Authenticated contributors or higher can embed arbitrary JavaScript into page elements. When any visitor loads the affected page, the injected script runs in their browser, enabling attackers to steal session tokens, deface content, or phish for credentials.

The EPSS score, currently less than 1%, indicates a low probability of exploitation, and the flaw is not listed in the CISA KEV catalog.

The stored nature of the payload means the impact depends on who views the page, making the risk significant for sites with many visitors but limited to those who accrue contributor privileges."}}}}, "created": "2025-12-18T09:57:09.593361+00:00", "updated": "2026-04-21T00:45:23.101773+00:00", "vendors": ["livecomposer", "livecomposer$PRODUCT$live_composer", "wordpress", "wordpress$PRODUCT$wordpress"]}
