SCA: security update for code-server (GHSA-p483-wpfp-42cj)

high Tenable Self-Hosted Container Security Plugin ID 425955

Description

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

- code-server runs VS Code on any machine anywhere through browser access. Prior to version 4.99.4, a
maliciously crafted URL using the proxy subpath can result in the attacker gaining access to the session
token. Failure to properly validate the port for a proxy request can result in proxying to an arbitrary
domain. The malicious URL `https://<code-server>/proxy/[email protected]/path` would be proxied to
`[email protected]/path` where the attacker could exfiltrate a user's session token. Any user who runs code-
server with the built-in proxy enabled and clicks on maliciously crafted links that go to their code-
server instances with reference to /proxy. Normally this is used to proxy local ports, however the URL can
reference the attacker's domain instead, and the connection is then proxied to that domain, which will
include sending cookies. With access to the session cookie, the attacker can then log into code-server and
have full access to the machine hosting code-server as the user running code-server. This issue has been
patched in version 4.99.4. (CVE-2025-47269)
