CVE-2021-26540

Apostrophe Technologies sanitize-html before 2.3.2 does not properly validate the hostnames set by the "allowedIframeHostnames" option when the "allowIframeRelativeUrls" is set to true, which allows attackers to bypass hostname whitelist for iframe element, related using an src value that starts with "/\example.com".

CVE-2021-26539

Apostrophe Technologies sanitize-html before 2.3.1 does not properly handle internationalized domain name (IDN) which could allow an attacker to bypass hostname whitelist validation set by the "allowedIframeHostnames" option.

Release Notes

apostrophecms/sanitize-html (sanitize-html)

v2.3.2

Compare Source

• Additional fixes for iframe validation exploits. Prevent exploits based on browsers' tolerance of the use of "" rather than "/" and the presence of whitespace at this point in the URL. Thanks to Ron Masas of Checkmarx for pointing out the issue and writing unit tests.
• Updates README yarn add syntax. Thanks to Tagir Khadshiev for the contribution.

v2.3.1

Compare Source

• Uses the standard WHATWG URL parser to stop IDNA (Internationalized Domain Name) attacks on the iframe hostname validator. Thanks to Ron Masas of Checkmarx for pointing out the issue and suggesting the use of the WHATWG parser.

v2.3.0

Compare Source

• Upgrades htmlparser2 to new major version ^6.0.0. Thanks to Bogdan Chadkin for the contribution.

v2.2.0

Compare Source

• Adds a note to the README about Typescript support (or the lack-thereof).
• Adds tel to the default allowedSchemes. Thanks to Arne Herbots for this contribution.

v2.1.2

Compare Source

• Fixes typos and inconsistencies in the README. Thanks to Eric Lefevre-Ardant for this contribution.

v2.1.1

Compare Source

• Fixes a bug when using allowedClasses with an '*' wildcard selector. Thanks to Clemens Damke for this contribution.
• Updates mocha to 7.x to resolve security warnings.

v2.1.0

Compare Source

• sup added to the default allowed tags list. Thanks to Julian Lam for the contribution.
• Updates default allowedTags README documentation. Thanks to Marco Arduini for the contribution.

v2.0.0

Compare Source

• nestingLimit option added.
• Updates ESLint config package and fixes warnings.
• Upgrade is-plain-object package with named export. Thanks to Bogdan Chadkin for the contribution.
• Upgrade postcss package and drop Node 11 and Node 13 support (enforced by postcss).

Backwards compatibility breaks:

• There is no build. You should no longer directly link to a sanitize-html file directly in the browser as it is using modern Javascript that is not fully supported by all major browsers (depending on your definition). You should now include sanitize-html in your project build for this purpose if you have one.
• On the server side, Node.js 10 or higher is required.
• The default allowedTags array was updated significantly. This mostly added HTML tags to be more comprehensive by default. You should review your projects and consider the allowedTags defaults if you are not already overriding them.

v1.27.5

Compare Source

• Updates README to include ES modules syntax.

v1.27.4

Compare Source

• Fixes an IE11 regression from using Array.prototype.includes, replacing it with Array.prototype.indexOf.

v1.27.3

Compare Source

• Fixes a bug when using transformTags with out textFilter. Thanks to Andrzej Porebski for the help with a failing test.

v1.27.2

Compare Source

• Fixes CHANGELOG links. Thanks to Alex Mayer for the contribution.
• Replaces srcset with parse-srcset. Thanks to Massimiliano Mirra for the contribution.

v1.27.1

Compare Source

• Removes the unused chalk dependency.
• Adds configuration for a Github stale bot.
• Replace xtend package with native Object.assign.

v1.27.0

Compare Source

• Adds the allowedIframeDomains option. This works similar to allowedIframeHostnames, where you would set it to an array of web domains. It would then permit any hostname on those domains to be used in iframe src attributes. Thanks to Stanislav Kravchenko for the contribution.

v1.26.0

Compare Source

• Adds the option element to the default nonTextTagsArray of tags with contents that aren't meant to be displayed visually as text. This can be overridden with the nonTextTags option.

v1.25.0

Compare Source

• Adds enforceHtmlBoundary option to process code bounded by the html tag, discarding any code outside of those tags.
• Migrates to the main lodash package from the per method packages since they are deprecated and cause code duplication. Thanks to Merceyz for the contribution.
• Adds a warning when style and script tags are allowed, as they are inherently vulnerable to being used in XSS attacks. That warning can be disabled by including the option allowVulnerableTags: true so this choice is knowing and explicit.

v1.24.0

Compare Source

• Fixes a bug where self-closing tags resulted in deletion with disallowedTagsMode: 'escape' set. Thanks to Thiago Negri for the contribution.
• Adds abbr to the default allowedTags for better accessibility support. Thanks to Will Farrell for the contribution.
• Adds a mediaChildren property to the frame object in custom filters. This allows you to check for links or other parent tags that contain self-contained media to prevent collapse, regardless of whether there is also text inside. Thanks to axdg for the initial implementation and Marco Arduini for a failing test contribution.
