Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The openmetadata-service Maven package is affected in versions before 1.2.4. An authenticated non-admin user can call the policy validation condition endpoint with a crafted SpEL expression, which is evaluated without authorization checks and can run arbitrary system commands on the server. Upgrade to version 1.2.4, which is the fixed release.
