SCA: security update for github.com/esm-dev/esm.sh (GHSA-3636-h3vx-6465)

high Tenable Self-Hosted Container Security Plugin ID 441789

Description

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

- esm.sh is a no-build content delivery network (CDN) for web development. In 137 and earlier, the legacy
router first retrieves a response from legacyServer, parses the incoming request path, and ultimately
writes the data to storage via buildStorage.Put. The router concatenates the path components without
sanitizing them, producing a storage key. When this key is used, the underlying file system resolves the
relative segments and writes the file to the specified path. Thus an attacker can craft a request that
writes data to arbitrary locations on the server. (CVE-2026-44593)

Solution

Update the github.com/esm-dev/esm.sh library and its related packages to version 0.0.0-20260508100112-1960055e1d53 or later.
