When AI infrastructure becomes the target: Securing gateways and control points
Microsoft Threat Intelligence details attacks on exposed AI workloads exploiting LiteLLM gateways for credential harvesting, persistence, and cryptomining.
Microsoft Threat Intelligence examines attacks targeting exposed AI workloads, including exploitation of LiteLLM gateway deployments. Post-exploitation activity includes credential harvesting, establishing persistence, and cryptomining. The post urges defenders to secure AI infrastructure gateways and control points; the available text does not name threat actors, CVEs, or provide IOCs.
Acronis Plugin Vulnerability in cPanel and Plesk Exploited in the Wild
Acronis patched CVE-2026-87886 (CVSS 7.8), a local privilege escalation flaw in its cPanel and Plesk backup plugins, exploited in targeted attacks.
Acronis released fixes for CVE-2026-87886 (CVSS 7.8, CWE-276), an insecure file permissions flaw in Linux-based backup components for cPanel & WHM and Plesk that enables local privilege escalation. The vendor observed limited, targeted exploitation in the wild before patches shipped. Fixes are available in Backup plugin for cPanel & WHM 1.9.3 HF3 and Backup extension for Plesk 1.8.11. A local attacker with low privileges could gain elevated access to backup data, control panels, and other customer accounts on shared hosting infrastructure.
Hackers Exploit Marimo RCE to Steal AWS Credentials and Reach Bastion Host in 8 Seconds
Attackers exploited pre-auth RCE CVE-2026-39987 in Marimo notebooks to steal AWS credentials and SSH into a bastion host in eight seconds.
Sysdig Threat Research Team documented an intrusion abusing CVE-2026-39987, an unauthenticated RCE in Marimo's terminal WebSocket endpoint affecting versions up to 0.20.4 and fixed in 0.23.0. The attacker harvested AWS credentials from the host environment and Redis backend, queried AWS Secrets Manager to retrieve an SSH private key, and authenticated to an internet-facing SSH bastion host just eight seconds after opening the WebSocket session. Human-operated custom tooling, not an AI agent, executed the full exploit-to-lateral-movement chain.
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.
CISA Flags Actively Exploited Ray Flaw That Can Trigger Browser
CISA added actively exploited Ray flaw CVE-2025-62593 (CVSS 9.4) to its KEV catalog; the DNS rebinding RCE has powered crypto-mining and DDoS botnet campaigns.
CISA added CVE-2025-62593 (CVSS 9.4) to its Known Exploited Vulnerabilities catalog, citing active exploitation of a DNS rebinding-driven RCE flaw in the Ray distributed computing framework, fixed in version 2.52.0. The flaw stems from missing authentication on critical Ray endpoints and an insufficient User-Agent header guard, exploitable against developers running Ray in Firefox or Safari via malicious websites or ads. RondoDox botnet operators incorporated the PoC exploit before the November 26, 2025 disclosure, and unpatched GPU-equipped clusters were hijacked into self-replicating crypto-mining botnets in the ShadowRay 2.0 campaign. FCEB agencies must apply fixes by August 20, 2026.

Week in review: Linux rootkit deployed on F5 BIG-IP APM devices, Cisco FMC bugs exploited
Weekly roundup: Cisco FMC and N-able N-central zero-days exploited in the wild, MikroTik RouterOS hijacks, Microsoft Patch Tuesday ships two exploited zero-days.
State-sponsored and financially-motivated attackers are actively exploiting CVE-2026-20079, a critical authentication bypass in Cisco Secure Firewall Management Center (FMC), alongside CVE-2026-20316. N-able issued an emergency hotfix for CVE-2026-86218, a critical pre-auth RCE in the N-central RMM platform exploited in the wild. CERT Polska disclosed six RouterOS vulnerabilities being chained to hijack internet-exposed MikroTik devices. Microsoft's September 2026 Patch Tuesday shipped a record patch count including two zero-days, while roughly 67,000 Trezor customers faced phishing after a shipping-partner breach and researchers privately disclosed a zero-click WeChat worm to Tencent.
Off Guard: Breaking LiteLLM from authentication bypass to cloud compromise
Wiz found LiteLLM auth bypass (CVE-2026-59822) and post-auth RCE (CVE-2026-59821) chainable to cloud compromise; the bypass is in CISA KEV with in-the-wild exploitation.
Wiz scanned roughly 3,074 internet-facing LiteLLM deployments and found 9.6% accepted the default master key sk-1234 or required no authentication, making post-auth attacks effectively pre-auth. The MCP endpoint accepts any Bearer token and grants a valid session (CVE-2026-59822), confirmed exploited in the wild via honeypots and added to CISA's Known Exploited Vulnerabilities catalog. Custom code guardrails allow post-auth root-level RCE via exec(compile(...)) (CVE-2026-59821), while pass-through endpoints lack URL validation, enabling cloud credential theft in post-auth scenarios. All assigned vulnerabilities have been patched; the research was presented at DEF CON 34.
