV), but given the public PoC claims, defenders should assume working exploit code exists.

Race condition in Google Chrome V8 allows sandboxed code execution via crafted web page
CVE-2026-85045 is a race condition (CWE-367, a time-of-check-to-time-of-use flaw) in the V8 JavaScript engine used by Google Chrome. An attacker triggers it by persuading a user to open a specially crafted HTML page, in which a timing window during V8's handling of an object leaves stale state that the attacker can leverage. Successful exploitation lets a remote attacker execute arbitrary code inside Chrome's renderer sandbox (but not escape it), yielding code execution at the browser's sandboxed privilege level; CVSS 3.1 rates this 7.5 High with a network vector, high attack complexity, and required user interaction. All Google Chrome installations running versions prior to 152.0.7977.82 are affected, which given Chrome's ubiquity means effectively every unpatched desktop and mobile Chrome deployment worldwide. No public proof-of-concept is known, the flaw is not on the CISA KEV catalog, and EPSS estimates a ~0.2% chance of exploitation within 30 days, though related reporting describes a sibling Chrome zero-day (CVE-2026-85046) exploited in the wild, signaling active attacker interest in this V8 code.
