CVE-2021-47892Public exploitNetwork attack vector

Client-side script execution via unneutralized comments

Published Jan 23, 2026 · Updated Jan 23, 2026

Stored XSS in PEEL Shopping 9.3.0 allows remote attackers to execute JavaScript through purchase-page special instructions. The achat/achat_maintenant.php purchase handler persists the Comments / Special Instructions value and later renders it without neutralizing script markup. Submitting a purchase is the reachability gate; the payload runs when the stored purchase page is refreshed, enabling script actions in that browser context.
