The plugin later outputs this value without escaping, so the injected script runs in the context of any site visitor who accesses an affected page, potentially enabling session hijacking, defacement, or traffic redirection.

The EPSS score of less than 1% suggests a low but non\u2011zero likelihood of exploitation at present, and the issue is not listed in the CISA KEV catalog.
