SB2026092387 - Resource exhaustion in Angular

Description

This security bulletin contains information about 1 vulnerability.

1) Resource exhaustion (CVE-ID: N/A)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.2 [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]

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in @angular/router when parsing request URLs with numeric matrix parameter names. A remote attacker can send concurrent crafted requests containing repeated numeric matrix parameters to cause a denial of service.

Exploitation requires a Node.js/V8 server-side rendering deployment in which upstream proxies forward semicolon-containing, multi-segment URLs.
