Name of the Vulnerable Software and Affected Versions Gitleaks versions prior to 8.30.1

Description A template injection issue exists where attackers who can supply or influence report templates can read arbitrary environment variables and exfiltrate sensitive data. This is achieved by leveraging non-hermetic Sprig template functions, which are functions that can access or modify the external environment. Specifically, attackers can use the env, expandenv, and getHostByName functions to extract credentials, tokens, and API keys from the host process and exfiltrate them via DNS queries, including secrets identified during the scan.

Recommendations Update Gitleaks to version 8.30.1 or later.
