CVE-2023-1904Network attack vector

OpenID client-secret exposure via clear-text logging

Published Dec 14, 2023 · Updated Sep 18, 2024

Sensitive information exposure in affected Octopus Server versions allows remote authenticated users to read an OpenID client secret from logs. The OpenID configuration path writes the client-secret value into diagnostic logs without redaction. Exposure requires an affected configuration event and access to retained server logs; the disclosed value is limited to the configured OpenID client credential.
