Technical details
The vulnerability stems from improper validation of the sysType field in sa-token sessions, allowing storefront customers to reuse their authentication tokens to access back-office endpoints that lack @PreAuthorize permission checks. An authenticated customer on the public storefront can directly request admin endpoints (menu listings, file uploads, configuration) by presenting their valid session token. No patch information is available in the advisory.
