Description

A regular expression used by AngularJS'  linky https://docs.angularjs.org/api/ngSanitize/filter/linky  filter to detect URLs in input text is vulnerable to super-linear runtime due to backtracking. With a large carefully-crafted input, this can cause a Regular expression Denial of Service (ReDoS) https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_-_ReDoS  attack on the application. This issue affects all versions of AngularJS. Note: The AngularJS project is End-of-Life and will not receive any updates to address this issue. For more information see here https://docs.angularjs.org/misc/version-support-status .
