Detailsinfo

A vulnerability was found in OpenSift up to 1.6.2. It has been classified as critical. This affects an unknown code block. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

OpenSift is an AI study tool that sifts through large datasets using semantic search and generative AI. Prior to version 1.6.3-alpha, multiple storage helpers used path construction patterns that did not uniformly enforce base-directory containment. This created path-injection risk in file read/write/delete flows if malicious path-like values were introduced. This issue has been patched in version 1.6.3-alpha.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-28676 since 03/02/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

Upgrading to version 1.6.3-alpha eliminates this vulnerability. The upgrade is hosted for download at github.com. Applying the patch 1126e0a503876056a68a434e19f64158a5a4840b is able to eliminate this problem. The bugfix is ready for download at github.com.
