Official description

Capgo before 12.128.2 contains an authorization bypass vulnerability in the public.manifest INSERT policy that allows read-only org members to insert OTA manifest rows. Attackers with read-only org access can inject malicious manifest entries with arbitrary s3_path values that are served to devices via the unauthenticated /updates endpoint, enabling OTA metadata poisoning and potential malicious asset delivery.
