CVE-2026-103396

bbs-go through 4.4.6 Incorrect Authorization via /api/admin/user/synccount

Published Sep 30, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
bbs-go through 4.4.6 contains a permission bypass vulnerability in the AdminMiddleware authorization logic where the read-only dashboard.user.view permission rule matches the /api/admin/user/synccount endpoint before the intended dashboard.user.update rule. Authenticated users with only view permissions can call the synccount endpoint to trigger expensive full-table user recounts and cache invalidations, causing denial of service through repeated concurrent database operations.
