PraisonAI - Tool Approval Cache Bypass via Coarse-Grained Caching
Published Jun 18, 2026
6.8
MEDIUMCVSS 4.0
EPSS 0.17%
Description
PraisonAI before 1.5.128 caches tool approval decisions by tool name only, not by invocation arguments, allowing subsequent execute_command calls to bypass approval prompts. Attackers can exploit this by obtaining initial approval for a benign command, then silently exfiltrate API keys and credentials via subsequent shell commands without user consent.
