CERN will move its 2,200-machine accelerator-control fleet from Red Hat-derived distributions to Debian 13, completing the transition by Q4 2026.
CERN engineers announced at MiniDebConf Winterthur that accelerator-control systems, spanning more than 2,200 front-end computers and 17,000 embedded devices, will migrate from Red Hat-derived distributions to Debian 13 ('Trixie'). The trigger was RHEL 9's x86-64-v2 and RHEL 10's x86-64-v3 compiler baselines, which would obsolete legacy Core 2-era and custom industrial boards built for 10-15 year lifecycles. Debian was chosen for retaining x86-64-v1 baseline support, a large package repository, and PREEMPT_RT real-time patch integration in mainline kernels. CERN's compute farms and Tier-0 grid infrastructure will remain on AlmaLinux and RHEL.
Wiz found multiple LiteLLM AI gateway flaws, including a CVE-2026-59822 MCP auth bypass added to CISA KEV, enabling root code execution and cloud credential theft.
An internet scan of 3,074 exposed LiteLLM instances found 294 (9.6%) accepting the default sk-1234 master key and 191 (6.2%) requiring no authentication. CVE-2026-59822 lets a single-character Bearer token establish a valid MCP session via an OAuth2 fallback in versions before 1.84.0; the flaw is in CISA's Known Exploited Vulnerabilities catalog. CVE-2026-59821 allows Python code execution as root in the gateway container via unsanitized Custom Code Guardrails registration before 1.82.0-stable, and CVE-2026-35029 permits config changes leading to RCE and admin takeover. Admin access plus pass-through endpoints can reach cloud metadata services to steal IAM credentials.

AFP and FBI arrested two alleged TeamPCP hackers behind open-source supply chain attacks that stole 500,000+ credentials from 1,000+ organizations.
Australian Federal Police, working with the FBI and Western Australia Police, arrested a 21-year-old from Cottesloe and a 23-year-old from Mandurah on August 26, 2026, over alleged membership in the TeamPCP cybercrime group. The group allegedly planted malicious code in open-source packages, harvesting credentials, authentication tokens and at least 300 GB of data from over 1,000 organizations, with remediation costs estimated in the hundreds of millions of dollars. TeamPCP has been linked to supply chain attacks on GitHub, Telnyx, LiteLLM, Aqua Trivy, Checkmarx KICS, TanStack, MistralAI and Red Hat using a cloned self-replicating worm dubbed Shai-Hulud. Researchers note TeamPCP cloned the Shai-Hulud worm but was not behind the original 2025 attacks.
Red Hat patched critical Keycloak flaw CVE-2026-18963 (CVSS 9.1) allowing unauthenticated attackers to take over any account, including administrative ones.
Keycloak and Red Hat patched CVE-2026-18963, a CVSS 9.1 flaw (CWE-640) caused by improper state validation in the reset-credentials flow, letting an unauthenticated remote attacker force a password reset without the emailed action token and achieve full account takeover, including admin accounts. Upstream Keycloak 26.7.2 and Red Hat Build of Keycloak 26.4.15/26.6.6 contain fixes; four RHSA errata were issued August 18, 2026. No evidence of exploitation or public exploits exists as of August 24, 2026; mitigation is disabling the Forgot Password feature in all realms.
Linux kernel flaw CVE-2026-31431 ('Copy Fail', CVSS 7.8) allows unprivileged users to gain root via AF_ALG; a public PoC is out and most distros remain unpatched.
Disclosed on 29 April 2026, CVE-2026-31431 is a local privilege escalation in the Linux kernel's algif_aead module (AF_ALG crypto API), CVSS 7.8, stemming from a 2017 in-place optimisation. By chaining an AF_ALG socket operation with splice(), an unprivileged user can write 4 bytes into an arbitrary page-cache page, e.g. corrupting a setuid binary like /usr/bin/su to obtain a root shell. It affects virtually all kernels built since 2017, including Ubuntu 20.04-24.04, Amazon Linux 2023, RHEL 10.1, and SUSE 16; the mainline fix landed 1 April 2026 but no vendor packages were available as of 30 April. CERT-EU recommends the interim mitigation (disable algif_aead) and blocking AF_ALG via seccomp, prioritising Kubernetes nodes and CI/CD runners.
Unauthenticated .NET Deserialization RCE in Ajax.NET Professional (ajaxpro.2)
Ajax.NET Professional (distributed as the ajaxpro.2 package) is vulnerable to insecure deserialization (CWE-502): it deserializes arbitrary .NET classes supplied by the client without validating which types may be instantiated. Because AjaxPro exposes HTTP endpoints for browser-to-server AJAX calls, a remote, unauthenticated attacker can send a crafted serialized payload to any reachable AjaxPro endpoint and abuse .NET deserialization gadget chains to execute code on the server. Successful exploitation yields full remote code execution with high impact on confidentiality, integrity, and availability (CVSS 3.1 score of 9.8, network vector, no privileges or user interaction required). Any application running any version of ajaxpro.2 / Ajax.NET Professional is affected; the provided data specifies no fixed version, so defenders must rely on vendor guidance for patched releases. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-26, carries an EPSS 30-day exploitation probability of 83.6%, has public PoC code available, and Talos Intelligence reporting links it to the Chinese-speaking threat actor UAT-10147, which deploys the SPECTRE malware with an EDR bypass and a Linux rootkit in post-compromise operations.

