CVE-2026-12701

Descripción

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.
