DescriptionCVE.org

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.

AnalysisAI

Cross-tenant bundle deletion in Capgo (Capacitor live/OTA update platform) before 12.128.2 lets holders of an upload-scoped API key rewrite the mutable app_versions.r2_path column through the PostgREST data API, retargeting it at another tenant's Cloudflare R2 objects. By pointing a soft-deleted attacker version at a victim bundle and firing the on_version_update cleanup trigger, an attacker deletes the victim's R2 object, breaking that app's over-the-air update delivery. …
