PraisonAIAgents — Prompt Injection (CVE-2026-40117)
Date: 2026-04
Affected: praison/praisonaiagents
Attack vector: prompt-injection
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2026-40117
CWE: CWE-862
CVSS: 6.2 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

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.
