An attacker can embed malicious JavaScript code into the URL that the plugin echoes back to the page. Because no authentication is required, any user who clicks a crafted link could have arbitrary script executed in their browser.", "risk_and_exploitability": "The CVSS score of 6.1 indicates moderate severity, and the EPSS score of less than 1% suggests that exploitation is unlikely to be widespread, although it is not excluded from being exploited in targeted attacks. Because the vulnerability requires only a crafted link and is triggered on the victim\u2019s browser, the attack vector is essentially phishing or social engineering. The Impact is confined to the victim\u2019s browser session, enabling credential theft, session hijacking, or defacement. The vulnerability is not currently listed in CISA\u2019s KEV catalog, so no mandatory mitigation is mandated, but remediation is recommended."}}}}, "created": "2025-12-08T09:39:40.778125+00:00", "updated": "2026-04-22T16:30:22.139785+00:00", "vendors": ["wordpress", "wordpress$PRODUCT$wordpress"]}
