Angular is Vulnerable to XSRF Token Leakage via Protocol-Relative URLs in Angular HTTP Client

CVE-2025-66035 / GHSA-58c5-g7wp-6w37

More information

Details

The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain.

Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header.

Impact

The token leakage completely bypasses Angular's built-in CSRF protection, allowing an attacker to capture the user's valid XSRF token. Once the token is obtained, the attacker can perform arbitrary Cross-Site Request Forgery (CSRF) attacks against the victim user's session.

Attack Preconditions

1. The victim's Angular application must have XSRF protection enabled.
2. The attacker must be able to make the application send a state-changing HTTP request (e.g., POST) to a protocol-relative URL (e.g., //attacker.com) that they control.

Patches

• 19.2.16
• 20.3.14
• 21.0.1

Workarounds

Developers should avoid using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs.

@​angular/common: Denial of Service (DoS) via OOM in Date Formatting (formatDate)

CVE-2026-54268 / GHSA-48r7-hpm6-gfxm

More information

Details

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).

Impact

1. Server-Side Rendering (SSR)

In Angular applications that leverage Server-Side Rendering, an attacker can supply a malicious payload with an excessively long date format string. Processing this on the server causes high CPU usage and triggers a JavaScript heap out of memory crash, rendering the application unavailable to all users.

2. Client-Side Rendering (CSR)

In standard client-side applications, executing the vulnerable function with an excessively long format string blocks the browser's main thread, causing the browser tab to freeze and become completely unresponsive.

Patched Versions

• 22.0.1
• 21.2.17
• 20.3.25

Attack Preconditions

For this vulnerability to be exploitable, both of the following conditions must be met:

1. Vulnerable Component Usage: The application must format dates using the formatDate utility or the DatePipe.
2. Attacker-Controlled Parameter: The date format string passed to these utilities must be customizable or directly controlled by untrusted user input (e.g., parsed from query parameters, user preferences, or API responses).

If the date format is hardcoded (e.g., 'mediumDate', 'shortTime', or static strings) or properly validated to be within a reasonable length limit, the application is not vulnerable.

Severity

• CVSS Score: 8.2 / 10 (High)
• Vector String: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
