Unspecified impact via unbounded user name
Published Jan 14, 2023 · Updated Apr 7, 2025
Improper length validation in Publify before 9.2.10 allows remote authenticated users to trigger unspecified impact via an oversized user name. The User model accepts an unbounded name value; the upstream patch adds a 2,048-character maximum because the backing text column permits extremely long input. Exploitation requires high-privilege authentication and user interaction, while public sources do not specify the resulting confidentiality, integrity, or availability behavior.
