Summary Open WebUI lets a user who can create, update, or import workspace models store arbitrary meta.knowledge entries on their model without checking whether they own or can read the referenced files. Open WebUI then treats meta.knowledge entries of type file as an authorization source in two...

CVE-2026-62186: Missing Authorization

OpenClaw versions before 2026.6.8 contain an authorization bypass vulnerability in OpenAI-compatible HTTP model overrides that allows lower-trust callers to perform actions requiring stronger authorization checks. Attackers can exploit misconfigured input paths to bypass admin authorization...

Summary The /responses endpoint in the OpenAI router accepts any authenticated user and forwards requests directly to upstream LLM providers without enforcing per-model access control. While the primary chat completion endpoint generate chat completion checks model ownership, group membership, an...

PraisonAI’s MCP Model Context Protocol integration allows spawning background servers via stdio using user-supplied command strings e.g., MCP"npx -y @smithery/cli ...". These commands are executed through Python’s subprocess module. By default, the implementation forwards the entire parent proces...

OpenMed before 1.5.2 contains a remote code execution vulnerability in the PII privacy-filter model loading path. The privacy-filter dispatcher used broad substring matching on the user-supplied model name parameter, allowing a value such as attacker/foo-privacy-filter-bar to route through a path...

Summary Several direct, index-addressed Ollama proxy routes accept a caller-supplied url idx path parameter and use it as a raw index into the admin-configured OLLAMA BASE URLS list. Access control on these routes validates only whether the user may use the requested model, never which backend th...
