  - jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true,     {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable
    __proto__ property, it could extend the native Object.prototype. (CVE-2019-11358)

  - In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option>     elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods     (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
    (CVE-2020-11023)

  - A denial of service vulnerability in the multipart parsing component of Rack fixed in 2.0.9.2, 2.1.4.2,     2.2.4.1 and 3.0.0.1 could allow an attacker tocraft input that can cause RFC2183 multipart boundary     parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack     vector. Any applications that parse multipart posts using Rack (virtually all Rails applications) are     impacted. (CVE-2022-44572)

  - A DoS vulnerability exists in Rack <v3.0.4.2, <v2.2.6.3, <v2.1.4.3 and <v2.0.9.3 within in the Multipart     MIME parsing code in which could allow an attacker to craft requests that can be abuse to cause multipart     parsing to take longer than expected. (CVE-2023-27530)
