What is CVE-2026-54520?

CVE-2026-54520 is a high-severity path traversal vulnerability in vmDeshpande ai-agent-automation, published on 17 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

AI Agent Automation is a modular AI agent workflow automation platform with schedulers, tools, and observability. Prior to 0.9.1, the executeStep file-step implementation in backend/src/agents/executor.js passes the user-controlled step.path value through path.resolve with process.cwd() and then uses the resulting path for read or write operations without checking that it remains in an approved workflow directory. An authenticated user who can create or modify workflow file steps can supply traversal segments to escape the intended workspace and read sensitive files or write and overwrite files accessible to the backend process, including application-adjacent files when process permissions allow. This issue is fixed in version 0.9.1.
