Detailsinfo

A vulnerability was found in pnpm up to 9.x. It has been declared as problematic. Affected by this vulnerability is some unknown functionality of the file /node_modoules/ of the component MD5 Handler. The manipulation with an unknown input leads to a weak hash vulnerability. The CWE definition for the vulnerability is CWE-328. The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

pnpm is a package manager. Prior to version 10.0.0, the path shortening function uses the md5 function as a path shortening compression function, and if a collision occurs, it will result in the same storage path for two different libraries. Although the real names are under the package name /node_modoules/, there are no version numbers for the libraries they refer to. This issue has been patched in version 10.0.0.
