CVE-2026-42018 is an improper authentication vulnerability in JFrog Artifactory.
The flaw is tracked as CWE-287.
It affects the anonymous-user token handling path.
When anonymous access is disabled, unauthenticated callers should be denied.
Instead, Artifactory could return an internal anonymous-user token.
The token is meant for internal anonymous-user processing.
Returning it to an unauthenticated caller breaks authentication.
An attacker does not need valid credentials.
Network access to the Artifactory service is enough.
The exposed token may grant access to resources trusting anonymous identity.
This can expose sensitive repositories, metadata, or artifacts.
JFrog is the CVE source.
NVD published the CVE on Aug 12, 2026.
NVD last modified it on Sep 12, 2026.
