CVE-2026-7306Public exploitNetwork attack vector

Unauthenticated management calls via default access token

Published Apr 28, 2026 · Updated Apr 28, 2026

Authentication bypass in xuxueli XXL-JOB 3.3.0 through 3.3.2 allows remote attackers to invoke privileged OpenAPI operations. OpenApiController disables SSO for /api/{uri} and compares only the request header against the publicly shipped default_token value. Exposure requires a reachable admin endpoint left with that default; attackers can register or remove executors and forge callbacks.
