SCA: security update for obsidian-tc (GHSA-737x-cwfr-5vvc)

high Tenable Self-Hosted Container Security Plugin ID 477171

Description

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

 - obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. From 1.13.0
 until 1.31.4, on a Streamable HTTP deployment with `auth.jwtSecret` configured and a 2026-07-28-era client
 declaring `elicitation.form` support, a dispatch-gated tool call offered an `inputRequired` confirmation
 could still complete after the human declined or cancelled, or the elicitation response was omitted or
 malformed, provided the client echoed the validly bound `requestState` on resubmission. The server trusted
 an authentic, call-bound state as proof of approval even though that state was minted before the
 `elicitation/create` leg was asked and proved only that the resubmission belonged to the same call. A
 client behaving incorrectly or under an attacker's control could therefore execute dispatch-gated
 destructive vault operations without the human's approval, while still requiring the caller's ordinary
 tool permissions. Only tools marked `destructive: true` or requiring a scope with a human-in-the-loop
 floor were reachable through this bypass. The sixteen handler-side conditionally gated tools, including
 `write_note` overwrite and `move_note`, did not read elicitation state on the modern wire and let neither
 approval nor decline through that path. Affected deployments using stdio or leaving `auth.jwtSecret` unset
 instead used the CLI `elicit_token` fallback and did not offer this `requestState` round trip. The fix
 does not prevent a malicious client from reporting a fabricated approval, because the server cannot verify
 that the client displayed the form or that a human saw it. This issue is fixed in version 1.31.4.
 (CVE-2026-115477)

Solution

Update the obsidian-tc library and its related packages to version 1.31.4 or later.
