AI risk analysis

Summary: The flaw allows an authenticated attacker to modify metadata in cross-tenant image objects by supplying known victim keys, bypassing storage access controls.
Exploitability: Exploitation requires an authenticated attacker with control over a mutable database row and knowledge of the victim's key. This is moderately hard to exploit.
Blast radius: If exploited, the vulnerability could lead to silent modification of metadata in cross-tenant image objects, potentially compromising data integrity.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Capgo 12.244.1 or later.

NVD 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.
