An attacker can inject malicious script snippets that execute in the victim\u2019s browser when a crafted URL is visited. This can lead to session hijacking, cookie theft, defacement or other client-side attacks, as the flaw resides in the WordPress UpSolution Core plugin.", "risk_and_exploitability": "The CVSS score of 7.1 indicates a moderate-to-high risk level. Attackers can exploit the flaw simply by sending a crafted URL or payload to a site hosting the vulnerable plugin, without needing elevated privileges. Because the flaw is reflected in the browser and no authentication is needed, it can be used by anyone who can generate a link and lure a user to click. The EPSS information is currently unavailable, and the vulnerability is not listed in CISA\u2019s KEV catalog, but its high score and wide plugin usage make it a significant threat for active WordPress sites."}}}}, "created": "2026-03-25T21:34:27.484719+00:00", "updated": "2026-03-26T12:13:05.076991+00:00", "vendors": ["upsolution", "upsolution$PRODUCT$upsolution_core", "wordpress", "wordpress$PRODUCT$wordpress"]}
