This advisory covers the 1.20.3 release of Red Hat OpenShift Pipelines Operator which addresses several security issues including CVE-2025-11621.

No official patch or fix is currently available for these vulnerabilities as per the vendor advisory. Red Hat scores the severity as high and notes that mitigation options are either unavailable or insufficient by their standards.
