Fixes SOU-2526
Addresses CVE-2026-104850 (Dependabot alert #399). The MCP TypeScript SDK OAuth client could send credentials to an authorization server chosen by the MCP server. Affects
@modelcontextprotocol/sdk1.12.0 through 1.30.1, patched in 1.31.0.The lockfile was stale. Both existing ranges (
^1.29.0from@sourcebot/weband^1.25.0from@react-grab/mcp) already admit the patched version, so this is a lockfile refresh viayarn up -R @modelcontextprotocol/sdk. Nopackage.jsonchange and noresolutionsoverride. Both requesters now resolve to1.32.1(previously1.29.0and1.27.1).Note: Sourcebot uses the SDK's server APIs and
StreamableHTTPClientTransport. Per the advisory, any customOAuthClientProvidershould persist the newissuerfield. No such provider exists in this repo today.Validation:
yarn why @modelcontextprotocol/sdkshows only1.32.1.yarn workspace @sourcebot/web test: 148 files and 1511 tests pass.yarn workspace @sourcebot/web lintpasses.tsc --noEmit: no MCP-related errors. The remaining errors are pre-existing asset-import andutils.tserrors unrelated to this change.🤖 Generated with Claude Code
Note
Low Risk
Lockfile-only security patch with existing semver ranges; no custom OAuth client provider in the repo, so behavioral impact should be limited to the upstream SDK fix.
Overview
Security dependency bump for
@modelcontextprotocol/sdkto 1.32.1 (CVE-2026-104850), addressing an OAuth client issue where credentials could be sent to an authorization server chosen by the MCP server.There are no
package.jsonor application code changes—only a Yarn lockfile refresh that deduplicates prior resolved versions (1.27.1/1.29.0) so all consumers resolve to 1.32.1, plus an Unreleased changelog entry under Fixed.Reviewed by Cursor Bugbot for commit 048b3bd.
