CVE-2026-34953: CWE-863: Incorrect Authorization in MervinPraison PraisonAI
PraisonAI is a multi-agent teams system. Prior to version 4.5.97, OAuthManager.validate_token() returns True for any token not found in its internal store, which is empty by default. Any HTTP request to the MCP server with an arbitrary Bearer token is treated as authenticated, granting full access to all registered tools and agent capabilities. This issue has been patched in version 4.5.97.

Exploitation of this vulnerability allows an unauthenticated attacker to gain full access to all registered tools and agent capabilities within the PraisonAI system. This could lead to unauthorized actions and compromise of the system's integrity and confidentiality. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade PraisonAI to version 4.5.97 or later, where this authorization flaw has been patched. Since this is a product-level vulnerability and not a cloud service, applying the official fix is required to remediate the issue. Patch status is confirmed by the vendor's versioning information.
