The issue identifies the exact dependency and affected Angular CLI branches, and links an open pull request (#34456). Read the dependency declarations for the v20 and v21 branches and compare them with the fix described in #34263. Done means the dependency is updated to a patched version on both branches and the reported npm audit vulnerability no longer applies.

Description

@modelcontextprotocol/sdk versions before 1.32.0 are affected by four advisories published on 2026-10-20, all patched in 1.32.0:

https://github.com/advisories/GHSA-22jm-h49p-29qw (CVE-2026-111767, CVSS 8.6): "MCP TypeScript SDK: Experimental tasks were not tied to the session that created them", affected >= 1.24.0, < 1.32.0
https://github.com/advisories/GHSA-46jr-4wx8-v453 (CVE-2026-111768, CVSS 7.5): "MCP TypeScript SDK: One HTTP request within the default size limit could exhaust server memory during validation", affected >= 1.3.0, < 1.32.0
https://github.com/advisories/GHSA-6prh-2h8m-c8cw (CVE-2026-111769, CVSS 6.5): "MCP TypeScript client SDK: HTTP client transports and OAuth requests followed cross-origin redirects and re-sent custom headers and request bodies", affected < 1.32.0
https://github.com/advisories/GHSA-rvq5-wwqv-78pq (CVE-2026-111771, CVSS 6.8): "MCP TypeScript SDK: Server bearer authentication accepted tokens issued for another service", affected >= 1.6.0, < 1.32.0

Both LTS branches pin a vulnerable version exactly (locked on, no update allowed):

v21 LTS: @angular/cli 21.2.26 through 21.2.27 (latest) depend on @modelcontextprotocol/[email protected] (earlier 21.2.x pinned 1.26.0 and 1.30.0, also affected)
v20 LTS: @angular/cli 20.3.39 through 20.3.40 (latest) depend on @modelcontextprotocol/[email protected] (earlier 20.3.x pinned 1.17.3, 1.24.0, 1.25.2, 1.26.0 and 1.30.0, also affected)

v22 (22.2.x) is not affected: it depends on @modelcontextprotocol/server instead, pinned to the patched 2.3.1 since 22.2.2 (22.2.0 and 22.2.1 pinned 2.0.0, updated in #34266).

The CLI only uses McpServer over stdio, so these do not look reachable through ng mcp, but the exact pin makes npm audit flag every install. npm's advisory feed only has GHSA-22jm-h49p-29qw and GHSA-6prh-2h8m-c8cw so far, so the audit output below lists those two.

The fix would be bumping @modelcontextprotocol/sdk to 1.32.1 (latest, same code as 1.32.0) on both branches, as was done for #34263 (#34264 / #34265).

Minimal Reproduction

npm install @angular/cli@21 (or @angular/cli@20)
npm audit

Exception or Error
