UniFi OS scores a perfect 10.0 RCE, ConnectWise Automate agents can't verify their own updates
Unauthenticated command injection on UniFi OS devices, a supply-chain plugin verification bypass in ConnectWise Automate (CVSS 8.8), a privilege escalation in LiteLLM, and RCE in three ManageEngine products.
Drop what you're doing if you run UniFi gear. CVE-2026-34910 is a perfect 10.0: unauthenticated command injection on any network-reachable UniFi OS device. Nobody's reported exploitation in the wild yet, but the attack requires zero credentials and zero user interaction, so that window won't stay open long. Four more high-severity bugs round out the day, including a ConnectWise Automate supply-chain risk that MSPs need to look at fast.
Today's CVEs
Sorted by urgencyCVE-2026-43493
MSRCA bug in the Linux kernel's pcrypt module (parallel crypto) mishandles MAY_BACKLOG requests, which could let a local attacker cause memory corruption or crash the system. The CVSS is 8.4, but exploitation requires local access and a fairly specific crypto workload configuration, so real-world risk is limited for most environments.
- Affected estate
- Azure Linux 3.0 users running kernel 6.6.139.1-1, especially those using disk encryption or IPsec workloads that exercise the pcrypt path
- How to check
- Run `uname -r` and confirm whether the kernel version is 6.6.139.1-1 or earlier.
- Included because
- high CVSS; kernel-level bug; common cloud platform
- Action
- Update the kernel package to the fixed version and reboot.
- Why it matters
- A local attacker could crash the kernel or potentially escalate privileges on systems using parallel crypto operations.

CVE-2026-2740
NVDAn authenticated user on a ManageEngine agent machine can get remote code execution through a vulnerable third-party dependency in ADSelfService Plus, DataSecurity Plus, or RecoveryManager Plus. The attacker needs valid credentials, but once authenticated, they can run arbitrary code on the agent. CVSS 8.4, no known exploitation yet.
- Affected estate
- Anyone running ManageEngine ADSelfService Plus before build 6525, DataSecurity Plus before build 6264, or RecoveryManager Plus before build 6313
- How to check
- Log into each ManageEngine console and check the build number under Settings > Product Info. Also inventory agent versions on endpoints.
- Included because
- authenticated RCE; agents deployed broadly; common enterprise product
- Action
- Upgrade each product to the fixed build from ManageEngine's download center and push updated agents.
- Why it matters
- Any authenticated user can execute arbitrary code on agent machines, which are typically deployed across your entire fleet.

CVE-2026-47102
NVDLiteLLM before 1.83.10 lets any authenticated user promote themselves to proxy_admin by calling the /user/update endpoint with a modified user_role field. Once promoted, they have full admin access to every user, API key, model config, and prompt history in the platform. Users with the org_admin role can do this without any extra exploit chain.
- Affected estate
- Teams running LiteLLM proxy before version 1.83.10, especially multi-tenant or org-scoped deployments
- How to check
- Check your LiteLLM version with `litellm --version` or inspect your container image tag. Review the user table for unexpected proxy_admin entries.
- Included because
- trivial privilege escalation; no special conditions; exposes sensitive data and keys
- Action
- Upgrade to LiteLLM 1.83.10+ and audit all user roles for signs of privilege escalation.
- Why it matters
- A low-privilege user can silently become a full admin, exposing all API keys, model configs, and prompt history across your entire LiteLLM deployment.

CVE-2026-9089
NVDThe ConnectWise Automate agent doesn't fully verify that plugins and self-update payloads are authentic. An attacker with network access (for example, through a man-in-the-middle position or compromised update source) could swap in a malicious component. Since Automate agents run with SYSTEM privileges on managed endpoints, this is a serious supply-chain risk. CVSS 8.8, no known exploitation yet.
- Affected estate
- MSPs and IT teams running ConnectWise Automate agents on managed endpoints, prior to Automate 2026.5
- How to check
- In the Automate Control Center, check Help > About for the server version. On endpoints, check the Automate agent version in Add/Remove Programs or via the agent tray icon.
- Included because
- supply-chain vector; agents run as SYSTEM; widely deployed by MSPs; high CVSS
- Action
- Upgrade the Automate server to 2026.5 and confirm all agents pull the updated version.
- Why it matters
- Automate agents run as SYSTEM on every managed machine. A forged update could give an attacker code execution across your entire managed fleet.

CVE-2026-34910
NVDThis is as bad as it gets. A network-reachable attacker can exploit an input validation failure on UniFi OS devices to inject and execute arbitrary commands, no authentication required. CVSS 10.0. If your UniFi gear is internet-facing or reachable from an untrusted network, treat this as an emergency.
- Affected estate
- Anyone running UniFi OS devices (Dream Machine, Dream Router, Cloud Gateway, NVR, or other UniFi consoles) reachable from untrusted networks
- How to check
- Log into each UniFi console's Settings > System and check the UniFi OS version. Also run a network scan to identify any UniFi devices exposed on public IPs.
- Included because
- unauthenticated; network-reachable; CVSS 10.0; common network infrastructure; command injection
- Action
- Apply the latest UniFi OS firmware immediately. If you can't patch right now, firewall off management interfaces from untrusted networks.
- Why it matters
- Unauthenticated command injection at the OS level on your network gateway means full device takeover and potential pivot into your entire network.
