Windows Remote Desktop Client Vulnerability Allows Attackers to Execute Remote Code
Microsoft patched CVE-2026-69485, an 8.8 CVSS RCE flaw in the Windows Remote Desktop Client affecting Windows 10/11 and Server 2016-2025.
Microsoft's September 2026 updates fix CVE-2026-69485, an Important-rated remote code execution vulnerability (CVSS 3.1: 8.8, temporal 7.7) in the Windows Remote Desktop Client caused by use of an uninitialized resource. An authenticated attacker with low privileges could send a specially crafted network request to execute code on an affected server, with no user interaction required. Microsoft says the flaw was not publicly disclosed before patching and rates exploitation as 'Less Likely' with no evidence of active exploitation. Affected products span Windows Server 2016, 2019, 2022 and 2025 and Windows 10 (1607-22H2) and Windows 11 (23H2-26H1), with fixes delivered via KBs including KB5123099, KB5122876 and KB5122882.

GitLab Patches Critical Flaws Enabling Arbitrary File Read, Credential Theft and Remote Code Execution
GitLab patched a CVSS 10.0 path traversal (CVE-2026-85706) plus deserialization and buffer-overflow flaws, urging self-managed users to update immediately.
GitLab released versions 19.3.2, 19.2.6, and 19.1.8 on September 10, 2026, fixing CVE-2026-85706 (CVSS 10.0), an unauthenticated path traversal in the repository commits API enabling arbitrary file reads on both Community and Enterprise Editions. CVE-2026-87719 (CVSS 9.9) is insecure deserialization in the EE GraphQL subscription serializer that can expose Advanced Search configurations and credentials, while CVE-2026-88765 (CVSS 8.5) allows authenticated RCE via crafted project exports. The update includes database migrations, so single-node deployments will experience downtime; GitLab.com is already patched.

Critical ArangoDB Flaws Allow Authentication Bypass and Remote Code Execution as Root
Two critical ArangoDB flaws (CVSS 9.8 and 9.9) enable unauthenticated API access and root code execution; fixes shipped in version 3.12.11
Remedio researchers found two ArangoDB flaws: GHSA-rrgq-978q-36mq (CVSS 9.8), an authentication bypass caused by the server inconsistently interpreting URL-encoded '/_api' paths, and GHSA-rvhw-4hpw-9vrx (CVSS 9.9), which lets users with database write access run JavaScript tasks with root privileges via the isSystem flag. Chained, they allow administrative database access without credentials, theft of the root password hash, and root code execution, exposing files such as /etc/shadow, TLS keys and cluster signing material on the official container image. ArangoDB shipped fixes in version 3.12.11 on August 31, 2026, with advisories published September 6; CVE identifiers were still pending. Users on 3.12.10.1 or earlier should upgrade, restrict exposure and rotate potentially exposed credentials.

[remote] PraisonAI praisonaiagents 1.6.77 - Remote Code Execution
Public RCE exploit targets PraisonAI praisonaiagents 1.6.77, an open-source multi-agent AI framework.
Exploit-DB entry 52639 publishes a remote code execution exploit against praisonaiagents 1.6.77, the agent library from PraisonAI used for building LLM-powered multi-agent applications. The PoC demonstrates how attackers could achieve arbitrary code execution on deployments running the vulnerable version. This continues a pattern of serious flaws surfacing in rapidly developed AI agent frameworks.
