- CWE-1333 - Inefficient Regular Expression Complexity
Summary
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 .
