CVE-2026-82329: JFrog Artifactory improper authentication allows admin takeover

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 17 September 2026. Confidence: medium.

critical priorityUnauthenticated network-reachable flaw yielding administrative privileges, rated CVSS 9.8 and listed in CISA KEV as exploited.

What it is

JFrog Artifactory contains an improper authentication weakness (CWE-287) that, under default configuration, may let an unauthenticated attacker with network access obtain administrative privileges. Because the flaw is reachable without credentials and grants full admin rights, it is a severe risk to any exposed instance. The record does not specify which versions are affected.

Impact

An attacker gains administrative control of the Artifactory instance, which can expose stored artifacts, credentials and build pipeline data and allow tampering with the software supply chain. The CVSS vector rates confidentiality, integrity and availability impact as high.

Attack surface

Reached over the network (AV:N) with no authentication (PR:N) and no user interaction (UI:N), so any internet- or network-exposed Artifactory endpoint is a candidate target. The description ties the weakness to default configuration, meaning unhardened deployments are the primary exposure.

Exploitation

CISA added this CVE to the Known Exploited Vulnerabilities catalog on 2026-09-02, indicating known exploitation in the wild. EPSS gives a 30-day probability of 0.07666 (94.3rd percentile), and no ransomware campaign use is documented.

What to do

• Apply the vendor fix from the JFrog security advisories and release notes; CISA's KEV due date was 2026-09-05, so treat patching as urgent.
• If no patch is available for your version, follow CISA BOD 26-04 guidance for cloud services or discontinue use of the product.
• Remove Artifactory from direct internet exposure and restrict network access to trusted management networks until patched.
• Review and harden default authentication configuration, and rotate administrative credentials and tokens after remediation.
• Audit for unauthorized admin accounts, configuration changes and anomalous artifact activity.

Detection

• Hunt for authentication events that result in admin-level access from unauthenticated or unexpected source IPs.
• Alert on creation of new administrative users, API keys or tokens outside change windows.
• Monitor for configuration changes to authentication and security settings in Artifactory logs.
• Correlate network access to Artifactory endpoints from external or untrusted ranges with subsequent privileged actions.
