Capgo before 12.128.2 allows upload-scoped API keys to modify the mutable appversions.r2path field through PostgREST, enabling retargeting to arbitrary R2 bundle objects. Attackers can patch r2path to point to victim objects, soft-delete the attacker-controlled version, and trigger the onversion_update cleanup function to delete the victim R2 object, causing denial of service and bundle availability disruption.
