Because the plugin fails to sanitize or escape these inputs, an authenticated user with Contributor level access or higher can insert arbitrary JavaScript that will run in the browsers of anyone who views a page containing the injected shortcode. This vulnerability permits attackers to execute client\u2011side code in the context of the site, enabling session hijacking, defacement, or the delivery of additional malicious payloads.", "risk_and_exploitability": "The CVSS score of 6.4 indicates a medium severity, and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires an authenticated Contributor or better, making the attack vector internal. Once a shortcode is injected, the stored payload remains until the content is edited or the plugin is updated. Because the threat relies on user privileges, sites that limit Contributor access or use the latest version are less exposed. Nonetheless, if an attacker compromises a contributor account, the risk is significant for the affected website."}}}}, "created": "2026-04-09T08:15:46.103694+00:00", "updated": "2026-04-09T08:25:12.782029+00:00", "vendors": ["photoweblog", "photoweblog$PRODUCT$osm_\u2013_openstreetmap", "wordpress", "wordpress$PRODUCT$wordpress"]}
