apostrophecms/sanitize-html

'sanitize-html' prior to version 1.0.3 is vulnerable to Cross-site Scripting (XSS). The function 'naughtyHref' doesn't properly validate the hyperreference (`href`) attribute in anchor tags (`<a>`), allowing bypasses that contain different casings, whitespace characters, or hexadecimal encodings.

`sanitize-html` prior to version 2.0.0-beta is vulnerable to Cross-site Scripting (XSS). The `sanitizeHtml()` function in `index.js` does not sanitize content when using the custom `transformTags` option, which is intended to convert attribute values into text. As a result, malicious input can be transformed into executable code.

Versions of the package sanitize-html before 2.12.1 are vulnerable to Information Exposure when used on the backend and with the style attribute allowed, allowing enumeration of files in the system (including project dependencies). An attacker could exploit this vulnerability to gather details about the file system structure and dependencies of the targeted server.

The package sanitize-html before 2.7.1 are vulnerable to Regular Expression Denial of Service (ReDoS) due to insecure global regular expression replacement logic of HTML comment removal.

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.

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".

Sanitize-html is a library for scrubbing html input of malicious values. Versions 1.11.1 and below are vulnerable to cross site scripting (XSS) in certain scenarios: If allowed at least one nonTextTags, the result is a potential XSS vulnerability.
