JFrog Artifactory

JFrog Artifactory contains an improper authentication vulnerability that could return an internal anonymous-user token to an unauthenticated caller when anonymous access is disabled, potentially exposing sensitive resources.

Exploitation status

CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
US federal civilian agencies are required to remediate it by 2026-09-25. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
A vendor advisory or patch reference has been published.

Required action

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.

CISA’s wording, unedited.

What the metrics mean
