AI-suggested
Red Hat states that existing mitigation options do not meet their criteria for ease of use, applicability, or stability. The GODEBUG environment variable htmlmetacontenturlescape can be set to 0 to disable URL escaping in meta content attributes, but this is not recommended as a reliable mitigation. No additional vendor-recommended mitigations are provided at this time.
