Bump the bundler group across 1 directory with 4 updates

[dependabot]

Bumps the bundler group with 3 updates in the / directory: rails-html-sanitizer, mcp and websocket-driver.

Updates rails-html-sanitizer from 1.7.0 to 1.7.1

Release notes

Sourced from rails-html-sanitizer's releases.

v1.7.1 / 2026-07-15

• SVG reference elements now restrict both href and xlink:href to local references.

  Previously PermitScrubber restricted only xlink:href on elements in SVG_ALLOW_LOCAL_HREF, so a plain href attribute on those elements could reference an external document. Applications are only affected if the allowed tags are overridden to include an SVG reference element such as use; the default configuration is not affected.

  This change addresses GHSA-cj75-f6xr-r4g7 (CVE requested). The minimum Loofah dependency is now ~> 2.25, >= 2.25.2.

Updates loofah from 2.25.1 to 2.25.2

Release notes

Sourced from loofah's releases.

2.25.2 / 2026-07-15

Security

• Ensure Loofah::HTML5::Scrub.allowed_uri? recognizes numeric character references without semicolons (e.g. javascript&#58alert(1)), which browsers decode and execute, and rejects schemes split by them. See GHSA-5qhf-9phg-95m2. @​flavorjones
• Ensure Loofah::HTML5::Scrub.allowed_uri? recognizes the named character references 	 and 
, which CGI.unescapeHTML does not decode and browsers strip from URIs, and rejects schemes split by them (e.g. java	script:alert(1)). See GHSA-8whx-365g-h9vv. @​flavorjones
• Ensure that both href and xlink:href attributes on SVG elements like use are restricted to local (same-document) references. Previously only xlink:href was restricted, allowing the SVG 2 href attribute to reference external documents. See GHSA-9wjq-cp2p-hrgf. @​flavorjones

Improved

• Harden data: URI mediatype parsing in Loofah::HTML5::Scrub.allowed_uri?. The mediatype is now parsed following the WHATWG data: URL spec and RFC 2397 instead of simply being split on a colon. A data: URI with an omitted or malformed mediatype is now treated as text/plain and allowed, and one without the required comma is now rejected. #305 @​flavorjones
• Remove feed from the default set of allowed protocols. The feed URI scheme was never accepted as a standard protocol, and no major browser supports it. Removing it reduces the attack surface particularly for non-browser contexts. #304 @​flavorjones
• Remove a vestigial &#x70 alternative from Loofah::HTML5::SafeList::PROTOCOL_SEPARATOR. This appears to be an ancient typo dating back to pre-extraction Rails circa 2007. #305 @​flavorjones
