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."}], "title": "Zakra <= 4.2.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Post Meta REST API", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/bbda67a3-0413-4d8e-8157-84c9c87b8695?source=cve"}, {"url": "https://themes.trac.wordpress.org/changeset?reponame=&new=330192%40zakra%2F4.2.1&old=297420%40zakra%2F4.2.0#file39"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')", "cweId": "CWE-79", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N", "baseScore": 6.4, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "Osvaldo Noe Gonzalez Del Rio (Os)"}], "timeline": [{"time": "2026-03-25T11:54:11.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-02T19:01:25.000Z", "lang": "en", "value": "Disclosed"}]}}}
