CVE-2026-56836 is an authentication bypass in PraisonAI affecting the deprecated recipe serve Typer command. The vulnerable command path can bind the Recipe HTTP server to a non-localhost interface without enabling authentication, bypassing the intended safeguard that should prevent unauthenticated exposure when listening on non-local interfaces. As a result, deployments started through this deprecated handler may expose recipe API functionality remotely without access controls that operators would reasonably expect to be enforced.

If you can’t patch tonight, do this now.
praisonai recipe serve Typer path for remote binding until patched. Restrict the Recipe HTTP server to localhost only and avoid exposing it on non-localhost interfaces such as 0.0.0.0 unless authentication is explicitly configured and verified. Disable administrative endpoints where possible, and reduce reachability through firewall rules, segmentation, or other network access controls. If remote access is operationally necessary, require and validate authentication before exposure.Patch, then assume compromise.
praisonai recipe serve Typer command, or ensure it delegates to the hardened handler. Apply the same non-localhost-without-authentication guard to cli/commands/recipe.py, correct command help and examples so remote binding always requires authentication, and add regression tests covering the installed entrypoint behavior to prevent reintroduction of the flaw.No public exploits tracked yet.