Remote Code Execution in Microsoft SQL Server 2016 and 2017
CVE-2019-1068 is a remote code execution vulnerability in Microsoft SQL Server caused by improper handling of the processing of internal functions (CWE-20, improper input validation). An attacker who can reach SQL Server over the network with low-privileged credentials can trigger the flawed code path and execute arbitrary code, gaining high confidentiality, integrity, and availability impact on the database host. Any organization running affected Microsoft SQL Server versions — including SQL Server 2016 and SQL Server 2017 — is affected. The flaw carries a high EPSS score (52.8% probability of exploitation within 30 days, 99th percentile) and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-26, with headlines reporting it being exploited in active attacks. No public proof-of-concept is known, but the in-the-wild exploitation documented by CISA makes patching urgent; the fix shipped in Microsoft's July 2019 Patch Tuesday security updates.

Memory Buffer Overflow in Citrix NetScaler ADC/Gateway Exploited in the Wild
CVE-2026-8452 is a memory buffer overflow (CWE-119) in Citrix NetScaler ADC and NetScaler Gateway that applies when the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, or RDP Proxy) or as an AAA virtual server. The flaw is reachable over the network without authentication (CVSS 4.0: AV:N/PR:N), so an unauthenticated attacker can trigger it remotely. Successful exploitation causes unpredictable or erroneous appliance behavior and denial of service, and the high confidentiality score suggests possible disclosure of memory contents; some reporting suggests pre-authentication remote code execution may be possible, though the vendor description emphasizes DoS. Organizations running affected NetScaler appliances in a Gateway or AAA role — a very common configuration for remote access to Citrix virtual apps and desktops — are potentially exposed. The flaw was added to CISA's KEV catalog on 2026-08-26 and is reported as exploited in the wild, with headlines noting the flaw was already patched before exploitation was confirmed.
Out-of-Bounds Write in Linux Kernel watch_queue Enables Local Privilege Escalation
CVE-2022-0995 is an out-of-bounds (OOB) memory write in the Linux kernel's watch_queue event notification subsystem (CWE-787) that can overwrite parts of kernel state. A local user can trigger it through the watch_queue interface, for example by supplying a crafted event filter definition, causing the kernel to write beyond allocated memory when event notifications are processed. Successful exploitation may allow the local user to gain privileged (kernel/root) access or crash the system, yielding high impact on confidentiality, integrity, and availability (CVSS 3.1: 7.8, local attack vector). Affected systems include mainstream Linux kernels (Fedora is explicitly listed) and NetApp HCI appliance firmware products that ship the affected kernel. The flaw is confirmed exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-26, two public proof-of-concepts are available, and EPSS puts 30-day exploitation probability at 9.5% (95th percentile), though ransomware use is unconfirmed.

