CVE-2026-7018Public exploitNetwork attack vector

Unauthenticated account impersonation via forged JWTs

Published Apr 26, 2026 · Updated Apr 26, 2026

Authentication bypass in Datavane Datavines through commit 13607645e14a4982468cfdbcf75c85cde63bae71 allows remote attackers to forge JWTs. TokenManager falls back to a shared secret, while AuthenticationInterceptor compares a token password with the same token-derived value. Under the default configuration, knowledge of a valid username is sufficient to impersonate that user and access protected API endpoints without a password.
