What is CVE-2026-12701?
CVE-2026-12701 is a critical path traversal vulnerability in Red Hat Ansible Automation Platform 2, published on 20 Jul 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
A path traversal vulnerability was found in pulpcore. The relative_path_validator function only verifies that content paths do not begin with "/" but fails to block directory traversal sequences such as "../" anywhere in the path. An authenticated administrator can craft a relative_path containing embedded traversal sequences (e.g., "looking/normal/../../../../etc/shadow") that escapes the intended export directory during FilesystemExport operations. Because the file content is also user-controlled (uploaded artifact), this allows arbitrary file write to any location writable by the Pulp service user, potentially leading to service compromise or further system exploitation.
Weakness: CWE-22
