Remediation status
The records we use list no fixed version for CVE-2020-36467 (versions up to 2020-12-10 are affected). Check the cgc_project cgc advisory for a patched release, and apply the workarounds below until you can upgrade.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
