CVE-2026-15267Network attack vector

Authenticated database disclosure via unquoted project filter

Published Jul 28, 2026 · Updated Jul 28, 2026

SQL injection in Taskbuilder 5.0.9 and earlier allows remote authenticated users to read database data via wppm_proj_filter. The project-task view replaces an integer conversion with sanitize_text_field(), inserts the result as an unquoted operand using esc_sql(), and interpolates it into the prepare format string. Subscriber-level access is sufficient to alter the resulting query and extract sensitive database information.
