CVE-2026-45330Public exploitNetwork attack vector

Cross-tenant ID access via unscoped record lookup

Published Jul 31, 2026 · Updated Jul 31, 2026

IDOR in Decidim before 0.30.9, 0.31.0 through 0.31.4, and 0.32.0.rc1 allows remote authenticated users to access cross-tenant ID requests. Identity-document verification controllers pass a request-supplied pending authorization ID to Authorization.find without first restricting the query to current_organization. A tenant administrator with the Identity documents workflow enabled can view another tenant's submitted ID and approve or reject that tenant's request.
