Perfect-10 GitLab bug under attack days after patch lands

CISA confirms active exploitation of CVSS 10.0 GitLab path traversal flaw CVE-2026-85706 days after patches shipped, enabling unauthenticated arbitrary file reads.

CISA added CVE-2026-85706, a maximum-severity 10.0 CVSS path traversal flaw in GitLab's repository commits API, to its Known Exploited Vulnerabilities catalog and confirmed active exploitation. The bug allows unauthenticated attackers to read arbitrary files, including configuration data and credentials, from self-managed GitLab CE/EE servers via a single HTTP POST request. GitLab shipped fixes on September 10 in versions 19.3.2, 19.2.6, and 19.1.8, covering versions 18.7 through 19.3. watchTowr is observing probes against internet-facing instances and warns widespread exploitation is likely to follow quickly.

More JFrog Artifactory bugs under attack, and all 3 have patches

Multiple attackers are exploiting three JFrog Artifactory CVEs, including critical auth-bypass CVE-2026-82329, to gain admin access and install backdoors.

Wiz confirmed in-the-wild exploitation of all three JFrog Artifactory vulnerabilities: CVE-2026-42018 (high, improper authentication token leak), CVE-2026-42016 (high, privilege escalation), and CVE-2026-82329 (critical, unauthenticated authentication bypass). Starting August 15, attackers chained the first two bugs against self-hosted instances to gain admin access and dropped a custom Rust backdoor for C2; from September 1-8 several attackers exploited CVE-2026-82329. Post-exploitation included persistent admin accounts, Groovy plugins for remote code execution, web shells, token minting, key theft, and reconnaissance. Patching velocity has been slow, with 49-62% of organizations still vulnerable to individual bugs weeks after fixes were released.

Novel Blue Moon kit targeting Chrome and Windows reflects new reality of AI-driven exploits

Proofpoint reports the BlueMoon exploit kit, chaining two Chrome V8 zero-days and a Windows ALPC bug, being shared across China-linked espionage groups.

Proofpoint identified a new exploit kit, BlueMoon, first observed on August 28 and used by TA412 (APT31/Violet Typhoon) against US NGOs, mining firms, and commodity trading companies. The kit chains a V8 type confusion RCE (CVE-2026-85046), a V8 sandbox escape, and a Windows Advanced Local Procedure Call privilege escalation (CVE-2026-85880), both patched flaws having been exploited in the wild. At least four espionage groups, most with suspected China nexus including UNK_LateNight, adopted the kit within days, targeting US aerospace firms with defense-sector lures. Fewer than 20 organizations were observed targeted, and researchers believe AI-assisted exploit development against upstream Chromium patches enabled the kit's rapid creation and sharing.

Chinese espionage groups swarm to exploit triple-link chain of zero-days

At least four China-aligned espionage groups chained three zero-days in Chromium browsers and Windows ALPC for espionage since late August.

Proofpoint observed at least four state-aligned threat groups, starting with TA412/Violet Typhoon/APT31 on August 28, chaining three zero-days in the 'BlueMoon' exploit chain targeting Chrome, Chromium-based browsers and Microsoft Windows. The chain includes RCE flaws in Chromium's JavaScript engine (CVE-2026-85046, CVE-2026-87491) and a Windows Advanced Local Procedure Call privilege-escalation zero-day (CVE-2026-85880), enabling sandbox code execution, sandbox escape and system privileges. APT31 delivered the chain via phishing links to NGOs, mining and commodity trading firms in the US, installing a browser extension disguised as Google Gemini to surveil activity and steal credentials. Other groups (UNK_LateNight, UNK_DoubleCheck, UNK_QuietRacket) targeted US aerospace, Vietnamese manufacturing, and Indonesian and Singaporean organizations; fewer than 20 victims were directly observed but the true count is likely higher.

4 groups caught using the same Chrome and Windows exploit kit

Proofpoint says at least four groups, some China-linked, actively share the BlueMoon kit chaining two Chromium and one Windows kernel exploit.

