NVD description

Podman Desktop is a graphical tool for developing on containers and Kubernetes. Prior to 1.26.2, an unauthenticated HTTP server exposed by Podman Desktop allows any network attacker to remotely trigger denial-of-service conditions and extract sensitive information. By abusing missing connection limits and timeouts, an attacker can exhaust file descriptors and kernel memory, leading to application crash or full host freeze. Additionally, verbose error responses disclose internal paths and system details (including usernames on Windows), aiding further exploitation. The issue requires no authentication or user interaction and is exploitable over the network. This vulnerability is fixed in 1.26.2.

Disclosure
A developer tool on your network just became a remote attack vector 🌐 Pentera Labs researcher Nir Chako discovered CVE-2026-34045 in Podman Desktop, a tool with 3M+ downloads and a fresh spot in the CNCF Sandbox. The issue? A background service intended for localhost was silently binding to port 44000 on all network interfaces. No authentication. No connection limits. No timeouts. That's all an attacker needs. With just network access, a remote unauthenticated attacker could: → Crash the host entirely using a Slowloris-style connection flood → Extract internal usernames and filesystem paths from unhandled error responses As always, the emerging technologies of today are the mainstream of tomorrow. It’s better to close the security issues at this stage, before the blast radius becomes too big to handle. OWASP's Top 10:2025 now officially ranks developer workstations among the most critical attack surface areas in the software supply chain. This CVE is a live example of exactly why. If you're running Podman Desktop, update to v1.26.2 (or newer) now. Full research here👇 https://okt.to/xsCqVg
