CVE-2022-0954Public exploitNetwork attack vector

Stored XSS via unrestricted option-group sanitization bypass

Published Mar 15, 2022 · Updated Aug 2, 2024

Stored XSS in Microweber before 1.2.11 allows remote authenticated users to execute script through crafted shop settings. The SaveOptionApiController trusts option keys that disable XSS cleaning without first restricting them to the website option group, so injected markup can be stored through shop option groups. Exploitation requires privileged settings access and a victim to open an affected settings view, where the script runs in that victim's browser context.
