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...

PYSEC-2026-3915 qwed-mcp has Unsafe SymPy `parse_expr()` Remote Code Execution via Unsanitized Math Expression Input

Summary verifymathexpression in qwed-mcp v0.2.0 passes attacker-controlled strings directly to SymPy's parseexpr without restricting globaldict or validating the expression's AST. Because parseexpr internally calls eval and Python automatically injects the current module's builtins when no explic...

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...

PraisonAI serve agents --api-key is ignored, allowing unauthenticated remote agent execution

Summary PraisonAI's praisonai serve agents command exposes --api-key as the documented authentication control for production/external deployments, but the configured key is not enforced on the public agent invocation compatibility endpoints. An operator can start the server with --api-key and bin...

PYSEC-2026-3888 PraisonAI: [Path Traversal] agent tools escape the configured workspace via symlinks

Summary PraisonAI's praisonai.code tool wrappers exported as CODETOOLS for agents expose a workspace setting that the module itself treats as a path-traversal security boundary — readfile, writefile, applydiff, and searchreplace explicitly call ispathwithindirectory and return "… is outside the...
