SCA: security update for rails-html-sanitizer (GHSA-cj75-f6xr-r4g7)
medium Tenable Cloud Security Plugin ID 445033
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. From 1.0.3 until
1.7.1, Rails::HTML::PermitScrubber restricted SVG reference elements in SVG_ALLOW_LOCAL_HREF only when
they used xlink:href, even though browsers also accept the plain href attribute. Applications with non-
default allowed tags that included SVG use or feImage elements could therefore permit external references;
a same-origin external SVG referenced by use could execute scripts in the sanitized document's context,
while feImage could load external images for tracking. Applications using the default allowed tags are not
affected. This issue is fixed in version 1.7.1. (CVE-2026-73648)
Solution
Update the rails-html-sanitizer library and its related packages to version 1.7.1 or later.See Also
