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 .

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
