CVE-2026-34939 PraisonAI: ReDoS via Unvalidated User-Controlled Regex in MCPToolIndex.search_tools()

PraisonAI is a multi-agent teams system. Prior to version 4.5.90, MCPToolIndex.searchtools 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...
