AI-suggested
Upgrade PraisonAIAgents to version 1.5.128 or later, where this vulnerability is fixed. Since no official vendor advisory or patch link is provided, verify the update directly from the vendor or trusted sources. Until patched, restrict access to the affected versions and monitor for suspicious activity related to file access by agents.
Description
PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, read_skill_file() in skill_tools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skill_path parameter. Unlike file_tools.read_file which enforces workspace boundary confinement, and unlike run_skill_script which requires critical-level approval, read_skill_file has neither protection. An agent influenced by prompt injection can exfiltrate sensitive files without triggering any approval prompt. This vulnerability is fixed in 1.5.128.
