The risk materializes only when allow_url_fopen is enabled, the public post\u2011creation form is active, and that form contains a file\u2011upload field. Sites that have disabled the form or turned off allow_url_fopen are not directly exploitable.", "description_and_impact": "The plugin omits file\u2011type checks in copy_post_image(), letting any file be stored on the server. An unauthenticated attacker can then place executable code or other malicious files, creating a pathway to remote code execution. The flaw is a classic file\u2011upload vulnerability (CWE\u2011434).", "risk_and_exploitability": "The severity is high with a CVSS score of 9.8, but the EPSS score of <1% indicates that exploitation is presently unlikely on a large scale, and the vulnerability is not listed in the CISA KEV catalog. Because the flaw is user\u2011controlled and requires no authentication, the attack vector is likely a simple HTTP request to the front\u2011end form, potentially accompanied by a crafted URL that injects a malicious file. Enforcing proper file\u2011type validation would close the window for malicious uploads."}}}}, "created": "2025-11-07T10:53:36.005796+00:00", "updated": "2026-04-22T12:15:16.042925+00:00", "vendors": ["gravityforms", "gravityforms$PRODUCT$gravity_forms", "wordpress", "wordpress$PRODUCT$wordpress"]}
