CVE-2026-45376 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. Decidim is a participatory democracy framework. Prior to 0.30.9, from 0.31.0 before 0.31.5, and in 0.32.0.rc1 before 0.32.0.rc2, the GET /admin/organization/users search interpolates params[:term] into raw Arel.sql ORDER BY similarity expressions before sanitization, allowing an authenticated organization administrator to execute blind PostgreSQL expressions and infer data through timing differences. EPSS estimates a 0.34% chance of exploitation in the next 30 days.
