Arbitrary file access via incomplete path blocklist
Published May 12, 2026 · Updated May 12, 2026
Path traversal in Pulpy before 0.1.1 allows remote attackers to read and write user files through a packaged web application. The validateFsPath() function canonicalizes a requested path but rejects only a short list of root-level prefixes, so home-directory paths pass to pulpy.fs read and write methods. Exploitation requires a user to open an attacker-distributed packaged application; it exposes credentials and permits persistent changes such as overwriting shell startup files.

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.
