Summary
A vulnerability in Docling before version 2.91.0 allows Zip Slip attacks during EasyOCR model downloads. An attacker can overwrite arbitrary files, leading to remote code execution, persistent backdoors, or data corruption.
Risk Assessment
The risk includes server compromise via remote code execution, persistent backdoors, and data corruption, potentially leading to full security breach of the organization.
Recommendation
Immediately upgrade Docling to version 2.91.0 or later. Additionally, secure model download sources against supply chain attacks, DNS spoofing, and MITM attacks.
Original NVD description (English source)
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.
