- Mitigation guidance
- Ensure the s3_acl configuration option is set to false (the default) in the [filter:s3api] section of proxy-server.conf. This completely mitigates the vulnerability because Swift's native authorization (Keystone/tempauth) will properly deny cross-tenant access attempts. If s3_acl=true is required and cannot be changed, restrict S3 API access to trusted networks or remove the s3api filter from the proxy-server pipeline until the patch is applied.
