No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Capgo before 12.128.2 allows upload-scoped API keys to modify the mutable app_versions.r2_path field through PostgREST, enabling retargeting to arbitrary R2 bundle objects. Attackers can patch r2_path to point to victim objects, soft-delete the attacker-controlled version, and trigger the on_version_update cleanup function to delete the victim R2 object, causing denial of service and bundle availability disruption.
