The company that makes enterprise software and cloud computing software sent out a special security alert on March 19 for the new problem, which is now known as CVE-2026-21992.
It affects the Oracle Identity Manager (OIM) and Oracle Web Services Manager (OWSM). The severity is clear right away because it lets remote code execution (RCE) happen and doesn't need authentication to do so. Attackers could use CVE-2026-21992 to change the identities, roles, and policies that an organization sets up through OIM. This could help them move around and gain more access to those organizations' networks.
They could also change or turn off the security rules that businesses set up in OWSM, which would make it easier for other bad cyber activity to happen.
