Capgo before 12.244.1 Cross-Tenant Image Overwrite via Metadata Worker

Published Sep 26, 2026 · Updated Sep 28, 2026 · Assigned by VulnCheck

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.
