CVE-2026-69151

Angular prior to versions 20.3.27, 21.2.19, and 22.0.7 contains a Cross-Site Scripting (XSS) vulnerability in @angular/platform-server's DOM emulation dependency (domino) when serializing the content of fallback raw-content elements (<iframe>, <noembed>, <noframes>, and <noscript>).

Angular prior to versions 20.3.27, 21.2.19, and 22.0.2 contains a vulnerability in HttpTransferCache that comma-joins repeated request parameters. This allows semantically distinct HttpClient requests to use the same transfer-cache key and reuse a wrong backend response.

A Cross-Site Scripting (XSS) vulnerability exists in Angular's @angular/platform-server component when serializing <noscript> elements during SSR. The domino library fails to escape </noscript> in dynamic content, allowing injection of malicious scripts.

A Cross-Site Scripting (XSS) vulnerability exists in Angular's @angular/platform-server DOM emulation dependency (domino) when serializing raw-text elements like <script>, <style>, and <iframe>. A Unicode index alignment bug causes dynamic text with astral characters (e.g., emojis) before a closing tag to be improperly escaped, allowing JavaScript injection. The flaw is fixed in versions 22.0.0-rc.2, 21.2.16, 20.3.24, and 19.2.25.

A DOM Clobbering vulnerability in Angular allows an attacker to replace the SSR state container (ng-state) by injecting an HTML element with the same ID. During client hydration, Angular reads data from the fake element, potentially leading to code execution or data theft.

A vulnerability in Angular prior to versions 22.0.1, 21.2.17, and 20.3.25 allows an attacker to overwrite HTTP responses in the TransferState cache during Server-Side Rendering (SSR). The weak 32-bit DJB2 hash used for cache key generation enables hash collisions, causing sensitive endpoint responses to be replaced with responses from other requests.

A vulnerability in Angular's @angular/compiler and @angular/core packages allows bypassing element and attribute sanitization via namespace workarounds. An attacker can inject a malicious template with custom namespaces, leading to client-side Cross-Site Scripting (XSS).

An XSS vulnerability in the Angular i18n pipeline allows arbitrary JavaScript execution if an attacker compromises the translation file. Affects versions prior to 21.2.0, 21.1.16, 20.3.17, and 19.2.19 due to unsanitized HTML in ICU messages.

This vulnerability affects angular package versions from 1.3.0 and angularjs package versions from 1.3.0. A regular expression used to split the value of the ng-srcset directive is vulnerable to catastrophic backtracking, leading to super-linear runtime. With large crafted input, this can cause a denial of service (DoS). The package is End-of-Life (EOL) and will not receive fixes.
