Dependency overwrite via MD5 path collision
Published Apr 23, 2025 · Updated Apr 23, 2025
Weak hashing in pnpm before 10.0.0 allows remote attackers to overwrite indirect dependencies through crafted package paths. The depPathToFilename function truncates long normalized dependency paths and appends an MD5-derived suffix, so distinct packages can resolve to the same store directory. Exploitation requires attacker-chosen package identifiers with a shared retained prefix and colliding hashes; the dependency installed later determines the version used.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
