Podman Desktop WebView Server Exposed_CVE-2026-34045

8.2 / 10

HIGH

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H

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.
