CVE-2026-55629
Overview
CVE-2026-55629 is a known-severity vulnerability. It was published on July 16, 2026.
Technical Description
Whistle is an HTTP, HTTP2, HTTPS, and WebSocket debugging proxy. Prior to 2.10.3, lib/service/service.js handles GET /cgi-bin/temp/get by reading req.query.filename, joining it to TEMP_FILES_PATH only when it matches the temporary file pattern, and otherwise passing the user-supplied filename directly to getFile, allowing a remote attacker to read arbitrary files such as /etc/passwd. This issue is reported as fixed in version 2.10.3.
