Severity: medium · Patch status: unknown · Since 2026-08-27 · CVE-2026-66384
JFrog Artifactory contains an improper limitation of a pathname to a restricted directory vulnerability. This can allow an authenticated user to write data outside the intended Docker cache path under specific remote-repository conditions. CISA added CVE-2026-66384 to its Known Exploited Vulnerabilities catalog on Aug 27, 2026, which means attackers are exploiting it in the wild.
What to do
- Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
- US federal agencies must remediate by Sep 10, 2026 (BOD 22-01); treat that as the outer limit.
