CVE-2026-29175Public exploitNetwork attack vector

Session hijacking via unencoded inventory fields

Published Mar 10, 2026 · Updated Mar 10, 2026

Stored XSS in Pixel & Tonic Craft Commerce 5.0.0 through 5.5.2 allows remote authenticated users to hijack control-panel sessions. InventoryController passes product and variant descriptions and SKUs to HTML-generating helpers without encoding their values. An attacker needs control-panel, Commerce, and product-edit permissions; the payload runs when another user views inventory and can exfiltrate unmasked session cookies.
