CVE-2026-58658 HIGH POC PATCH This Week

Unauthenticated information disclosure in GPUStack through version 2.2.1 lets remote attackers reach the worker port's unprotected /serveLogs and /debug endpoints to stream live inference logs - including user prompts and model completions - and to alter worker runtime configuration such as log levels and memory profiling output. Because the flaw is missing authentication (CWE-306) on network-exposed endpoints, exploitation requires no credentials and no user interaction; publicly available exploit code exists, though the issue is not listed in CISA KEV. VulnCheck reported it and the vendor fixed it in commit 4e20551.

CVE-2026-61613 HIGH PATCH This Week

Server-side request forgery leading to code execution in Cursor's browser-enabled Cloud Agent lets attacker-controlled web content reach an unauthenticated local agent endpoint from inside the sandbox, compromising the session. Affecting Cursor Cloud Agent sessions prior to the 03/31/2026 fix, an attacker who gets a browsing agent to load malicious content can run code in the sandbox and read repository contents, environment variables, credentials, and GitHub App access tokens scoped to that session. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the flaw is a missing-authentication (CWE-306) authentication-bypass class issue with high confidentiality, integrity, and availability impact to the affected session.

CVE-2026-48325 CRITICAL Act Now

Missing authentication in Adobe ColdFusion allows an unauthenticated attacker on an adjacent network to trigger arbitrary code execution in the context of the current user, without any user interaction. The flaw (CWE-306) bypasses authentication on a critical function and carries a scope change, meaning the impact reaches beyond the vulnerable component. There is no public exploit identified at time of analysis, but the issue was reported by Adobe PSIRT and addressed in advisory APSB26-82.

CVE-2026-54446 PyPI HIGH POC PATCH GHSA This Week

Unauthenticated abuse of the operator's NetLicensing credential affects Labs64 netlicensing-mcp (FastMCP server) versions <= 0.1.5 when run in HTTP transport mode. The ApiKeyMiddleware forwards requests that carry no client API key straight to the tool handlers, and the downstream client falls back to the server-side NETLICENSING_API_KEY environment variable, so any network-reachable attacker can invoke every MCP tool (list/create/update/delete of products, licenses, licensees, tokens) under the operator's identity and account quota. Publicly available exploit code exists (a self-contained Docker/Python PoC in the advisory), no public active exploitation is confirmed, and the issue is fixed in 0.1.6.

Missing authentication in NVIDIA TensorRT-LLM for Linux lets an attacker reach the disaggregated orchestrator's FastAPI server directly and read, write, or delete internal cluster state, resulting in information disclosure, data tampering, and denial of service. The flaw (CWE-306) affects the orchestration layer that coordinates disaggregated prefill/decode inference workers. No public exploit identified at time of analysis, and the CVSS 3.1 base score is 7.3 with a local attack vector despite the request-based nature of the issue.

Missing authentication in Adobe Experience Manager (AEM as a Cloud Service, 6.5, and 6.5 LTS) lets a remote unauthenticated attacker reach a critical function directly, bypassing a security control to gain unauthorized write access. The CVSS 8.6 rating and scope-change flag indicate impact can extend beyond the initially vulnerable component, though only integrity is affected (no confidentiality or availability loss). No public exploit identified at time of analysis, and it is not listed in CISA KEV.

Privilege elevation in Microsoft's Windows Server Update Services (WSUS) role allows a network-based, low-privileged attacker to gain higher privileges due to a missing authentication check on a critical function (CWE-306). The flaw affects WSUS as shipped on Windows Server 2012 through 2025 (and client builds Windows 10 1607/1809), with a CVSS 3.1 base score of 8.8; Microsoft has released a patch. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the network-reachable, low-complexity nature makes this a high-priority patch for update-management infrastructure.

Local privilege escalation in Windows Routing and Remote Access Service (RRAS) allows a low-privileged authenticated user to elevate to higher privileges on affected Windows 10, Windows 11, and Windows Server 2012 through 2025 systems. The flaw stems from a missing authentication check on a critical RRAS function (CWE-306), letting an already-authorized local attacker invoke privileged functionality without proper authorization. Microsoft has released a patch; there is no public exploit identified at time of analysis.

Local privilege escalation in the Windows Spaceport.sys Storage Spaces driver lets an already-authenticated low-privileged user gain SYSTEM-level control across Windows 10, Windows 11, and Windows Server 2016 through 2025. The flaw stems from a missing authentication check on a critical driver function (CWE-306), and Microsoft has released a patch; no public exploit has been identified at time of analysis. With CVSS 7.8 (local, low-privilege) and full confidentiality, integrity, and availability impact, it is a strong candidate for chaining after an initial foothold.
