CVE-2022-31051medium · fixedCVSS 4.4

Exposure of Sensitive Information to an Unauthorized Actor in semantic-release

### Impact _What kind of vulnerability is it? Who is impacted?_ Secrets that would normally be masked by semantic-release can be accidentally disclosed if they contain characters that are excluded from uri encoding by [encodeURI](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURI). Occurrence is further limited to execution contexts where push access to the related repository is not available without modifying the repository url to inject credentials. ##

Affected: >= 17.0.4Fixed in 19.0.3source →

CVE-2020-26226high · fixedCVSS 8.1

Secret disclosure when containing characters that become URI encoded

### Impact Secrets that would normally be masked by `semantic-release` can be accidentally disclosed if they contain characters that become encoded when included in a URL. ### Patches Fixed in v17.2.3 ### Workarounds Secrets that do not contain characters that become encoded when included in a URL are already masked properly.

Token Optimizer MCP

Cut what your AI coding agent costs without cutting what it gets done.
Hooks, a proxy, and an MCP server for Claude Code, Codex, Copilot, Gemini and 12 more clients.

Quick start · How it works · Benchmarks · All 16 clients · Reference · Changelog

On SWE-bench Verified, Claude Code with the plugin in its default mode solved the same tasks as Claude Code without it, at 0.71× the cost (7 of 7 resolved in both arms; across nine runs, 84 tasks resolved without the plugin and 83 with it). It gets there by stopping the waste agents make on their own: re-reading files that have not changed, dumping whole files to see three lines, unbounded searches, and re-deriving what an earlier session already worked out. Everything runs locally. No account, no hosted service, and telemetry is off unless you opt in twice.

The local dashboard: one ledger for every agent, every saving, and what the optimizer itself cost.

Quick start

Claude Code. Install the plugin rather than the bare MCP server: the plugin's hooks do the saving, while the server alone only offers tools the model can ignore.

/plugin marketplace add ooples/token-optimizer-mcp
/plugin install token-optimizer@token-optimizer
/reload-plugins

You need Node.js 22.14 or later on Claude Code's PATH, and Claude Code 2.1.139 or later. Then check it works:

npx token-optimizer-doctor

The doctor feeds a synthetic payload to the real hook and confirms a large read is handled. Every failure names its own fix.

Codex, Copilot CLI, Gemini CLI, Cursor and the rest. Every client runs the same server, npx -y @ooples/token-optimizer-mcp@latest. Ready-made configuration for each one is in src/integrations/, and docs/INSTALLATION.md walks through all sixteen.

Requirements and what happens without them

Node.js 22.14.0 or later, for the hooks and the MCP server. node must be on the PATH of the client process. If you just installed Node.js or Git, start the client again from a new terminal so it picks up the new PATH.
Claude Code 2.1.139 or later. The hooks use the exec form ("command": "node", "args": [...]). An older Claude Code ignores args, so the hooks silently do nothing; the doctor report
