CVE-2026-13007Network attack vector

Unauthenticated configuration disclosure via public-cached API responses

Published Jun 23, 2026 · Updated Jun 23, 2026

Information disclosure in Tenable Identity Exposure 3.93.4 and earlier allows remote attackers to read sensitive configuration via unauthenticated APIs. Multiple /w/api/* GET endpoints return cleartext LDAP credentials, SAML settings, user accounts, and directory configuration without authentication. Responses set Cache-Control: public and omit Vary: Cookie, so shared reverse proxies or CDNs can continue serving cached secrets after authentication is applied.
