An attacker with Contributor or higher privileges can craft a malicious value for the class attribute, which the plugin concatenates into the HTML output without escaping. The result is stored XSS; when any user visits a page containing the injected shortcode, the malicious script runs in that user\u2019s browser, potentially leading to defacement, session hijacking, or the delivery of phishing payloads. This attack does not compromise the server directly but can compromise the confidentiality, integrity, and authenticity of all site users who access the affected pages.", "risk_and_exploitability": "The CVSS score of 6.4 reflects a moderate impact, and the EPSS score is not available, so the probability of exploitation in the wild is unclear.

If such users are present on the site, the risk remains present until the plugin is upgraded or the usage of the affected shortcode is removed."}}}}, "created": "2026-04-08T19:44:04.141389+00:00", "updated": "2026-04-09T08:22:23.833386+00:00", "vendors": ["realmag777", "realmag777$PRODUCT$tableon_\u2013_wordpress_posts_table_filterable", "wordpress", "wordpress$PRODUCT$wordpress"]}
