What is CVE-2026-100614?

Capgo versions before 12.244.1 exhibit a cross-tenant integrity vulnerability that arises in the metadata-cleaning worker. This flaw allows authenticated attackers to exploit the system by inserting a victim tenant's image key into a controllable database row. The service role worker, failing to validate ownership, subsequently downloads and re-uploads this image with altered metadata. Consequently, attackers can covertly modify metadata associated with cross-tenant imagery, effectively circumventing established storage access controls through the role of a confused-deputy metadata worker.
