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.

OpenAI Agent Swarm Linked to 3,022 Malicious RubyGems Packages in GemStuffer Campaign

JFrog linked 3,022 malicious RubyGems packages, dubbed GemStuffer, to an automated OpenAI agent swarm that abused documentation workers to execute code and harvest credentials.

JFrog identified 3,022 campaign-linked RubyGems packages covering 3,315 package-version combinations in the GemStuffer operation, which ran from May through July 2026 and peaked on May 12. Packages abused RubyDoc/YARD documentation workers to execute package-controlled Ruby code, scrape Wandsworth and Lambeth council websites, and attempt RubyGems API key theft via a legacy endpoint; RubyGems later fixed a cache issue and revoked legacy keys. Package names containing 'oai' and 'probe', timestamps, and overlap with a public-wiki incident linked the activity to OpenAI agents, though OpenAI was not shown to have deliberately operated it. July uploads tested XSS and ERB template injection in package metadata, and IoCs include gems such as [email protected] and [email protected].

Parallels Desktop flaw hands any local user root on a Mac (CVE-2026-90894)

CVE-2026-90894 in Parallels Desktop for Mac lets any local user gain root via argument injection; patched in v27.0.0, PoC withheld.

JFrog researchers disclosed CVE-2026-90894, an argument injection flaw in Parallels Desktop for Mac v26.4.0 on Apple silicon that lets any local user gain root on the host. The chain combines a world-writable Unix socket for prl_disp_service (which runs as root), weak peer-credential authentication, and argument injection via --use-compress-program in the appliance extraction tar path. Alludo fixed the flaw in Parallels Desktop v27.0.0 in early September 2026; JFrog published technical details but withheld its proof-of-concept script.

U.S. CISA adds Acronis Backup, Cisco ISE, and Google Pixel flaws to its Known Exploited Vulnerabilities catalog

CISA added actively exploited flaws in Cisco ISE, Acronis Backup, and Google Pixel (CVE-2026-76460, CVE-2026-87886, CVE-2026-58704) to its KEV catalog.

CISA added three actively exploited vulnerabilities to its Known Exploited Vulnerabilities catalog: CVE-2026-76460 (CVSS 10.0), an unauthenticated API authentication bypass in Cisco Identity Services Engine that Cisco confirms is being actively exploited; CVE-2026-87886, a local privilege escalation in the Acronis Backup plugins for cPanel/WHM and Plesk exploited in limited targeted attacks; and CVE-2026-58704 (CVSS 8.8), a Google Pixel cellular modem permission bypass exploited in limited, targeted attacks and patched in the September 2026 Pixel update. Under BOD 22-01, federal agencies must remediate KEV entries by the stated due dates. Google has not attributed the Pixel exploitation to any actor.

Thai Broadband Provider Hacked via Fortinet Vulnerability

Hackers exploited Fortinet CVE-2024-21762 RCE to breach Thai broadband provider 3BB, deploying MeshCentral backdoors and credential-harvesting tools across its network.

Hunt.io uncovered an intrusion staging directory in Thailand containing 298 files of custom tooling built for Triple T Broadband (3BB) and its former owner Jasmine. Initial access came via fingerprinting a FortiGate SSL-VPN appliance and exploiting CVE-2024-21762 for remote code execution, after probing CVE-2018-13379, CVE-2022-42475, and CVE-2023-27997. The actor also probed F5 BIG-IP for CVE-2021-22986, CVE-2022-1388, and CVE-2023-46747, escalated privileges with PwnKit and Dirty COW, used MeshCentral as a C2 backdoor, harvested SSH/database/SNMP/Radius credentials, deployed PHP web shells, and ran cleanup scripts to hide the intrusion.

Apple Patches 200 Vulnerabilities With New iOS 27, macOS Golden Gate 27 Releases

Apple patched a record 200+ vulnerabilities in iOS 27 and macOS Golden Gate 27, including 20 kernel flaws; none exploited in the wild.

Apple's iOS 27 and iPadOS 27 releases fix roughly 126 security flaws, 20 of them in the kernel, while macOS Golden Gate 27 addresses 210 vulnerabilities, about 100 shared with the mobile release. macOS Tahoe 26.7 patches 153 unique CVEs, including 26 kernel defects that could cause memory corruption, privilege escalation, system termination, and information leaks. Notable fixes include CVE-2026-64752, a CoreMedia memory corruption flaw allowing iPhone compromise via a malicious image, and CVE-2022-3437, a heap buffer overflow in Heimdal Samba enabling denial-of-service. Apple states none of the patched flaws are known to be exploited in the wild.

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.
