[dependabot]

Bumps loofah from 2.21.3 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

2.25.1 / 2026-03-17

• Ensure Loofah::HTML5::Scrub.allowed_uri? recognizes unescaped whitespace entities and rejects schemas containing them. See GHSA-46fp-8f5p-pf2m. #302 @​flavorjones

2.25.0 / 2025-12-15

• Extract Loofah::HTML5::Scrub.allowed_uri? which operates on a string. Previously this logic was coupled to the parsed tree in .scrub_uri_attribute. #300 @​flavorjones
• Tightened up how entities and control characters are handled when detecting allowed URIs. #301 @​flavorjones

2.24.1 / 2025-05-12

Ruby support

• Import only what's needed from cgi for support for Ruby 3.5 #296 @​Earlopain

Pull Request Overview

This PR attempts to resolve security vulnerabilities (GHSA-5qhf-9phg-95m2, etc.) by bumping 'loofah' to version 2.25.2. However, Codacy analysis indicates the PR is not up to standards due to 28 new security issues identified within the 'Gemfile.lock'. While 'loofah' is updated, critical dependencies such as 'nokogiri' and 'rack' remain pinned to versions containing high-severity memory management and denial-of-service vulnerabilities. These issues should prevent merging until the broader dependency tree is secured.

About this PR

• The Gemfile.lock diff is currently marked as excluded or was not fully visible during review. This prevents manual verification of the implementation. Given the high-severity vulnerabilities flagged in the lockfile, please ensure the bump to 2.25.2 is correctly applied alongside fixes for its dependencies.

1 comment outside of the diff

docs/multiple-tests/multi-patterns/src/Gemfile.lock

_{line 42 🔴 HIGH RISK}
Nokogiri version 1.15.3 contains a critical memory-related vulnerability (GHSA-353f-x4gh-cqq8) in the vendored libxml2. Updating to nokogiri >= 1.18.9 is required to resolve this. Use an IDE agent or run 'bundle update nokogiri' to patch this.

Test suggestions

• Verify that Gemfile.lock contains the correct version bump to 2.25.2
• Verify that existing HTML sanitization and scrubbing functionality remains operational with the new dependency version

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify that Gemfile.lock contains the correct version bump to 2.25.2
2. Verify that existing HTML sanitization and scrubbing functionality remains operational with the new dependency version
