CVE-2025-4690 | AngularJS 'linky' filter ReDoS

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 .

4.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
