How to Fix CVE-2025-56760

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

github.com/usememos/memos fixed: Latest secure release 
Upgrade github.com/usememos/memos to Latest secure release
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 github.com/usememos/memos

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-56760, inspect your project dependencies for Github.com/usememos/memos:

inspect dependencies for github.com/usememos/memos

Analyze the terminal output to locate any version of Github.com/usememos/memos in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-24: Path Traversal: '../filedir', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "../" sequences that can resolve to a location that is outside of that directory. In Github.com/usememos/memos, 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

When Memos 0.22 is configured to store objects locally, an attacker can create a file via the CreateResource endpoint containing a path traversal sequence in the name, allowing arbitrary file write on the server.
