An authenticated attacker can place a victim tenant's image key in a row they control, causing the service-role worker to download and re-upload that object with sanitized metadata. Attackers can silently modify metadata in cross-tenant image objects by supplying known victim keys during authorized row updates, bypassing storage access controls through the confused-deputy metadata worker.","published":"2026-09-26T13:22:55.404Z","modified":"2026-09-26T13:22:55.404Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/Cap-go/capgo.app/security/advisories/GHSA-rcrw-pg2v-j9xg"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/capgo-before-12.244.1-cross-tenant-image-overwrite-via-metadata-worker"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-26T13:22:55.404Z"}}
