CVE-2026-40791Public exploitNetwork attack vector

Admin-context script execution via unescaped booking slot

Published Jun 15, 2026 · Updated Jun 15, 2026

Stored XSS in CodePeople WP Time Slots Booking Form 1.2.46 and earlier allows remote attackers to run scripts in an administrator's browser. The booking parser preserves a tab-delimited SVG payload in the stored slot value, which Booking Orders emits into HTML without escaping. No account is required, but an administrator must view the malicious booking before its script can act with that browser session's site privileges.
