An attacker can embed such payloads in user\u2011controlled fields, such as link URLs or titles, that are read and displayed by the plugin. When a visitor loads the page containing the reflected content, the injected script runs in their browser and can steal credentials, hijack sessions, deface content, or carry out other client\u2011side attacks without needing elevated server privileges.", "risk_and_exploitability": "The base CVSS score of 7.1 indicates moderate to high severity and client\u2011side impact. An EPSS score of less than 1% shows that publicly documented exploitation attempts are exceedingly rare. The weakness is not listed in the CISA Known Exploited Vulnerabilities catalog. The attack vector is external: an attacker must supply crafted input, typically via URLs or form submissions, that is subsequently reflected in the page. No public exploit code is known, but the reflected nature of the XSS makes it simple for an attacker who can persuade a victim to click a malicious link."}}}}, "created": "2026-02-23T14:36:17.662985+00:00", "updated": "2026-04-16T16:45:25.959167+00:00", "vendors": ["spencer_haws", "spencer_haws$PRODUCT$link_whisper_free", "wordpress", "wordpress$PRODUCT$wordpress"]}
