Action View: Possible XSS vulnerability in strip_tags

CVE-2026-126070

Impact striptags in Action View returns its sanitized output marked htmlsafe, but the underlying sanitizer encodes only &, , leaving " and ' unencoded. Because ERB does not escape a string marked htmlsafe, untrusted input passed through striptags and rendered inside a quoted HTML attribute value could close the attribute and add new attributes, possibly leading to XSS. Applications that render striptags output from untrusted input inside an HTML attribute, for example in a title attribute or a tag, are affected. Output rendered as element content is not affected. Details striptags now encodes " and ' in its output, as well as &, , without double-encoding existing entities. Applications that use striptags output outside HTML, such as in a text template or JSON, now see " and ' where they saw " and '; CGI.unescapeHTML decodes them. See the Action View CHANGELOG. Workarounds Pass striptags output to an attribute through a tag helper, which escapes attribute values, for example tag.a(title: striptags(userinput)).
