CVE-2026-1639Network attack vector

Database disclosure via unescaped project-list sorting parameters

Published Feb 18, 2026 · Updated Feb 18, 2026

Time-based blind SQL injection in Taskbuilder 5.0.2 and earlier allows remote authenticated users to read WordPress database data. The project-list query interpolates user-controlled order and sort_by values without sufficient escaping or prepared-query binding. Subscriber-level access is sufficient to append SQL expressions; the reported consequence is sensitive database disclosure, not data modification.