Local Privilege Escalation via Symlink Attack in Red Hat ABRT
CVE-2015-5287 is a privilege escalation flaw in Red Hat's Automatic Bug Reporting Tool (ABRT) in which a local user with certain permissions can gain elevated privileges via a symlink attack against a file with a predictable name. Exploitation requires local access to an affected system; an attacker who triggers the flawed file-handling behavior can elevate their privileges on that machine. It affects deployments running ABRT, which ships by default with Red Hat Enterprise Linux and related distributions, including systems that may now be end-of-life or end-of-service. CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-26, indicating exploitation has been observed in the wild, though no public proof-of-concept is known and ransomware use is unknown. EPSS estimates a 5.0% probability of exploitation within 30 days (92nd percentile).

Race Condition in Red Hat libuser Allows Local Privilege Escalation
CVE-2015-3246 is a race condition in Red Hat's libuser, the user-management library used by utilities that modify system accounts, that can cause corruption of the /etc/passwd file during concurrent account updates. An authenticated local user who triggers the race — typically by racing account-modification operations against one another — can desynchronize or corrupt the passwd file. Successful exploitation yields either a denial-of-service condition on the host or, in the privilege-escalation case, elevated (root-level) access by manipulating entries in /etc/passwd. Any Red Hat system shipping the vulnerable libuser library is affected, with risk concentrated on multi-user servers where untrusted local accounts exist. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-26, indicating it is being exploited in the wild, and EPSS assigns it an 8.8% probability of exploitation within 30 days (95th percentile); ransomware use is unknown and no public proof-of-concept is cataloged.

Unauthenticated RCE Chain in IBM Langflow OSS 1.0.0-1.10.0
IBM Langflow OSS 1.0.0 through 1.10.0 contains an unauthenticated code-injection flaw (CWE-94) that can be chained into full remote code execution. An attacker with network access first calls /api/v1/auto_login, which mints a SUPERUSER token to any caller without authentication, then calls /api/v1/validate/code, which executes attacker-supplied code via exec() on the Langflow host. Successful exploitation yields full control of the affected deployment, with high impact on confidentiality, integrity, and availability (CVSS 3.1: 9.8, network-exploitable with no privileges or user interaction required). Anyone running IBM Langflow OSS 1.0.0-1.10.0 is affected, especially default deployments reachable from untrusted networks. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-04, confirming active exploitation; EPSS estimates a 60.6% probability of exploitation within 30 days (99th percentile), and ransomware use is unknown.

Actively Exploited Browser-Based RCE in Ray AI Compute Engine
Ray, the open-source AI compute engine, is vulnerable to a critical remote code execution flaw (CVE-2025-62593, CWE-94/CWE-352) in versions prior to 2.52.0, caused by an insufficient guard against browser-based attacks: the software distinguishes browser traffic only by checking that the User-Agent header starts with 'Mozilla', but the fetch specification allows that header to be modified. An attacker can combine DNS rebinding with a crafted User-Agent so that a developer's Firefox or Safari browser silently sends malicious requests to locally running Ray services after the developer visits an attacker-controlled website or is served a malicious advertisement (malvertising). Successful exploitation yields full remote code execution on the machine running Ray, with high confidentiality, integrity and availability impact reflected in the CVSS 4.0 score of 9.4. Affected users are developers running Ray as a development tool on any version before 2.52.0, which is the fixed release. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-17, a public proof of concept is available in the project's GitHub security advisory (GHSA-q279-jhrf-cc6v), and EPSS estimates a 16.9% probability of exploitation in the next 30 days.

Unauthenticated MCP Endpoint Authentication Bypass in BerriAI LiteLLM
BerriAI LiteLLM, a widely used self-hosted AI gateway and proxy server for calling LLM APIs, fails to properly authenticate requests to its MCP Streamable HTTP endpoint in versions prior to 1.84.0. An unauthenticated attacker can send a fabricated Authorization header that triggers an OAuth2 passthrough fallback, which replaces failed LiteLLM key validation with an empty UserAPIKeyAuth() object and lets the request reach MCP tooling without any valid LiteLLM key. Successful exploitation grants unauthenticated access to the gateway's MCP tooling with high confidentiality impact per the CVSS 4.0 score of 8.8, and public reporting describes attackers chaining LiteLLM weaknesses from authentication bypass to root code execution and cloud credential theft. Any organization running LiteLLM before 1.84.0 is affected, particularly gateways exposed to the internet. The flaw is confirmed exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-09-02, while EPSS currently estimates a 0.9% probability of exploitation in the next 30 days.
