CVE-2026-100622: Exposure of Sensitive Information to an Unauthorized Actor in Cap-go capgo.app
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.
AI Analysis
Technical Summary
The vulnerability in capgo.app (versions up to 12.129.0) involves improper verification of deletion status when serving cached bundle artifacts from the public file read endpoint. Attackers without authentication can exploit this flaw to access deleted bundles by using cached URLs. Additionally, this triggers the restoration of deleted objects back into R2 storage upon cache hits, exposing sensitive information that should have been removed.
Potential Impact
Unauthenticated attackers can access and download deleted bundles that should no longer be available, resulting in exposure of sensitive information. The restoration of deleted objects into storage increases the risk of data leakage and undermines data deletion guarantees.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
