Artifactory flaws chained in attacks deploying backdoor malware

Threat actors are exploiting critical and high-severity vulnerabilities in JFrog Artifactory to bypass authentication, gain administrative privileges, and deploy a Rust backdoor on vulnerable self-hosted servers.
A new report from cloud security company Wiz confirmed exploitation across multiple environments, including an exploit chain that combines CVE-2026-42018 and CVE-2026-42016.
The third vulnerability is CVE-2026-82329, a critical authentication bypass that offensive security company watchTowr observed being exploited earlier this month to mint administrator tokens.
According to Wiz, attackers exploit CVE-2026-42018 to obtain a JSON Web Token (JWT) belonging to an internal Artifactory anonymous user, even when anonymous access is disabled, with low privileges.
Then they increase permissions to admin level by exploiting CVE-2026-42016, caused by insufficient token validation.
Between August 15 and September 8, multiple threat actors exploited the two vulnerabilities to obtain a JWT for the internal anonymous user and then exchange it for an admin-scoped token.
The researchers note that in some cases the attacker took less than five minutes to create an administrator account.
After creating admin accounts and generating long-lived access tokens, the attackers installed malicious Groovy plugins to execute arbitrary commands and established persistence by deploying a Rust-based backdoor.
“Between August 15 and September 8, 2026, we observed multiple actors chain CVE-2026-42018 and CVE-2026-42016 against self-hosted Artifactory instances,” Wiz says.
“Across multiple cases, we observed a custom Rust backdoor with C2 capabilities being dropped.”
In the next stage, the threat actor downloaded additional payloads into /dev/shm, /tmp, and /var/tmp, uploaded webshells, stole Artifactory configuration data and cluster join keys, enumerated repositories, tokens, and users, and added their SSH keys to newly created accounts.
Wiz warns that between 49% and 62% of reachable Artifactory instances are vulnerable to at least one of the three flaws.
System administrators are recommended to upgrade immediately to one of the following Artifactory release versions or later:
7.111.21
7.117.28
7.125.20
7.133.29
7.146.38
7.161.20
After upgrading, investigate internet-exposed instances for unexpected token creation, rogue administrator accounts, suspicious plugin activity, and enumeration requests, and restrict access to trusted systems only.
Wiz has listed indicators of compromise (IoCs) associated with the observed attacks to help defenders detect them quickly.
BleepingComputer has contacted JFrog to confirm the reported activity, but we have not received a response as of publication.

Threat actors have demonstrated the ability to chain critical and high-severity vulnerabilities within JFrog Artifactory to achieve privilege escalation and deploy sophisticated backdoor malware on vulnerable self-hosted servers. This exploitation was confirmed by cloud security company Wiz, which identified this exploit chain involving CVE-2026-42018, CVE-2026-42016, and CVE-2026-82329. The attack sequence involved exploiting CVE-2026-42018 to illicitly obtain a JSON Web Token belonging to an internal Artifactory anonymous user, even when anonymous access was supposedly disabled and the user possessed low privileges. Subsequently, the threat actors leveraged CVE-2026-42016, which stems from insufficient token validation, to elevate these initial privileges to administrator level. Between August 15 and September 8, 2026, multiple threat actors successfully utilized this two-step process to generate administrator-scoped tokens.

Following the privilege escalation, the attackers proceeded to install malicious Groovy plugins, which allowed them to execute arbitrary commands on the affected systems, establishing persistence by deploying a Rust-based backdoor configured with Command and Control capabilities. The post-exploitation phase involved extensive reconnaissance and data exfiltration, where threat actors downloaded additional payloads into temporary directories such as /dev/shm, /tmp, and /var/tmp. They subsequently uploaded webshells and stole sensitive Artifactory configuration data, including cluster join keys, repository details, user lists, and access tokens. Furthermore, they modified the system by adding their SSH keys to newly created administrator accounts. Wiz reported that between forty-nine and sixty-two percent of reachable Artifactory instances were susceptible to at least one of these three flaws.

To mitigate this severe risk, system administrators are strongly advised to immediately upgrade their Artifactory instances to one of the recommended release versions or later, including 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38, or 7.161.20. After implementing the necessary upgrades, defenders must conduct thorough investigations on internet-exposed instances to detect anomalous activity, such as unexpected token creation, the appearance of rogue administrator accounts, suspicious plugin execution, and excessive enumeration requests. Access should then be strictly limited to trusted systems. The findings are attributed to work by Bill Toulas.
