rails: Action View provides conventions and helpers for building web pages with the Rails framework
CVE-2026-33168 is fixed in rails on 1 platform, first by DEBIAN-CVE-2026-33168, released March 23, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Action View provides conventions and helpers for building web pages with the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when a blank string is used as an HTML attribute name in Action View tag helpers, the attribute escaping is bypassed, producing malformed HTML. A carefully crafted attribute value could then be misinterpreted by the browser as a separate attribute name, possibly leading to XSS. Applications that allow users to specify custom HTML attributes are affected. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
