CVE-2026-44017: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in docling-project docling
Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. Prior to 2.91.0, the EasyOCR model download functionality extracted ZIP archives without validating member paths, enabling Zip Slip attacks. If an attacker could compromise the model download source (via supply chain attack, DNS spoofing, or MITM), they could write arbitrary files to any location writable by the process, potentially achieving remote code execution by overwriting Python files or system binaries, persistent backdoors by modifying startup scripts or SSH keys, and data corruption or system compromise. This vulnerability is fixed in 2.91.0.
AI Analysis
Technical Summary
CVE-2026-44017 is a path traversal vulnerability in the docling project affecting versions before 2.91.0. The EasyOCR model download feature extracts ZIP archives without proper validation of file paths inside the archive. This allows an attacker who can intercept or compromise the model download source (e.g., via supply chain attack, DNS spoofing, or man-in-the-middle) to perform Zip Slip attacks. Such attacks enable arbitrary file writes to any location writable by the running process, which can lead to remote code execution by overwriting Python files or system binaries, persistent backdoors by modifying startup scripts or SSH keys, and general system compromise. The vulnerability is addressed in docling version 2.91.0.
Potential Impact
If exploited, this vulnerability allows an attacker to write arbitrary files to the filesystem with the privileges of the docling process. This can result in remote code execution, persistent backdoors, data corruption, and full system compromise. The attack requires the ability to compromise the model download source or intercept the download process.
Mitigation Recommendations
This vulnerability is fixed in docling version 2.91.0. Users should upgrade to version 2.91.0 or later to remediate this issue. There is no official patch or temporary fix other than upgrading. Until upgraded, users should ensure the integrity and authenticity of the model download source to prevent supply chain or man-in-the-middle attacks.
