CVE-2026-55156 Token Optimizer MCP: Unauthenticated Path Traversal in Dashboard Session Log API Endpoints

Token Optimizer MCP measures token savings per AI coding agent, optimizes context, and shares a live local knowledge graph across 16 CLI clients. Prior to version 5.1.0, the dashboard HTTP server in token-optimizer-mcp exposes /api/session-summary and /api/session-events with no authentication...

CVE-2026-101909 Axios: Prototype Pollution Gadget in axios toFormData Options

Axios is a promise-based HTTP client for the browser and Node.js. From 0.28.0 until 0.34.0 and 1.15.1 until 1.20.0, ToFormData processes inherited serialization options and visitor properties supplied through prototype pollution. A separate same-process prototype-pollution flaw supplies inherited...

CVE-2026-101909

The Axios promise-based HTTP client (versions 0.28.0 to 0.34.0 and 1.15.1 to 1.20.0 ) contains a Prototype Pollution Gadget in the toFormData options. The vulnerability exists because ToFormData processes inherited serialization options and visitor properties. This allows an attacker who has alre...

CVE-2026-101908

Axios is a promise-based HTTP client for the browser and Node.js. From 1.7.0 until 1.20.0, the fetch adapter constructs a Request with sanitized resolvedOptions but then calls fetch with the original fetchOptions. A separate same-process prototype-pollution flaw populates Object.prototype.headers...

CVE-2026-101908

The Axios HTTP client (versions 1.7.0 through 1.20.0 ) contains a prototype pollution gadget within its fetch adapter . The vulnerability occurs because the adapter constructs a Request object using sanitized options but then invokes the fetch function using the original, unsanitized fetchOptions...

CVE-2026-101907 Axios: maxRedirects: 0 is not enforced by the fetch adapter, allowing redirect-based SSRF

Axios is a promise-based HTTP client for the browser and Node.js. From 1.17.0 until 1.20.0, the fetch adapter bypasses the maxRedirects: 0 redirect policy. An Axios request uses the fetch adapter with maxRedirects set to zero and receives a redirect response. The underlying fetch implementation...

CVE-2026-101907

The Axios promise-based HTTP client (versions 1.17.0 through 1.20.0 ) contains a vulnerability where the fetch adapter fails to enforce the maxRedirects: 0 policy. When an Axios request using this adapter receives a redirect response, the underlying fetch implementation follows the redirect inste...

CVE-2026-101906

Axios is a promise-based HTTP client for the browser and Node.js. From 1.15.0 until 1.20.0, Axios shouldBypassProxy applies a quadratic trailing-dot regular expression to redirect hostnames. HTTPPROXY or HTTPSPROXY is configured, NOPROXY or noproxy is non-empty, redirects are followed, and a...
