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. One may manually place code at the top of a view script where one calls the `formElementErrors()` view helper. More information about this workaround is available on the GitHub Security Advisory. https://getlaminas.org/security/advisory/LP-2022-01 https://github.com/laminas/laminas-form/commit/43005a3ec4c2292d4f825273768d9b884acbca37 https://github.com/laminas/laminas-form/security/advisories/GHSA-jq4p-mq33-w375
