LiteLLM Flaws Let Attackers Execute Code as Root and Steal Cloud Credentials
Wiz disclosed LiteLLM flaws including CVE-2026-59822 MCP auth bypass, now in CISA KEV, enabling root RCE and AWS credential theft from exposed gateways.
Wiz researchers disclosed weaknesses in the open-source LiteLLM AI gateway: CVE-2026-59821 allows authenticated administrators to execute code as root via the Custom Code Guardrails feature, while CVE-2026-59822 is an MCP authentication bypass where a meaningless Bearer token establishes a valid session. The MCP bypass was observed in the wild through Wiz honeypots and added to CISA's Known Exploited Vulnerabilities catalog on September 2. A scan of 3,074 internet-facing instances found 294 (9.6%) accepting the default master key sk-1234 or lacking authentication. Fixes shipped in LiteLLM 1.82.0 (guardrail hardening) and 1.84.0 (MCP bypass); exposed instances can leak provider API keys and temporary AWS IAM credentials via the pass-through feature and metadata service, with a related config-check issue tracked as CVE-2026-35029.

Enterprises Warned of Attacks Exploiting WSO2 Vulnerability
Attackers are actively exploiting CVE-2026-5430 (CVSS 10), a WSO2 JWT authentication bypass, to access enterprise API credentials and sensitive data.
WatchTowr's honeypot network recorded the first exploitation attempt of CVE-2026-5430 on September 13, roughly two months after the CVE record was published in early August. The flaw, patched by WSO2 in April with an advisory in May, carries a maximum CVSS score of 10 and allows JWT authentication bypass via tokens signed with unsupported algorithms, enabling unauthorized access and full account takeover. A forged JWT observed in the wild granted access to API backend endpoints, credentials, and consumer keys and secrets for every registered application. WSO2's API Manager, API Control Plane, Traffic Manager, and Universal Gateway are affected, and the platform serves nearly 1,000 enterprise customers in banking, government, telecom, and logistics.

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.

CISA Warns of Citrix NetScaler Authentication Bypass Vulnerability Exploited in Attacks
CISA adds exploited Citrix NetScaler authentication bypass CVE-2026-19490 to the KEV catalog; federal agencies must patch by September 12.
CISA added CVE-2026-19490, a CWE-288 authentication bypass affecting NetScaler ADC and Gateway deployments configured as AAA virtual servers or Gateway services (including SSL VPN, ICA Proxy, and RDP Proxy), to the Known Exploited Vulnerabilities catalog. Citrix released fixes on August 19, 2026; honeypots recorded 56 attack attempts between September 3 and 8 after a public PoC, though no confirmed production compromises have been reported. Affected builds include 14.1 before 14.1-73.32 and 13.1 before 13.1-63.21; newer installations require SAML IdP configuration to be exposed.

CISA Adds Two Known Exploited Vulnerabilities to Catalog
CISA added actively exploited CVE-2026-76460 (Cisco Identity Services Engine) and CVE-2026-87886 (Acronis Backup) to its KEV catalog.
CISA added two vulnerabilities to its Known Exploited Vulnerabilities Catalog based on evidence of active exploitation: CVE-2026-76460, an incorrect use of privileged APIs flaw in Cisco Identity Services Engine, and CVE-2026-87886, an incorrect default permissions flaw in Acronis Backup. Under Binding Operational Directive 26-04, Federal Civilian Executive Branch agencies must prioritize rapid remediation of KEV vulnerabilities on publicly exposed assets that grant total control post-exploitation, and check whether systems were compromised before patching.

Weekly Cybersecurity Newsletter Bulletin – Microsoft 0-day, FortiOS, PAN-OS Flaw, Revolut Data Breach, and 20+ Stories
Weekly roundup: Microsoft patches 973 flaws including two actively exploited zero-days; FortiOS CAPWAP flaw deploys PivotC2 RAT; PAN-OS root RCE disclosed.
Microsoft's September 2026 Patch Tuesday fixed 973 vulnerabilities, including two zero-days under active exploitation: CVE-2026-85880 (Windows ALPC) and CVE-2026-81963 (Windows Update Stack), both elevation-of-privilege bugs. SOCRadar reported active exploitation of CVE-2025-25249 (CVSS 9.8) in FortiOS CAPWAP, deploying a Node.js RAT called PivotC2 that exfiltrates Exchange mailboxes to Wasabi cloud storage; 178 devices were compromised out of 30,000 scanned IPs, attributed to a Russian-speaking financially motivated group. Palo Alto disclosed CVE-2026-0310, a 9.2-rated buffer overflow enabling root code execution on PA-Series firewalls, and Fortinet disclosed CVE-2026-84393, a ZTNA certificate validation MITM flaw. Cyera also revealed CVE-2026-6471 ('PostGREShell'), a 12-year-old PostgreSQL logical-decoding flaw allowing code execution via REPLICATION-privileged accounts.

CISA Warns of Critical GitLab Vulnerability Exploited in Attacks
CISA added actively exploited GitLab path traversal flaw CVE-2026-85706 to its KEV catalog, warning unauthenticated attackers can read arbitrary files including secrets.
CISA added CVE-2026-85706, an unauthenticated path traversal vulnerability (CWE-35) in the repository commits API of GitLab Community and Enterprise Editions, to its Known Exploited Vulnerabilities catalog on September 11, 2026, with a remediation deadline of September 14, 2026. The flaw allows arbitrary file reads via improper path confinement, potentially exposing configuration files, access tokens, private keys, and CI/CD variables that enable further intrusion and supply chain compromise. CISA requires forensic triage under Binding Operational Directive 26-04 and urges defenders to review logs for traversal requests and rotate potentially exposed credentials after patching.
