According to its self-reported version number, Angular is prior to 20.0.0, 20.x prior to 20.3.27, 21.x prior to 21.2.19 or 22.x prior to 22.0.1. It is, therefore, affected by multiple vulnerabilities:

- A Cross-Site Scripting (XSS) vulnerability in the internationalization (i18n) pipeline of @angular/compiler. Event-handler attributes (such as onerror) can be marked for translation using i18n-on* attributes, allowing a malicious translation file to inject arbitrary JavaScript in the localized build. (CVE-2026-69151)

- An information disclosure vulnerability in @angular/service-worker. Sensitive request headers (such as Authorization) are not stripped on cross-origin redirects, allowing a remote attacker to obtain credentials by triggering a redirect to an untrusted origin. (CVE-2026-54264)

- A denial of service vulnerability in the formatDate function of @angular/common, also used by DatePipe. The length of the format parameter is not validated, allowing an excessively long format string to cause uncontrolled CPU and memory consumption. (CVE-2026-54268)

- A DOM clobbering vulnerability in the client hydration of @angular/core. The serialized transfer state is looked up using the predictable ng-state element identifier, allowing an attacker able to inject an element with this identifier to poison the hydration response cache. (CVE-2026-54267)

- A weak cache key hashing vulnerability in the HttpTransferCache of @angular/common. Cache keys are generated with a 32-bit hash, allowing an attacker to craft colliding request parameters so that an attacker-controlled response overwrites the response of a sensitive endpoint during SSR, leading to data leakage or state poisoning. (CVE-2026-54266)

- A sanitization bypass vulnerability in @angular/compiler. Security-sensitive native DOM properties (such as innerHTML, src or href) bound using the two-way binding syntax are emitted without sanitizer, leading to Cross-Site Scripting (XSS). (CVE-2026-54265)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Angular is a development platform for building mobile and desktop web applications using
    TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, a Denial of Service
    (DoS) vulnerability exists in the @angular/common package of the Angular framework. The formatDate
    function, which is also utilized by the standard Angular DatePipe, does not properly limit or validate the
    length of the format parameter. When parsing a maliciously crafted, excessively long date format string
    (e.g., a repeating pattern or very large string), the internal parser splits the string iteratively using
    a regular expression loop. This results in uncontrolled resource consumption (high CPU utilization and
    excessive memory allocations), leading to a Denial of Service (DoS). This vulnerability is fixed in
    22.0.1, 21.2.17, and 20.3.25. (CVE-2026-54268)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus relies on the presence of the package as reported by the vendor.
