CVE-2025-54386

Traefik's Client Plugin is Vulnerable to Path Traversal, Arbitrary File Overwrites and Remote Code Execution

Published Aug 1, 2025 CVSS 4.0 · 7.3 High EPSS 1.4% KEV · Not listed
Description
Traefik is an HTTP reverse proxy and load balancer. In versions 2.11.27 and below, 3.0.0 through 3.4.4 and 3.5.0-rc1, a path traversal vulnerability was discovered in WASM Traefik’s plugin installation mechanism. By supplying a maliciously crafted ZIP archive containing file paths with ../ sequences, an attacker can overwrite arbitrary files on the system outside of the intended plugin directory. This can lead to remote code execution (RCE), privilege escalation, persistence, or denial of service. This is fixed in versions 2.11.28, 3.4.5 and 3.5.0.
