CVE-2026-1866Network attack vector

Stored XSS via double HTML-entity decoding

Published Feb 10, 2026 · Updated Feb 10, 2026

Stored XSS in Jeroen Peters Name Directory 1.32.0 and earlier allows remote attackers to inject scripts through public submissions. The submission sanitizer decodes HTML entities before wp_kses filters the name and description, then decodes the filtered output again and restores executable markup. Script execution requires administrator approval unless auto-publish is enabled, and it occurs when a user visits the page containing the approved entry.
