How to Fix CVE-2022-42968

To remediate this vulnerability, upgrade all affected Github.com/go gitea/gitea 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/go-gitea/gitea fixed: 1.17.3 
Upgrade github.com/go-gitea/gitea to 1.17.3
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/go-gitea/gitea

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-42968, inspect your project dependencies for Github.com/go gitea/gitea:

inspect dependencies for github.com/go-gitea/gitea

Analyze the terminal output to locate any version of Github.com/go gitea/gitea in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.17.3), 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-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. In Github.com/go gitea/gitea, 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

Gitea before 1.17.3 does not sanitize and escape refs in the git backend. Arguments to git commands are mishandled.
