How to Fix GHSA-7q9x-8g6p-3x75

To remediate this vulnerability, upgrade all affected @grackle-ai/server dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@grackle-ai/server fixed: 0.70.1 
npm install @grackle-ai/server@0.70.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @grackle-ai/server

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-7q9x-8g6p-3x75, inspect your project dependencies using npm:

npm ls @grackle-ai/server

Analyze the terminal output to locate any version of @grackle-ai/server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.70.1), your application is affected.

Note: The npm ls @grackle-ai/server command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In @grackle-ai/server, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The `renderPairingPage()` function embeds the `error` parameter directly into HTML without escaping: ```typescript const errorHtml = error ? `<p style="color:#e74c3c">${error}</p>` : ""; ``` All current call sites pass hardcoded strings, so this is **not exploitable today**. However, the function is architecturally fragile — if a future code change passes user-controlled or dynamic content into the error parameter, it would create an XSS vulnerability. The `renderAuthorizePage()` function in the same file correctly uses `escapeHtml()` for dynamic content, making this an inconsistency. **Affected code:** - `packages/server/src/index.ts:64-89` — `renderPairingPage()` with unescaped error interpolation - Compare: `packages/server/src/index.ts:130` — `renderAuthorizePage()` correctly uses `escapeHtml()` ### Patches v0.70.1 **Fix:** Apply `escapeHtml()` to the error parameter: ```typescript const errorHtml = error ? `<p style="color:#e74c3c">${escapeHtml(error)}</p>` : ""; ``` ### Workarounds No workaround needed — all current callers pass hardcoded strings. ### Resources - CWE-79: Improper Neutralization of Input During Web Page Generation - File: `packages/server/src/index.ts`
