Authenticated information disclosure via settings export
Published Oct 14, 2026 · Updated Oct 14, 2026
Access control failure in SonicWall Network Security Manager allows remote authenticated users to read sensitive data via settings export. The supplied record identifies on-premises 4.3.1 and earlier, but retrieved vendor material does not disclose the failed authorization check or the exposed fields. An NSM account is required; the record identifies administrator escalation and interception of other users' communications as downstream risks without explaining those chains.
