gogs.io/gogs fixed: 0.12.9

Upgrade gogs.io/gogs to 0.12.9

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 gogs.io/gogs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-1992, inspect your project dependencies for Gogs.io/gogs:

inspect dependencies for gogs.io/gogs

Analyze the terminal output to locate any version of Gogs.io/gogs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.9), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where 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. In Gogs.io/gogs, software state validation or input boundaries are circumvented during processing.
