A subscriber or higher role can set this value in the plugin\u2019s settings. The value is then persisted in the database and later rendered into web pages without filtering, allowing an attacker to embed arbitrary JavaScript. When a victim user visits a page that includes this value, the injected script runs in the victim\u2019s browser, enabling cookie theft, session hijacking, defacement or execution of malicious actions on behalf of the user.", "risk_and_exploitability": "The CVSS score of 6.4 indicates a moderate severity vulnerability that can be exploited by any authenticated user with subscriber-level access, the lowest role that can configure the plugin. The materialization of the flaw does not require any network\u2011level exploits; it relies on legitimate credentials and platform access. EPSS is not available and the issue is not listed in the CISA KEV catalog, suggesting the attack probability is currently unclear, but the output results in cross\u2011site scripting and can lead to significant compromise of user sessions."}}}}, "created": "2026-04-16T05:30:25.679219+00:00", "updated": "2026-04-16T09:00:05.298804+00:00", "vendors": ["fahadmahmood", "fahadmahmood$PRODUCT$wp_docs", "wordpress", "wordpress$PRODUCT$wordpress"]}
