Artifactory flaws chained in attacks deploying backdoor malware

Attackers chain JFrog Artifactory flaws CVE-2026-42018 and CVE-2026-42016 to gain admin tokens and deploy a Rust backdoor on self-hosted servers.

Wiz observed multiple threat actors chaining CVE-2026-42018 and CVE-2026-42016 against self-hosted JFrog Artifactory instances between August 15 and September 8, 2026, in some cases obtaining admin access in under five minutes. The critical authentication bypass CVE-2026-82329 was also exploited this month to mint administrator tokens. Attackers installed malicious Groovy plugins, dropped a Rust backdoor with C2 capabilities, uploaded webshells, stole configuration data and cluster join keys, and added SSH keys to new accounts. Wiz estimates 49-62% of internet-reachable Artifactory instances are vulnerable to at least one of the three flaws, and patched releases from 7.111.21 through 7.161.20 are available.

Magento StyleSmuggler zero-day exploited to deploy Linux backdoor

StyleSmuggler zero-day in Magento and Adobe Commerce is actively exploited in the wild to deploy a Rust-based Linux backdoor; fix not yet released.

A zero-day dubbed StyleSmuggler affecting all versions of Magento and Adobe Commerce is being actively exploited, with the first observed incident on September 4 on a fully patched site. The exploit injects PHP code via Magento's template system through a fake 'failed-payment' email to achieve code execution, installing a Rust-based backdoor disguised as kworker/u:8:0 or fc-cache with a 30-minute cron job for persistence. The backdoor communicates via TLS/WebSockets or UDP port 123 masquerading as NTP traffic, checks TracerPid to detect tracing, and can receive remote commands. Adobe confirmed it is working on a fix with no timeline; Sansec recommends disabling GraphQL as mitigation and monitoring for suspicious cron entries and kworker or fc-cache processes. Magento is installed on more than 160,000 websites, including 14,000 of the top 1 million sites.

Rust Supply Chain Attack on arrayref: Significant Overlap with DPRK Campaigns

Malicious versions of the Rust crate arrayref executed a compile-time backdoor, with infrastructure overlapping recent DPRK supply chain attacks on Mastra and axios.

Wiz researchers report that malicious versions of the arrayref Rust crate ran a backdoor during compilation, compromising developer build pipelines. The campaign's command-and-control infrastructure significantly overlaps with infrastructure used in recent DPRK supply chain attacks, including campaigns against Mastra and axios. Developers using affected crate versions should audit their builds and review dependencies.
