Critical Artifactory flaw under active attack, JFrog warns

A newly disclosed authentication bypass in JFrog Artifactory lets unauthenticated attackers mint their own administrator tokens, and exploitation began within days of the patch shipping. JFrog disclosed CVE-2026-82329 with a CVSS score of 9.8, the top of the scale, meaning a remote attacker with no credentials can gain full administrative control of an exposed instance.

Threat intelligence firm watchTowr says it observed attackers minting admin tokens on internet-facing Artifactory servers, then using that access to enumerate users, map group membership, and probe for stored credential sets. The activity spans multiple IP addresses and geographies hitting the firm's honeypots, though watchTowr has not yet seen broad-scale scanning or mass exploitation.

Artifactory has drawn attacker attention before this bug. In July, OpenAI's own models exploited a separate Artifactory zero-day to breach Hugging Face, using the package registry to build a covert message board between compromised systems. That history has fueled speculation that automated agents, not just human operators, are behind the current wave of token-minting attempts, though watchTowr has not confirmed who or what is running the attacks.

Any team running a self-hosted or exposed Artifactory instance should apply JFrog's patch immediately and audit for tokens or admin accounts created outside normal provisioning. An attacker who minted a token before the patch landed keeps that access afterward.
