Published Sep 26, 2026

Updated

Cap-go capgo.app before 12.267.1 fails to validate target API key privilege during rotation, allowing an apikeymanager to rotate a higher-privileged orgsuperadmin sibling key and recover its plaintext credential. Attackers with apikeymanager role can enumerate same-owner API keys, rotate a stronger sibling through the PUT endpoint, and obtain the replacement plaintext secret to authenticate as the higher-privileged principal.
