Request failure via unbounded string attributes
Published Jan 14, 2023 · Updated Apr 7, 2025
Improper input validation in Publify before 9.2.10 allows attackers to interrupt requests by submitting oversized strings. Multiple Active Record models accept string attributes without application-level length limits, leaving MySQL to reject values beyond column limits. Published assessments disagree on required privileges and user interaction; the bounded consequence is failure of the affected request.
