The attack vector is most likely through a CSRF request made by a logged\u2011in administrator or other privileged user; the attacker would need to persuade the victim to visit a crafted URL or submit a crafted form while authenticated. The absence of an immediate patch notice means site owners should treat the issue as serious and remediate promptly."}}}}, "created": "2026-04-08T19:29:21.530622+00:00", "updated": "2026-04-14T16:41:30.035845+00:00", "vendors": ["mndpsingh287", "mndpsingh287$PRODUCT$theme_editor", "wordpress", "wordpress$PRODUCT$wordpress"]}
