PYSEC-2026-3886 PraisonAI has a Browser Server WebSocket origin validation bypass via unanchored regex (patch bypass of CVE-2026-40289 / GHSA-8x8f-54wf-vv92)
Summary praisonai/browser/server.py validates incoming WebSocket connections using a Chrome extension Origin check. The regex chrome-extension://a-z0-932 is applied with re.match, which only anchors at the start of the string, not the end. Any Origin header with more than 32 alphanumeric characte...
PraisonAI: Origin-validation bypass (startswith prefix match) enables unauthenticated cross-site request forgery against the PraisonAI MCP HTTP server
SummaryThe PraisonAI MCP server exposes an HTTP-stream transport praisonai mcp serve --transport http-stream that binds to localhost and, by default, has no API key. Its only access control for browser-originated requests is an Origin allowlist, which the code implements as required by the MCP...

PYSEC-2026-3889 PraisonAI: Authentication fail-open in Recipe server allows unauthenticated access when API key or JWT auth is configured without a secret
Summary The PraisonAI Recipe HTTP server silently allows unauthenticated requests when auth is configured as api-key or jwt but the corresponding secret is missing. This creates an authentication fail-open condition. An operator can start the Recipe server with authentication enabled, including o...
PYSEC-2026-3885 PraisonAI: [Auth Bypass] PraisonAI async Jobs API (`/api/v1/runs`) has no authentication — unauthenticated job execution, result theft, cancel and delete
Summary PraisonAI's async Jobs API the FastAPI service in praisonai/jobs/ installs its router with no authentication middleware, no router-level dependency, and no per-route auth check. Any caller who can reach the jobs server can submit agent jobs executed against the operator's configured LLM...
