CVE-2026-12701
CriticalCVSS 9.0Exploitation Probability (EPSS)
Elevated risk51th percentile - higher than 51% of all known CVEs
Summary
A path traversal vulnerability was found in pulpcore. The relative_path_validator function only checks that paths do not begin with "/" but fails to block sequences like "../". An authenticated administrator can craft a relative_path containing traversal sequences, allowing arbitrary file write to any location writable by the Pulp service user.
Risk Assessment
An attacker can overwrite critical system files, potentially leading to compromise of the Pulp service and further system exploitation.
Recommendation
Apply patches for pulpcore that fix path validation. Restrict administrator privileges and monitor export operations.
Original NVD description (English source)
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.
