What is CVE-2025-22150?

The Undici HTTP/1.1 client, prior to specified patched versions, utilizes Math.random() to designate boundaries for multipart/form-data requests. This method is inherently flawed, as outputs can be predicted if previous values are exposed. Consequently, should an application dispatch multipart requests to a malicious server, an attacker could manipulate the transmitted data, leading to potential exploits against backend APIs. Users are urged to upgrade to versions 5.28.5, 6.21.1, or 7.2.3, or to avoid sending multipart requests to untrusted servers to mitigate risks.

Affected Version(s)

undici >= 4.5.0, < 5.28.5 < 4.5.0, 5.28.5

undici >= 6.0.0, < 6.21.1 < 6.0.0, 6.21.1

undici >= 7.0.0, < 7.2.3 < 7.0.0, 7.2.3
