What is CVE-2026-100614?
CVE-2026-100614 is a high-severity missing authorization vulnerability in Cap-go capgo.app, published on 26 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Capgo before 12.244.1 contains a cross-tenant integrity vulnerability in the metadata-cleaning worker that trusts image object keys from mutable database rows without validating ownership. 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.
