Low risk25th percentile - higher than 25% of all known CVEs
Summary
In Angular (@angular/common) prior to versions 22.0.1, 21.2.17, and 20.3.25, a DoS vulnerability exists. The formatDate function and DatePipe do not limit the length of the format parameter, allowing CPU and memory exhaustion via a maliciously long format string.
Risk Assessment
An attacker can remotely overload the Angular application server, causing service unavailability. High CPU and memory consumption may lead to operational costs and downtime.
Recommendation
Immediately update Angular to version 22.0.1, 21.2.17, or 20.3.25 depending on your branch. If updating is not possible, restrict access to formatDate and DatePipe for untrusted input.
Original NVD description (English source)
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.
