GHSA-c76h-2ccp-4975 Use of Insufficiently Random Values in undici

• npm undici: >= 4.5.0, < 5.28.5 → fixed in 5.28.5 • npm undici: >= 6.0.0, < 6.21.1 → fixed in 6.21.1 • npm undici: >= 7.0.0, < 7.2.3 → fixed in 7.2.3

Impact Undici `fetch()` uses 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. Patches This is fixed in 5.28.5; 6.21.1; 7.2.3. Workarounds Do not issue multipart requests to attacker controlled servers.
