CVE-2026-40117: Praison Praisonaiagents

High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Praison Praisonaiagents: before 1.5.128 (fixed in 1.5.128)
