## What is CVE-2026-56836?

CVE-2026-56836 is a high-severity vulnerability in MervinPraison PraisonAI, published on 23 Oct 2026. 

### Official description

PraisonAI is a multi-agent teams system. From version 4.5.112 to before version 4.6.59, PraisonAI's installed console entrypoint is Typer-first. In current releases, the recipe command is registered in the Typer app and praisonai recipe serve dispatches to the deprecated Typer command in src/praisonai/praisonai/cli/commands/recipe.py. That Typer command can start the Recipe HTTP server on a non-localhost interface with no authentication. It prints a deprecation warning, and then launches the server. Because config.auth is absent, create_app() does not attach the API-key or JWT middleware. Unauthenticated requests can then reach the recipe API and, when enabled, /admin/reload. This issue has been patched in version 4.6.59.

Weakness: CWE-862 (Missing Authorization), CWE-306 (Missing Authentication for Critical Functionality), CWE-287 (Improper Authentication)
