GitHub Vulnerability Alerts

CVE-2025-66414

The Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default for HTTP-based servers. When an HTTP-based MCP server is run on localhost without authentication with StreamableHTTPServerTransport or SSEServerTransport and has not enabled enableDnsRebindingProtection, a malicious website could exploit DNS rebinding to bypass same-origin policy restrictions and send requests to the local MCP server. This could allow an attacker to invoke tools or access resources exposed by the MCP server on behalf of the user in those limited circumstances.

Note that running HTTP-based MCP servers locally without authentication is not recommended per MCP security best practices. This issue does not affect servers using stdio transport.

Servers created via createMcpExpressApp() now have this protection enabled by default when binding to localhost. Users with custom Express configurations are advised to update to version 1.24.0 and apply the exported hostHeaderValidation() middleware when running an unauthenticated server on localhost.

CVE-2026-0621

Impact

A ReDoS vulnerability in the UriTemplate class allows attackers to cause denial of service. The partToRegExp() function generates a regex pattern with nested quantifiers (([^/]+(?:,[^/]+)*)) for exploded template variables (e.g., {/id*}, {?tags*}), causing catastrophic backtracking on malicious input.

Who is affected: MCP servers that register resource templates with exploded array patterns and accept requests from untrusted clients.

Attack result: An attacker sends a crafted URI via resources/read request, causing 100% CPU utilization, server hang/crash, and denial of service for all clients.

Affected Versions

All versions of @modelcontextprotocol/sdk prior to the patched release.

Patches

v1.25.2 contains b392f02ffcf37c088dbd114fedf25026ec3913d3 the fix modifies the regex pattern to prevent backtracking.

Workarounds

  • Avoid using exploded patterns ({/id*}, {?tags*}) in resource templates
  • Implement request timeouts and rate limiting
  • Validate URIs before processing to reject suspicious patterns

Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)
  • yarn.lock is excluded by !**/yarn.lock, !**/*.lock

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Block Low
Potential code anomaly (AI signal): npm @humanwhocodes/retry is 100.0% likely to have a medium risk anomaly

Notes: The Retrier class implements a conventional, well-scoped retry mechanism with abort support and backoff-like scheduling. There is no evidence of malicious behavior, data exfiltration, or backdoors in this fragment. The primary security considerations relate to the trustworthiness of the host-provided function (fn) and the external timing constants that govern bail/retry behavior. Overall risk is moderate due to the possibility of executing arbitrary host code, but this is expected for a retry utility; no external communications or data leakage are evident here.

Potential code anomaly (AI signal): npm ajv is 100.0% likely to have a medium risk anomaly

Notes: The code represents a conventional, non-obfuscated part of AJV’s custom keyword support. No direct malicious actions are evident within this module. Security concerns mainly arise from the broader supply chain: the external rule implementation (dotjs/custom), the definition schema, and any user-supplied keyword definitions. The dynamic compilation path (compile(metaSchema, true)) should be exercised with trusted inputs. Recommended follow-up: review the contents of the external modules and monitor the inputs supplied to addKeyword/definitionSchema to ensure no unsafe behavior is introduced during validation or data handling.

Block Low
Potential code anomaly (AI signal): npm consola is 100.0% likely to have a medium risk anomaly

Notes: The analyzed code fragment is a feature-rich, standard Consola logging utility responsible for redirecting and managing log output with throttling, pausing, and reporter integration. There is no direct evidence of malicious activity, hardcoded secrets, or exfiltration within this snippet. However, the powerful I/O overrides pose privacy and data flow risks if reporters or downstream sinks are untrusted. The security posture hinges on trusted reporters and proper governance of the overall supply chain.

Potential code anomaly (AI signal): npm detect-libc is 100.0% likely to have a medium risk anomaly

Notes: The code represents a robust, multi-source libc detection utility for Linux, prioritizing filesystem data, then runtime reports, and finally command-based inference. It shows no malicious behavior and aligns with expected patterns for environment introspection. The main improvement areas are strengthening error visibility and handling edge cases where outputs differ from standard expectations.

Block Low
Potential code anomaly (AI signal): npm hardhat is 100.0% likely to have a medium risk anomaly

Notes: The code implements a subprocess-based transport to offload event sending. While this can reduce main-process dependencies, it creates a cross-process data path that exposes the serialized event via environment variables to an external subprocess. The subprocess script (not present here) becomes a critical trust boundary. Without inspecting the subprocess implementation and package contents, there is a non-trivial risk of data leakage or tampering via the external process. No explicit malware detected in this fragment, but the design warrants careful review of the subprocess code and supply chain integrity.

Block Low
Potential code anomaly (AI signal): npm ignore is 100.0% likely to have a medium risk anomaly

Notes: The code fragment represents a conventional, well-structured path-ignore utility with caching and recursive parent-directory evaluation. Windows path normalization is present for compatibility but does not indicate malicious intent. No indicators of data leakage, external communication, or covert backdoors were found. Security impact primarily revolves around correct ignore semantics rather than intrinsic vulnerabilities. The component remains appropriate for use in a broader security-conscious pipeline if used with careful awareness of what is being ignored.

