Attackers Chain JFrog Artifactory Flaws to Gain Admin Control and Plant Backdoors
Attackers chained JFrog Artifactory flaws CVE-2026-42018 and CVE-2026-42016 for admin control, planting Rust backdoors; CVE-2026-82329 also mass-exploited.
Wiz observed attackers chaining CVE-2026-42018 (anonymous-token leak) and CVE-2026-42016 (token escalation) in self-hosted JFrog Artifactory between August 15 and September 8, gaining admin control, creating admin accounts, and installing malicious Groovy plugins and a custom Rust backdoor. Separately, critical authentication bypass CVE-2026-82329 (CVSS 9.8) was mass-exploited starting September 1, drawing ~406,000 exploitation attempts on September 2 per Fastly. CISA added CVE-2026-82329 to KEV on September 2 with a September 5 federal deadline. Patching does not revoke minted tokens or rotate stolen join keys; admins must review accounts and rotate credentials.

CISA Added JFrog Artifactory Vulnerability to its Known Exploited Vulnerabilities Catalog (CVE-2026-82329)
CISA added the actively exploited JFrog Artifactory flaw CVE-2026-82329 (CVSS 9.8) to its KEV catalog; unauthenticated attackers gain admin access.
CISA added CVE-2026-82329, a critical improper authentication flaw in JFrog Artifactory, to its Known Exploited Vulnerabilities Catalog with a September 5, 2026 patch deadline. The CVSS v3.1 9.8 flaw allows unauthenticated attackers with network access to obtain administrative privileges under the default configuration. WatchTowr honeypot data shows attackers minting administrator tokens, enumerating users, groups, and federated access topologies, and in some cases creating backdoor users for persistence. Users must upgrade to Artifactory 7.161.20 or the applicable fixed release; Qualys detects vulnerable assets via QID 735249.

Attackers Exploit Critical JFrog Artifactory Flaw to Mint Admin Tokens Days After Disclosure
Threat actors exploit CVE-2026-82329, a default-config authentication bypass in JFrog Artifactory, to mint administrator tokens days after patch release.
watchTowr reports that CVE-2026-82329 (CVSS 9.8), an authentication bypass in JFrog Artifactory patched in version 7.161.20 on August 28, 2026, is being actively exploited as of September 1. The flaw, in JFrog Access, lets unauthenticated attackers abuse a 'phantom' join key on default configurations to forge access and mint administrator-level credentials. Observed activity includes admin token generation, user, group, and token enumeration, and backdoor user creation in limited cases, raising supply chain poisoning and lateral movement risks for the widely used artifact repository.

U.S. CISA adds GitLab, JFrog Artifactory, and ConnectWise ScreenConnect flaws to its Known Exploited Vulnerabilities catalog
CISA added four actively exploited GitLab, JFrog Artifactory, and ConnectWise ScreenConnect flaws to the KEV catalog with imminent deadlines.
CISA added CVE-2026-42016 and CVE-2026-42018 (JFrog Artifactory), CVE-2026-84869 (ConnectWise ScreenConnect), and CVE-2026-85706 (GitLab, CVSS 10.0) to its KEV catalog. Artifactory flaws are being chained with CVE-2026-82329 in attacks observed August 15 to September 8, taking over self-hosted servers, creating persistent administrator accounts, and installing backdoors. ScreenConnect CVE-2026-84869 allows unauthorized file transfer and execution during remote sessions, linked by Huntress to malicious VBScript deliveries, and is fixed in version 26.6.5. GitLab's repository commits API path traversal exposes SSH keys, database credentials, deploy tokens, and CI/CD variables, with watchTowr already observing in-the-wild probes. Federal agencies must patch GitLab and ScreenConnect flaws by September 14, 2026, and Artifactory flaws by September 25, 2026.

Another Artifactory CVE under attack by AI agents or humans
Attackers are actively exploiting CVE-2026-82329, a critical JFrog Artifactory authentication bypass, minting admin tokens on exposed servers days after patch release.
CVE-2026-82329 is a CVSS 9.8 unauthenticated authentication bypass in JFrog Artifactory, disclosed Friday, that allows attackers to create new administrative credentials. watchTowr's honeypots recorded exploitation from a small number of IPs within days, including enumeration of users, groups, credential sets, and federated access topologies. Researchers urge urgent patching, credential rotation, and treating exposed instances as potentially compromised to prevent build-pipeline tampering and downstream supply-chain impact.

Root RCE Zero-Day in Cisco Secure Email Gateway Under Active Exploitation
Cisco warns CVE-2026-76461 (CVSS 9.8), an unauthenticated root RCE in Secure Email Gateway AsyncOS, is actively exploited in the wild.
Cisco confirmed that CVE-2026-76461, a CVSS 9.8 email-parsing flaw in Secure Email Gateway AsyncOS, is being exploited in the wild since September 2026, allowing unauthenticated remote attackers to execute arbitrary commands with root privileges via crafted emails containing malicious SQL statements. All physical and virtual SEG configurations are affected; Secure Email and Web Manager and Secure Web Appliance are not. CISA added the flaw to the KEV catalog with a September 17 federal remediation deadline, and Cisco released IoCs while noting root access lets attackers remove them.

CISA Adds Seven Exploited Flaws as Attackers Deploy Reverse Shells and Crypto Miners
CISA added seven actively exploited vulnerabilities to its KEV catalog, including SonicWall SMA 1000 SSRF CVE-2026-83548, amid campaigns deploying reverse shells and crypto miners.
CISA's KEV additions cover flaws in SonicWall SMA 1000 (CVE-2026-83548, CVE-2026-83549), Sangoma Switchvox (CVE-2026-9586), JFrog Artifactory (CVE-2026-82329), Kludex Starlette (CVE-2026-48710), Kestra OSS (CVE-2026-49869) and Berri LiteLLM's MCP endpoint (CVE-2026-59822). SonicWall confirmed active exploitation of the SMA 1000 flaws, while Microsoft and Wiz reported attackers chaining LiteLLM flaws CVE-2026-42271 and CVE-2026-48710 to fingerprint hosts, steal provider API keys and deploy XMRig miners on AI infrastructure. Wiz linked exploitation of the LiteLLM chain to the Qilin ransomware group, and Microsoft detailed a Kestra compromise chain ending in cryptocurrency mining and data harvesting via exposed RAGFlow flaws.
