The flaw stems from missing nonce validation and a lack of file\u2011type checks, so a malicious request can be dispatched to the server and any file placed on the webroot. If the attacker manages to get a site administrator to follow a crafted link, the uploaded file could be executed, enabling remote code execution on the host.", "risk_and_exploitability": "The flaw has a CVSS score of 8.8, indicating high severity. The EPSS score is under 1% and the issue is not listed in the CISA KEV catalog, suggesting exploitation is not yet widespread. The attack vector is a web\u2011based CSRF: an attacker must induce an authenticated administrator to visit a crafted URL or submit a forged form to trigger a file upload. If successful, the attacker could upload a malicious payload that later executes with the privileges of the web server. Given the systemic nature of the impact, the risk remains significant despite the low exploitation probability."}}}}, "created": "2025-11-24T09:08:02.173671+00:00", "updated": "2026-04-27T23:00:13.962805+00:00", "vendors": ["wordpress", "wordpress$PRODUCT$wordpress", "zozothemes", "zozothemes$PRODUCT$zegen"]}
