DescriptionGitHub Advisory

dbt-common is the shared common utilities for dbt-core and adapter implementations use. Prior to versions 1.34.2 and 1.37.3, a path traversal vulnerability exists in dbt-common's safe_extract() function used when extracting tarball archives. The function uses os.path.commonprefix() to validate that extracted files remain within the intended destination directory. However, commonprefix() compares paths character-by-character rather than by path components, allowing a malicious tarball to write files to sibling directories with matching name prefixes. This issue has been patched in versions 1.34.2 and 1.37.3.

AnalysisAI

Path traversal in dbt-common's tarball extraction function allows attackers to write files outside the intended destination directory by exploiting improper path validation in the safe_extract() method. An attacker can craft a malicious tarball to place files in sibling directories, potentially compromising systems using affected versions of dbt-common in dbt-core and adapter implementations. No patch is currently available for this vulnerability.
