CVE-2022-23598: Fedoraproject Fedora

Medium severity, CVSS 6.1. EPSS: 1% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 34 only; version 35 only
• Getlaminas Laminas-Form: before 2.17.1 (fixed in 2.17.1); from 3.0.0, before 3.0.2 (fixed in 3.0.2); version 3.1.0 only
