SCA: security update for omniroute (GHSA-hf57-cqmx-p4gr)

critical Tenable Cloud Security Plugin ID 447918

Description

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

 - OmniRoute is an open-source AI gateway providing a single endpoint for multiple model providers. In 3.8.49
 and earlier, the OmniRoute POST /api/acp/agents custom ACP agent endpoint accepted attacker-controlled
 binary and versionCommand values and used only a self-consistency check before execFileSync executed the
 selected interpreter and arguments. The same request called refreshAgentCache, and resolveVersionProbe
 accepted the matched command before the execFileSync sink ran it. The tokenizeVersionCommand function and
 DISALLOWED_VERSION_COMMAND_CHARS filter rejected a limited set of shell metacharacters but still allowed
 interpreter evaluation arguments. The isAuthenticated function relied on isAuthRequired, which accepted
 anonymous requests when requireLogin was false, while api/acp/ was absent from LOCAL_ONLY_API_PREFIXES and
 SPAWN_CAPABLE_PREFIXES. With requireLogin=false or during a fresh-instance bootstrap window, a remote
 anonymous request could supply an interpreter evaluation argument and execute arbitrary code in the server
 container. With requireLogin=true and a configured management password, exploitation instead required a
 management session or management-scoped API key. No fixed version is available as of this review.
