CVE-2022-23598 – Reflected XSS vulnerability when rendering error messages in laminas-form

https://notcve.org/view.php?id=CVE-2022-23598

28 Jan 2022 — laminas-form is a package for validating and displaying simple and complex forms. When rendering validation error messages via the `formElementErrors()` view helper shipped with laminas-form, many messages will contain the submitted value. However, in laminas-form prior to version 3.1.1, the value was not being escaped for HTML contexts, which could potentially lead to a reflected cross-site scripting attack. Versions 3.1.1 and above contain a patch to mitigate the vulnerability. A workaround is available. • https://getlaminas.org/security/advisory/LP-2022-01 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
