CVE-2023-30528Network attack vector

Client secret exposure via unmasked configuration field

Published Apr 12, 2023 · Updated Feb 7, 2025

Credential exposure in Jenkins WSO2 Oauth Plugin 1.0 and earlier allows remote authenticated users to capture its OAuth client secret. The global configuration form renders the stored WSO2 OAuth client secret without password masking, leaving its value visible instead of replacing it with asterisks. Access to the protected configuration form and an opportunity to observe its display are required; no integrity or availability impact is reported.
