SCA: security update for chrome-devtools-mcp (GHSA-3pvj-jv98-qhjq)

medium Tenable Cloud Security Plugin ID 443388

Description

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

- Chrome DevTools for agents (chrome-devtools-mcp) lets your coding agent control and inspect a live Chrome
browser. From 0.20.0 until 1.1.0, The chrome-devtools-mcp daemon writes its PID file with
fs.writeFileSync() to a deterministic runtime path. On typical macOS environments, and on Linux sessions
where $XDG_RUNTIME_DIR is unset, that runtime path falls back to /tmp/chrome-devtools-
mcp-<uid>/daemon.pid. Because the write does not use O_NOFOLLOW, a local low-privilege user on the same
POSIX host can pre-create /tmp/chrome-devtools-mcp-<victim_uid>/daemon.pid as a symlink to a file writable
by the victim. When the victim later starts daemon mode, fs.writeFileSync() follows the symlink and
truncates the target file to the daemon PID string. This vulnerability is fixed in 1.1.0. (CVE-2026-53765)

Solution

Update the chrome-devtools-mcp library and its related packages to version 1.1.0 or later.
