CVE-2026-100622: capgo.app through 12.129.0 Cache Restoration of Deleted Bundles
capgo.app through 12.129.0 fails to verify deletion status when serving cached bundle artifacts from the public file read endpoint. Unauthenticated attackers can download deleted bundles using cached URLs and trigger restoration of deleted objects into R2 storage on cache hits.

Frequently Asked Questions
Who can exploit this issue?
Any unauthenticated remote attacker who has a cached URL for a deleted bundle can exploit the public file read endpoint. No privileges or user interaction are required.
What is exposed if exploitation succeeds?
Deleted bundle artifacts can be downloaded from cache. A cache hit can also restore a deleted object into R2 storage.
Are deployments affected by default?
The affected behavior is in the public file read endpoint, so deployments that expose this endpoint and have cached URLs for deleted bundles are exposed. The provided data does not identify any configuration prerequisite beyond that behavior.
How can I determine whether deleted bundles may be affected?
Review whether deleted bundle URLs remain cached and can still be requested through the public file read endpoint. Successful retrieval of a deleted bundle, or restoration of its object into R2 after a cache hit, indicates exposure.
