CVE-2026-28676: OpenSift: Insufficient path containment checks in storage helpers could allow path traversal-style file operations

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-22

Description

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.

Affected products

• OpenSift: before 1.6.3 — fixed in 1.6.3

How to fix

Upgrade to a fixed version: OpenSift 1.6.3. Check the vendor advisory for mitigations.
