Unauthenticated attachment deletion via flawed guest ownership validation
Published Feb 19, 2026 · Updated Feb 19, 2026
Authorization bypass in QuadLayers Checkout Field Manager 7.8.5 and earlier allows remote attackers to delete guest-order attachments. The attachment-deletion handler accepts a public wooccm_upload nonce and attachment ID while an inverted login check and missing order-key validation fail to establish guest ownership. No account or user interaction is required; successful requests remove guest-order media without granting read access or broader site control.
