AI-suggested
A fix is available that resolves extraction destination paths before writing and rejects any extraction attempts that resolve outside the designated extraction directory. Users should upgrade to a version later than 1.12.7 where this validation is implemented.
Description
Pandora-analysis pandora versions up to 1.12.7 contain a critical path traversal vulnerability in the archive extraction worker. This flaw allows an attacker submitting a malicious archive or disk image to cause files to be extracted outside the intended directory, potentially overwriting system or application files. Exploitation could lead to unauthorized file modification, denial of service, or further system compromise depending on the Pandora process permissions. The vulnerability is addressed by validating resolved extraction paths to ensure they remain within the designated directory and rejecting attempts that traverse outside.
Impact
Successful exploitation allows an unauthenticated attacker who can submit files for analysis to write files outside the intended extraction directory. This can lead to unauthorized modification of application or system files, denial of service, and potentially further compromise depending on the permissions of the Pandora worker process and the files it can overwrite. The CVSS 4.0 score of 9.3 reflects a critical severity with network attack vector, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Summary
CVE-2026-88069 is a path traversal vulnerability (CWE-22) in the pandora-analysis pandora product affecting versions up to 1.12.7. The issue arises because the archive extraction worker does not properly restrict file extraction paths, allowing attacker-controlled paths in specially crafted archives or disk images to escape the intended extraction directory. This can result in overwriting files accessible to the Pandora process. The fix involves resolving each extraction path before writing and verifying it remains within the extraction directory, rejecting any paths that resolve outside.

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