Potential code anomaly (AI signal): npm object-hash is 100.0% likely to have a medium risk anomaly

Notes: Conclusion: The code appears to be a standard, open-source-like object hashing/serialization utility with streaming capabilities. No active malicious behavior detected within this fragment. Minor issues (typos, blob handling edge-case, and potential performance considerations for large inputs) should be addressed to reduce risk in supply-chain contexts. Overall security risk remains moderate and workload/usage controls should govern integration.

Potential code anomaly (AI signal): npm openai is 100.0% likely to have a medium risk anomaly

Notes: The script itself is not evidently malicious but poses a moderate-to-high supply-chain risk: it invokes npx to download and execute a GitHub-hosted tarball and passes a local migration-config.json path and the process environment to the remote code. That remote code could perform arbitrary actions, read local configuration or environment secrets, or exfiltrate data. Mitigations: avoid using tarball URLs in runtime invocations, pin to vetted packages in package.json, verify integrity (checksums/signatures), vendor the migration tool or require an explicit local installation, and avoid passing sensitive file paths or environment variables to untrusted code.

Potential code anomaly (AI signal): npm proxy-addr is 100.0% likely to have a medium risk anomaly

Notes: The code is a standard, well-scoped IP trust utility (proxy-addr) with no evidence of malicious behavior. It reads IPs from request headers, validates and normalizes them, and applies a trust policy to determine the client address. No backdoors, exfiltration, or dangerous operations are present. The security posture appears acceptable for its intended purpose when used as a dependency in an Open Source project.

Potential code anomaly (AI signal): npm resolve is 100.0% likely to have a medium risk anomaly

Notes: This manifest uses a non-registry, relative-path dependency ('resolve': '../../../') which is a significant supply-chain risk because it allows arbitrary local code to be pulled in and executed without registry protections. Combined with the 'lerna bootstrap' postinstall script (which can trigger other lifecycle scripts across the monorepo), this setup increases the chance of untrusted code execution and other malicious behavior. Inspect the target of the relative path, all bootstrap-linked packages, and any lifecycle scripts before running npm install in an untrusted environment.

Potential code anomaly (AI signal): npm rimraf is 100.0% likely to have a medium risk anomaly

Notes: The rimraf module analyzed appears to be a conventional, dependable recursive deletion utility with thoughtful cross-platform safeguards and backoff strategies.

Block Low
Potential code anomaly (AI signal): npm rollup-plugin-terser is 100.0% likely to have a medium risk anomaly

Notes: This file is a terser wrapper that unsafely evaluates a caller-supplied string to produce options. The code itself contains no explicit exfiltration, hard-coded credentials, or network calls, and appears non-obfuscated. However, eval(optionsString) is a high-severity issue: if optionsString can be influenced by an attacker, the application can be fully compromised (RCE). Replace eval with safe parsing and validate inputs. Avoid returning mutable objects from evaluated input.

Block Low
Potential code anomaly (AI signal): npm rxjs is 100.0% likely to have a medium risk anomaly

Notes: The code is a conventional, well-scoped implementation of an RxJS-like concat operator. No malicious behavior, data exfiltration, or suspicious I/O detected in this fragment. Security risk is low; malware likelihood is negligible for this isolated operator function.

Block Low
Potential code anomaly (AI signal): npm synckit is 100.0% likely to have a medium risk anomaly

Notes: The code is a sophisticated, legitimate utility for managing worker threads with various TypeScript runtimes and global shims. It does not exhibit explicit malicious behavior, hardcoded secrets, or standard malware patterns. The main security considerations relate to the safe handling of workerPath/globalShims inputs and ensuring that only trusted, validated worker code is executed in worker contexts. Overall risk is moderate due to the dynamic nature of code loading, but the fragment itself is a standard, non-malicious utility module.

Block Low
Potential code anomaly (AI signal): npm terser is 100.0% likely to have a medium risk anomaly

Notes: Conclusion: The fragment is a benign static list of DOM/Web API identifiers used for tooling purposes (e.g., property enumeration, whitelist checks, or code generation). There is no evidence of malicious behavior, data exfiltration, or backdoors within this fragment alone. Overall security risk is low for this isolated piece; assessment should consider how the list is used in the broader codebase.

Block Low
Potential code anomaly (AI signal): npm zod is 100.0% likely to have a medium risk anomaly

Notes: No explicit network exfiltration, reverse shell, or credential theft is present in this fragment. However, the code assembles and compiles arbitrary code via the Function constructor and invokes passed-in functions immediately (twice). That behavior constitutes a strong dangerous primitive (arbitrary code execution) which can be abused if any inputs (strings or args) are attacker-controlled. Treat this module as risky in threat models where inputs are not fully trusted; review call sites and sanitize/validate inputs or avoid dynamic evaluation.
