Title

SABnzbd: Orphan-job path traversal permits arbitrary file deletion

Summary

SABnzbd is an open source automated Usenet download tool. Prior to 5.1.0Beta3, orphan-job management in `sabnzbd/api.py` accepts the user-controlled `value` parameter without path confinement before `os.path.join()` with `download_dir`. An absolute path discards that base directory. An attacker with a valid API key can invoke `mode=status` with `name=delete_orphan` to reach `_api_delete_orphan` and `remove_all()` in `sabnzbd/filesystem.py`, which uses `shutil.rmtree()` for recursive deletion. The advisory also identifies `_api_add_orphan` and `_api_delete_all_orphan` as affected by the path-validation issue, while its concrete arbitrary-deletion trace is through `_api_delete_orphan`. The API key is stored in plaintext in `sabnzbd.ini`. The attacker can delete files or directories writable by the SABnzbd process, including configuration, queue data, and downloads, but system files outside the regular user's ownership are not affected. This issue is fixed in version 5.1.0Beta3.

UBUNTU-CVE-2026-62965 (CVE-2026-62965)

Vulnerability from osv_ubuntu – Published: 2026-11-03 00:00 – Updated: 2026-11-03 00:00 – Source website

Details

SABnzbd is an open source automated Usenet download tool. Prior to 5.1.0Beta3, orphan-job management in sabnzbd/api.py accepts the user-controlled value parameter without path confinement before os.path.join() with download_dir. An absolute path discards that base directory. An attacker with a valid API key can invoke mode=status with name=delete_orphan to reach _api_delete_orphan and remove_all() in sabnzbd/filesystem.py, which uses shutil.rmtree() for recursive deletion. The advisory also identifies _api_add_orphan and _api_delete_all_orphan as affected by the path-validation issue, while its concrete arbitrary-deletion trace is through _api_delete_orphan. The API key is stored in plaintext in sabnzbd.ini. The attacker can delete files or directories writable by the SABnzbd process, including configuration, queue data, and downloads, but system files outside the regular user's ownership are not affected. This issue is fixed in version 5.1.0Beta3.

  "details": "SABnzbd is an open source automated Usenet download tool. Prior to 5.1.0Beta3, orphan-job management in `sabnzbd/api.py` accepts the user-controlled `value` parameter without path confinement before `os.path.join()` with `download_dir`. An absolute path discards that base directory. An attacker with a valid API key can invoke `mode=status` with `name=delete_orphan` to reach `_api_delete_orphan` and `remove_all()` in `sabnzbd/filesystem.py`, which uses `shutil.rmtree()` for recursive deletion. The advisory also identifies `_api_add_orphan` and `_api_delete_all_orphan` as affected by the path-validation issue, while its concrete arbitrary-deletion trace is through `_api_delete_orphan`. The API key is stored in plaintext in `sabnzbd.ini`. The attacker can delete files or directories writable by the SABnzbd process, including configuration, queue data, and downloads, but system files outside the regular user\u0027s ownership are not affected. This issue is fixed in version 5.1.0Beta3.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
