Detailsinfo

A vulnerability classified as problematic has been found in MervinPraison PraisonAIAgents up to 1.5.127. This affects the function read_skill_file of the file skill_tools.py. The manipulation of the argument skill_path with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on confidentiality. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-40117 since 04/09/2026. The exploitability is told to be easy. An attack has to be approached locally. Technical details are known, but no exploit is available.

Upgrading to version 1.5.128 eliminates this vulnerability.