Proofpoint researchers report that at least four hacking groups, some with ties to the Chinese government, are actively using a nearly identical exploit kit named BlueMoon. The kit chains two Chromium browser vulnerabilities and one Windows kernel flaw affecting Windows 10, Windows 11 initial release, and a later Windows version to install malware of the attacker's choice. All three vulnerabilities received patches within the past 24 hours. Proofpoint attributes the kit's rapid, widely shared deployment to a Chromium patch-gap window and AI agents accelerating exploit development against publicly accessible upstream patches.

Chaotic Eclipse Released ShieldCrash, A PoC For Microsoft Defender Zero-Day

Researcher Chaotic Eclipse released ShieldCrash, a PoC showing Microsoft Defender's CVE-2026-69414 patch is incomplete, enabling arbitrary file reads as SYSTEM.

Security researcher Chaotic Eclipse published ShieldCrash, a proof-of-concept exploit for the Microsoft Malware Protection Engine privilege escalation vulnerability CVE-2026-69414 (ShieldBreak). The PoC performs arbitrary file reads with SYSTEM privileges on all supported Windows versions, including systems running the September 2026 security updates and Malware Protection Engine version 1.1.26080.3. The researcher claims Microsoft's patch fixed several exploit paths but missed a specific condition that still enables the attack. His recent releases also include zero-day PoCs targeting Nvidia, Kaspersky, Avast, and CrowdStrike Falcon.

Researcher Drops New Microsoft Defender PoC Showing ShieldBreak Patch Can Be Bypassed

Researcher Chaotic Eclipse released a PoC showing CVE-2026-69414's patch is bypassable, allowing arbitrary file reads as SYSTEM on current Windows.

The researcher known as Chaotic Eclipse published a proof-of-concept for a zero-day in Microsoft Defender, dubbed ShieldCrash, assessed as a patch bypass for ShieldBreak (CVE-2026-69414, CVSS 7.8). The PoC demonstrates an arbitrary file read as SYSTEM with the latest Windows installed, and all supported desktop versions are said to be impacted. Microsoft patched the original issue in Microsoft Malware Protection Engine 1.1.26080.3, which updates automatically. The same researcher recently released PoCs for flaws in CrowdStrike Falcon Sensor, Kaspersky, Avast Antivirus and NVIDIA.

Attackers exploit zero-days in consistently besieged SonicWall product

Two actively exploited SonicWall SMA 1000 zero-days chain to unauthenticated RCE; patches released and CISA added both to KEV.

SonicWall disclosed and patched two zero-days in SMA 1000 appliances: CVE-2026-83548, a maximum-severity pre-authentication SSRF, and CVE-2026-83549, a high-severity OS command injection. Rapid7 said chaining the flaws yields unauthenticated remote code execution, and CISA added both to its KEV catalog Wednesday. The vendor provided no IOCs or victim counts, urging customers to hunt for compromise, reimage or redeploy appliances, and reset all passwords and tokens. The product has faced repeated exploitation, including ransomware-linked flaws used by INC and Akira.

Attackers Exploit Critical Langflow and Rails Flaws in Credential

VulnCheck reports active exploitation of critical Langflow CVE-2026-0768 and Rails CVE-2026-66066 for credential harvesting, with detections rising to 360.

VulnCheck observed active exploitation of CVE-2026-0768 (CVSS 9.8) in Langflow and CVE-2026-66066 'KindaRails2Shell' (CVSS 9.5) in Ruby on Rails, with detections rising from 50 on August 30, 2026 to 360 by September 1. The Rails flaw allows unauthenticated arbitrary file reads, leaking secret_key_base, Rails master key, database passwords, cloud credentials and API tokens, ultimately enabling RCE; the patch still leaves the variation-key Marshal deserialization RCE gadget functional. Observed chains include a Python credential harvester with SimpleHelp remote access via CVE-2026-5027, and weaponization of CVE-2025-3248 to enlist hosts into an XMR mining botnet after disabling auditd. More than 7,100 exposed vulnerable Ruby on Rails instances and over 15,000 successful exploitation attempts across three Langflow flaws were recorded.
