CyberRota Analysis
AI-GeneratedBabelDOC versions prior to 0.6.3 are vulnerable due to improper handling of untrusted pickle data in their PDF parser, allowing an attacker to exploit path traversal vulnerabilities and execute arbitrary Python code with the application's privileges. This poses a significant risk, as it could lead to unauthorized access or manipulation of sensitive data. Organizations using BabelDOC should prioritize upgrading to version 0.6.3 to mitigate this high-severity vulnerability.

Original NVD Description
BabelDOC is a document translation tool. Prior to 0.6.3, BabelDOC's vendored PDF parser in babeldoc/pdfminer/cmapdb.py deserializes untrusted pickle data when CMapDB._load_data() loads CMap files. PDF-controlled Encoding or CMapName values and embedded PostScript usecmap operators can reach this sink after path separators are decoded, while _normalize_cmap_name() removes only a leading slash. Absolute paths or traversal sequences can escape the trusted CMap directories through os.path.join(), select an attacker-writable .pickle.gz file, and cause pickle.loads() to execute arbitrary Python code with the privileges of the BabelDOC process. This issue is fixed in version 0.6.3.
