CVE-2023-40788Public exploitNetwork attack vector

Unauthenticated error-log disclosure via gateway skip list

Published Sep 18, 2023 · Updated Sep 25, 2024

Incorrect access control in the SpringBlade gateway through 3.6.0 allows remote attackers to read application error logs without authentication. AuthProvider places /log/** and /error/** in DEFAULT_SKIP_URL, so the gateway bypasses token checks for every request matching those paths. The default skip-list configuration is sufficient for access, and exposure is limited to information recorded in the error logs.
