The latest commit on main is supported. Fixes land there; there are no backport branches and no maintained older releases.

Report privately through GitHub: open the Security tab of https://github.com/Jovan1666/dsh-commandcode-quota and choose Report a vulnerability. If that channel is not available to you, open a normal issue that says only that you have a security report and how to reach you — put no details in the issue itself.

Say what you ran, what happened, and what you expected; a minimal reproduction is worth more than a long description. This is a personal project maintained in spare time, so expect an acknowledgement within a few days, and please hold public disclosure until a fix is out.

The API calls are four read-only GETs, all with your key: /alpha/whoami (account name, org id), /alpha/usage/summary (credits used this period, requests, tokens), /alpha/billing/credits (remaining credits, the 5-hour and weekly windows) and /alpha/billing/subscriptions (plan id, billing period). There is no other request and no public endpoint is read. Each endpoint degrades on its own: a failure is recorded in the report and shown on the card instead of being retried silently. Each endpoint also gets 30 seconds to answer — COMMANDCODE_QUOTA_TIMEOUT_MS moves that, between 1 s and 120 s — and a reading that misses the deadline is dropped and named in the report rather than replaced with an older number. A 200 response that carries the vendor's own failure envelope ({"success":false,…}) counts as a failed read too.

The per-model allowances in the settings panel come from those public docs pages, not from your account: a check sends HEAD first and downloads a page only when its ETag says the vendor changed it (about 200 KB, at most one check a day by default — COMMANDCODE_CATALOG_TTL_MS moves that). Only the parsed numbers are stored, never the page.

This plugin does not write any host config. It installs through DSH's own plugin mechanism — dsh plugin --profile web add …, with the bundle patch at the repository root registering the loader row — so the only thing that touches your profile is the host itself. To remove it, dsh plugin --profile web remove dsh-commandcode-quota; to clear the cached snapshot too, delete $DSH_HOME/dsh-commandcode-quota/.

The card runs inside the host's renderer, so a bug here is a bug in a trusted context. The client touches the DOM for exactly two things: injecting one stylesheet keyed .ccq-, and rendering the card. It sends no request of its own — it asks the host over the same-origin /api transport (fenced to loopback, browser-session cookie required), and the host makes the upstream call. No localStorage, no cookies, no direct network calls. Report anything that lets a server response reach the DOM as markup rather than as text.

Your Command Code key is discovered in this order, and used for nothing except the Authorization header of the four requests above:

1. An explicitly passed key — the CLI's --key.
2. Discovered from your own DSH configuration: any provider route whose baseURL points at commandcode.ai, read from $DSH_HOME/settings.yaml or a patch layer ($DSH_HOME/cordis.patch.yml, $DSH_HOME/profiles/<name>/cordis.patch.yml — the desktop app keeps its settings there). The plugin reads that route's literal apiKey, or its apiKeyEnv resolved through the environment and $DSH_HOME/.credentials.yaml.
3. Environment variables COMMANDCODE_API_KEY, COMMAND_CODE_API_KEY, CMD_API_KEY, then any variable whose name contains commandcode. The exceptions are this plugin's own COMMANDCODE_QUOTA_TIMEOUT_MS and COMMANDCODE_CATALOG_TTL_MS, which are millisecond counts and are never read as keys.
4. The same names inside $DSH_HOME/.credentials.yaml (refs.<NAME>).
5. ~/.commandcode/auth.json, the official command-code CLI's login state.

A key is never written to a log, to the cache, or into anything the plugin renders — the browser only ever receives the normalized report. Prefer the environment variable over a literal in a config file that might get committed. If you believe a key of yours is exposed, revoke it in your Command Code account first — that is the only step that actually helps.

In scope: anything in this repository that leaks a credential, sends data anywhere other than https://api.commandcode.ai, writes outside the paths listed here, or turns an untrusted input (a settings file, an API response, a config value) into code execution.

Out of scope: the Command Code API itself; DeepSeek Harness and its plugin mechanism; and anything that requires an attacker who already holds your key or your shell.

The plugin requires dsh >= 0.1.5-rc.1 and the web profile. On an older host the plugin does not load, which is the intended failure — better a plugin that refuses than a card that renders nothing.
