CVE-2025-22150
CVSS v3.1
6.8
Medium
| Vector | AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N |
Name of the Vulnerable Software and Affected Versions
undici versions 4.5.0 through 5.28.4
undici versions 4.5.0 through 6.21.0
undici versions 4.5.0 through 7.2.2
Description
The issue arises from undici using
Math.random() to choose the boundary for a multipart/form-data request. It is known that the output of Math.random() can be predicted if several of its generated values are known. If there is a mechanism in an app that sends multipart requests to an attacker-controlled website, they can use this to leak the necessary values. Therefore, an attacker can tamper with the requests going to the backend APIs if certain conditions are met.Recommendations
For undici versions 4.5.0 through 5.28.4, update to version 5.28.5 or later.
For undici versions 4.5.0 through 6.21.0, update to version 6.21.1 or later.
For undici versions 4.5.0 through 7.2.2, update to version 7.2.3 or later.
As a temporary workaround, do not issue multipart requests to attacker-controlled servers.
