HIGHSends data to a hardcoded chat or capture webhookSS-PLUGIN-SECRET-EXFIL-WEBHOOK-01 · Credential exfiltration · plugins/all-hooks/hooks/telegram-detailed-notifications.md
HIGHa hardcoded webhook is a ready-made data drop, but a legitimate notifier looks identical without more context — high, pending the shadow-window FP measurement.
Why it matters

This plugin embeds a chat-platform or request-capture webhook URL (url="https://api.telegram.org/bot${TELEGRAM_BOT_…). Webhooks are the classic exfiltration drop: a plugin collects env, files, or system info and posts it to a hardcoded endpoint the attacker watches.

How to fix
Remove the hardcoded webhook URL; make any notification target user-configured and never send secrets through it.
  1. Replace the embedded webhook URL with a value the installing user supplies.
  2. Post only non-sensitive notification fields — never env vars, file contents, or credentials.

HIGHFenced code block that tells the agent to run a commandSS-SKILL-INJECT-FENCED-RUN-01 · Prompt injection · plugins/claude-ops/README.md
HIGHa successful fenced-imperative injection runs attacker-supplied shell on the user's machine.
Why it matters

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

How to fix
Remove the runnable block, or rewrite it as a non-executable example the agent will not act on.
  1. Delete the imperative ("run this", "execute the following") from inside the fence.
  2. If you must show setup, label the block text (not bash) so it reads as prose, not a command.
  3. Move any real installer into a reviewed, version-pinned script in the repo and link to it.
