This is due to the theme registering three post meta fields (zakra_menu_item_color, zakra_menu_item_hover_color, and zakra_menu_item_active_color) with 'show_in_rest' => true and 'auth_callback' => '__return_true', but without any sanitize_callback parameter in the register_post_meta() calls. While the classic editor save path applies sanitize_hex_color() sanitization, the REST API path completely bypasses this protection. The unsanitized meta values are then retrieved via get_post_meta() and concatenated directly into CSS strings that are output through wp_add_inline_style() without any escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the injected page."},{"lang":"es","value":"El tema Zakra para WordPress es vulnerable a cross-site scripting almacenado a través de valores meta de publicación en todas las versiones hasta, e incluyendo, la 4.2.0. Esto se debe a que el tema registra tres campos meta de publicación (zakra_menu_item_color, zakra_menu_item_hover_color y zakra_menu_item_active_color) con ’show_in_rest’ => true y ’auth_callback’ => ’__return_true’, pero sin ningún parámetro sanitize_callback en las llamadas a register_post_meta(). Mientras que la ruta de guardado del editor clásico aplica la sanitización sanitize_hex_color(), la ruta de la API REST omite completamente esta protección. Los valores meta no sanitizados son luego recuperados a través de get_post_meta() y concatenados directamente en cadenas CSS que se emiten a través de wp_add_inline_style() sin ningún escape. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a la página inyectada."}],"id":"CVE-2026-4804","lastModified":"2026-10-25T21:10:00.770","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":6.4,"baseSeverity":"MEDIUM","confidentialityImpact":"LOW","integrityImpact":"LOW","privilegesRequired":"LOW","scope":"CHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"exploitabilityScore":3.1,"impactScore":2.7,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-4804","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2026-07-06T16:25:36.489784Z","version":"2.0.3"}}]},"published":"2026-07-03T09:16:37.520","references":[{"source":"security@wordfence.com","url":"https://themes.trac.wordpress.org/changeset?reponame=&new=330192%40zakra%2F4.2.1&old=297420%40zakra%2F4.2.0#file39"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/bbda67a3-0413-4d8e-8157-84c9c87b8695?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-79"}],"source":"security@wordfence.com","type":"Secondary"}]}
