Any authenticated non-admin who could use a shared tool could also read its source, including any user on the instance when a tool was shared publicly. Source is meant to be a writer-only tier: the list response schema deliberately omits it and source export sits behind its own permission. The read endpoints delivered it anyway.\n\n## Preconditions\n\n- Authentication enabled (`WEBUI_AUTH=true`, default) and plugins enabled (`ENABLE_PLUGINS=true`, default).\n- The attacker is an authenticated non-admin without the `workspace.tools` permission and without a write grant on the tool.\n- A tool is shared with a read grant to the attacker, to one of their groups, or to all users (`user:*`).\n\nDeployments that share no tools, or share them only with users who already hold write access, are not affected.\n\n## Impact\n\nA non-admin obtains another user's server-side tool source. Tool source commonly embeds hard-coded API keys, credentials and internal service URLs, so the practical loss frequently extends past the code itself.
