SCA: security update for serena-agent (GHSA-37h2-6p4f-mp3q)

high Tenable Cloud Security Plugin ID 444528

Description

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

 - Serena is a powerful MCP toolkit for coding that provides semantic retrieval and editing capabilities.
 Prior to v1.5.2, Serena's built-in web dashboard exposes an unauthenticated Flask API on a fixed,
 predictable port, with no authentication, no CSRF protection, and no Host header validation. A DNS
 rebinding attack allows a malicious webpage to reach this API from any browser and write arbitrary content
 to the agent's persistent memory store, which the agent reads and acts on autonomously. Combined with
 execute_shell_command using shell=True, this creates a remote code execution chain requiring only that the
 victim visit a malicious webpage while Serena is running. This issue is fixed in version v1.5.2.
 (CVE-2026-49471)

Solution

Update the serena-agent library and its related packages to version 1.5.2 or later.
