✅ Remediation

Red Hat Trusted Artifact Signer simplifies cryptographic signing and verifying of software artifacts such as container images, binaries and source code changes. It is a self-managed on-premise deployment of the Sigstore project available at https://sigstore.dev Platform Engineers, Software Developers and Security Professionals may use RHTAS to ensure the integrity, transparency and assurance of their organization's software supply chain. For details on using the operator, refer to the product documentation at https://access.redhat.com/documentation/en-us/red_hat_trusted_artifact_signer/1.2 You can find the release notes for this version of Red Hat Trusted Artifact Signer at https://access.redhat.com/documentation/en-us/red_hat_trusted_artifact_signer/1.2/html-single/release_notes/index Workaround: To mitigate this issue, implement strict input validation before passing any property paths to the _.unset and _.omit functions to block attempts to access the prototype chain. Ensure that strings like __proto__, constructor and prototype are blocked, for example. Workaround: To mitigate this issue, avoid using the `glob` command-line interface with the `-c` or `--cmd` option when processing filenames from untrusted sources. If programmatic use of `glob` is necessary, ensure that filenames are thoroughly sanitized before being passed to commands executed with shell interpretation enabled. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
