SCA: security update for whistle (GHSA-3vfr-4gwf-qxfp)

high Tenable Self-Hosted Container Security Plugin ID 446271

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-55629)

Solution

Update the whistle library and its related packages to version 2.10.3 or later.
