Nearly 1 in 10 Exposed LiteLLM Gateways Accepted the Example "sk-1234" Admin Key

Wiz found 294 of 3,074 internet-facing LiteLLM gateways accepted the documented default admin key sk-1234, exposing provider API keys and cloud IAM credentials.

Wiz Research's February Shodan scan found 3,074 LiteLLM gateways, 294 of which accepted the setup guide's sk-1234 admin key; 191 had no master key set and would accept any credential. The master key doubles as the authentication switch, and before 1.82.0-stable a gateway started without one granted every request full admin rights, exposing stored provider API keys, prompts, and MCP-connected tools. A documented pass-through endpoint lacks checks against private and cloud metadata addresses, letting an admin-key holder retrieve cloud IAM credentials, though no real-world abuse is reported. Related LiteLLM flaws include CVE-2026-59821 (disputed guardrail code execution), CVE-2026-59822 (CVSS 8.8, added to CISA KEV on September 2 and observed against Wiz honeypots), and CVE-2026-42271, used to install a cryptominer.

FreeIPA Flaw Chain Lets Anonymous Clients Create Reusable Administrator Credentials

Critical FreeIPA flaw chain (CVE-2026-76578, CVSS 9.8) lets anonymous clients create reusable admin credentials on default installs; fixed in 4.13.4.

Red Hat warns that chaining FreeIPA's CVE-2026-76578 (CVSS 9.8) with a 389 Directory Server flaw (CVE-2026-76560, CVSS 7.5) lets an anonymous client write a Kerberos identity into the directory and land in the administrators group on default installations; Red Hat reproduced the chain twice, including on a machine with no access at all. FreeIPA 4.13.4 fixes both flaws, and fourteen 389-ds advisories shipped September 8, with RHSA-2026:64785 rated critical. A separate flaw, CVE-2026-79678 (CVSS 8.1), allows reading the server's environment variables one at a time via a Python eval() in idp-add, potentially exposing Directory Manager and administrator passwords in container installs. No real-world exploitation has been reported.

Next.js Patches Critical AVIF and Windows Flaws Enabling Unauthenticated RCE

Vercel patches two critical Next.js unauthenticated RCE flaws: a libheif AVIF heap overflow (CVSS 9.5) and a Windows path traversal (CVE-2026-75604).

Vercel patched two critical Next.js flaws enabling unauthenticated remote code execution: a heap buffer overflow in libheif's AVIF image scaling (GHSA-2xp9-vwfh-vxw4, CVSS v4 9.5) and a Windows path traversal (CVE-2026-75604, CVSS 9.0). The AVIF flaw affects only sites explicitly enabling AVIF optimization and overwrites roughly 16,384 bytes past the buffer; the path traversal affects Windows-hosted Next.js deployments on versions 13.4-15.5.23 and 16.0-16.3.2. Fixes shipped in Next.js 15.5.24 and 16.3.3 on August 25, 2026, with the AVIF researchers releasing a Python PoC demonstrating RCE on multiple applications. No exploitation had been reported as of August 27, 2026.
