How to Fix CVE-2026-55474

To remediate this vulnerability, upgrade all affected Snipe/snipe it dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

snipe/snipe-it fixed: 8.5.0
Upgrade snipe/snipe-it to 8.5.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for snipe/snipe-it

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-55474, inspect your project dependencies for Snipe/snipe it:

inspect dependencies for snipe/snipe-it

Analyze the terminal output to locate any version of Snipe/snipe it in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.5.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-23: Relative Path Traversal, where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. In Snipe/snipe it, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The `displaySig` action in `ActionlogController` serves signature image files from a private upload directory. The filename parameter from the HTTP route is concatenated directly into a filesystem path with no sanitization, allowing an authenticated attacker to traverse outside the intended directory and read arbitrary files accessible to the web server process.
