CVE-2023-2980Public exploitNetwork attack vector

Authenticated resource manipulation via user creation handler

Published May 30, 2023 · Updated Jan 10, 2025

Resource injection in the user creation handler in Pydio Cells 4.2.0 allows remote authenticated users to manipulate resource identifiers. The handler accepts an attacker-controlled resource identifier during account creation, but published sources omit its validation and downstream use. A valid low-privilege session is required; public records do not specify which resources can be altered or the resulting operational effect.
