SCA: security update for cloakbrowser (GHSA-mf33-gv72-w2h5)

high Tenable Cloud Security Plugin ID 442044

Description

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

 - CloakBrowser is a tool to bypass bot detection tests. Prior to version 0.3.28, the cloakserve CDP
 multiplexer uses the user-supplied fingerprint query parameter directly as a filesystem path component
 when creating Chrome profile directories. An unauthenticated attacker who can reach the cloakserve port
 can supply a crafted fingerprint value containing path traversal sequences to resolve user_data_dir
 outside the configured data_dir. When Chrome fails to start or the process is cleaned up, shutil.rmtree()
 deletes the traversed path, resulting in arbitrary directory deletion. Additionally, cloakserve bound to
 0.0.0.0 by default, making it network-exposed. This issue has been patched in version 0.3.28.
 (CVE-2026-45727)

Solution

Update the cloakbrowser library and its related packages to version 0.3.28 or later.
