Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% build/bitrix24/client.js line 6-7 declares \`const BITRIX24\_WEBHOOK\_URL = process.env.BITRIX24\_WEBHOOK\_URL || 'https://sviluppofranchising.bitrix24.it/rest/27/wwugdez6m774803q/';\`. When the consumer fails to set BITRIX24\_WEBHOOK\_URL (typo, forgotten env var, default config), every MCP tool call performed by this server — task creation, comments, user enumeration, and the \`bitrix24\_attach\_files\_to\_task\` tool which reads arbitrary local file paths supplied as \`filePaths\` and base64-uploads them — is POSTed to a hardcoded third-party Bitrix24 portal (user 27, webhook secret \`wwugdez6m774803q\`) controlled by an unrelated party. The package fails open rather than fail-closed: no warning, no error, no opt-in confirmation. The \`bitrix24\_attach\_files\_to\_task\` path is particularly severe because the MCP agent can be induced to read sensitive local files (configs, credentials, source) and forward their contents to that portal. Author metadata in package.json is the npm-init placeholder \`"Your Name"\`, indicating low maintainer accountability and matching the placeholder-metadata-plus-network pattern. This is the canonical silent-relay shape: caller-supplied data is silently routed through the package's API to a destination the caller did not choose. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepublishOnly - **Dependencies:** 3 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 3 - **Published dependency-graph edges:** 3 ### Published dependency entries - @modelcontextprotocol/sdk ^0.4.0 (Dependency) - node-fetch ^3.3.2 (Dependency) - zod ^3.22.4 (Dependency) ## Package metadata - **Package:** bitrix24-tasks-mcp-server - **Ecosystem:** npm - **Version:** 1.5.1 - **License:** MIT - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-09-14T01:36:52.596Z - **Known versions:** 8 - **Latest version:** 1.8.0 - **Appeal under review:** No - **Description:** Bitrix24 MCP server for tasks, projects, and users - **Author:** Your Name - **Maintainers:** chrome-consulting - **Keywords:** mcp, bitrix24, tasks, projects, automation - **Runtime engines:** npm: \>=8.0.0, node: \>=18.0.0 - **Artifact files:** 34 - **Artifact unpacked size:** 259,962 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
