AGiXT path traversal in essential_abilities allows arbitrary file access (CVE-2026-39981)
In AGiXT versions prior to 1.9.2, the safe_join() function in the essential_abilities extension did not verify that resolved paths stayed inside the agent workspace, letting an authenticated attacker use directory traversal to read, write or delete arbitrary files on the host. The issue is fixed in release 1.9.2.
