Doc Text:	A flaw was found in AngularJS. The Strict Contextual Escaping (SCE) logic, designed to ensure only trusted values are used in security-sensitive contexts like resource URLs, can be bypassed. This bypass allows an attacker to use unsafe values as resource URLs, leading to arbitrary JavaScript execution within the victim's browser session. This could result in information disclosure or other impacts depending on the executed script.	Story Points:	---

Description OSIDB Bzimport 2026-06-24 22:02:51 UTC

A flaw in AngularJS' Strict Contextual Escaping (SCE) logic allows bypassing certain SCE policies for resource URLs and can lead to arbitrary JavaScript execution within the context of the victim's browser session.


SCE's purpose is to ensure that only trusted or safe values are used in certain security-sensitive contexts, such as resource URLs, including URLs that define executable JavaScript scripts, '<iframe>' documents, route templates, etc. A flaw in the logic that tries to match entire URLs against regular expression matchers can result in partial matches for certain types of regular expressions, effectively bypassing the policies and allowing the use of unsafe values as resource URLs.


This issue affects AngularJS versions greater than or equal to 1.2.0-rc.3.


Note:
The AngularJS project was already End-of-Life when this CVE was published and will not receive any updates to address this issue. For more information see the  End-of-Life announcement https://docs.angularjs.org/misc/version-support-status .
