Another Apache Log4j Vulnerability Is Actively Exploited in the Wild (CVE-2021
Apache Log4j 2 RCE CVE-2021-44228 is actively exploited via crafted JNDI lookups; Palo Alto Unit 42 urges upgrading to Log4j 2.17.1.
Unit 42 details CVE-2021-44228, an easily exploited remote code execution flaw in Apache Log4j 2 where attacker-supplied JNDI lookups in logged user input cause payload download and execution. Massive internet-wide scanning for unpatched systems has begun, with observed follow-on activity including information stealing, Cobalt Strike delivery, and coinmining. The recommended fix is Log4j 2.17.1, which also patches CVE-2021-45046, CVE-2021-45105, and CVE-2021-44832. Widely used Java software including Apache Struts, Solr, Druid, Flink, ElasticSearch, and Spring Boot is affected.

JFrog Artifactory Vulnerabilities Actively Exploited in the Wild to Gain Administrative Control
Wiz observed active exploitation of three JFrog Artifactory flaws used to mint admin tokens, deploy malicious plugins, and install Rust backdoors on self-hosted servers.
JFrog Artifactory flaws CVE-2026-42016, CVE-2026-42018, and CVE-2026-82329 are being actively exploited against self-hosted instances, enabling token exposure, token scope abuse, and a critical default-configuration authentication bypass. Wiz observed attackers chaining CVE-2026-42018 and CVE-2026-42016 from August 15 to September 8, 2026, creating persistent administrator accounts in under five minutes, deploying malicious Groovy plugins, and installing Rust-based backdoors. At disclosure, 67-69 percent of Wiz-monitored organizations ran vulnerable instances; fixed releases include 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38, and 7.161.20 or later depending on branch.

Hackers Exploit JFrog Artifactory Flaws to Bypass Authentication and Gain Admin Access
Wiz Research observes multiple attackers exploiting three JFrog Artifactory flaws, including default-configuration authentication bypass CVE-2026-82329, to gain admin access and deploy backdoors.
Attackers chain CVE-2026-42018 and CVE-2026-42016 to exchange anonymous JWTs for administrator-scoped tokens, or exploit CVE-2026-82329 directly via the registry join endpoint to obtain admin privileges under default configuration. Post-exploitation observed by Wiz includes persistent admin users created within five minutes, malicious Groovy plugins for command execution, and Rust-based backdoors dropped to /tmp, /var/tmp, and /dev/shm with C2 communications. Compromise exposes software artifacts, repository credentials, CI/CD integrations, and cluster secrets, creating supply chain risks. Fixed releases include 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38, and 7.161.20.

Artifactory Under Attack: In-the-Wild Exploitation of CVE-2026-42016, CVE-2026-42018 & CVE-2026-82329
Wiz Research confirms in-the-wild exploitation of three JFrog Artifactory vulnerabilities, chained to gain administrative control, deploy Groovy plugins, and install Rust backdoors.
Wiz Research identified active exploitation of CVE-2026-42016, CVE-2026-42018, and CVE-2026-82329 in JFrog Artifactory between August 15 and September 8, 2026. Attackers chain the anonymous-token exposure (CVE-2026-42018) with the token scope-validation flaw (CVE-2026-42016) to obtain admin-scoped tokens, while CVE-2026-82329 allows unauthenticated administrative access in default configurations. Observed post-exploitation includes persistent administrator accounts created in under five minutes, malicious Groovy plugin deployment, ad-hoc command execution, Rust-based C2 backdoors dropped to writable paths, and webshell uploads. Wiz measured that 59-62% of organizations running Artifactory remained vulnerable to the chained CVEs weeks after disclosure, and the vulnerabilities were already included in CISA KEV.
