high Tenable Cloud Security Plugin ID 439626

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PraisonAI is a multi-agent teams system. Prior to version 4.5.90, MCPToolIndex.search_tools() compiles a
 caller-supplied string directly as a Python regular expression with no validation, sanitization, or
 timeout. A crafted regex causes catastrophic backtracking in the re engine, blocking the Python thread for
 hundreds of seconds and causing a complete service outage. This issue has been patched in version 4.5.90.
 (CVE-2026-34939)

Solution

Update the praisonai library and its related packages to version 4.5.90 or later.
