CVE-2026-56250
HighCVSS 7.5Summary
A vulnerability in Capgo before version 12.128.2 allows upload-scoped API keys to modify the app_versions.r2_path field via 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.
Risk Assessment
The organization risks losing availability of critical R2-stored resources, potentially disrupting application functionality and dependent services.
Recommendation
Immediately upgrade Capgo to version 12.128.2 or later. Restrict API key permissions to the minimum necessary and monitor logs for unauthorized r2_path modifications.
Original NVD description (English source)
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.
