To fix this kind of issue, user-controlled values should be sanitized before being written to logs. For plain-text logs, a common mitigation is to strip newline and carriage-return characters (and optionally other control characters) from user input before logging, so they cannot break the log format or inject additional lines. It’s also good practice to clearly delineate user input in log messages, but the primary concern here is removing line breaks.
In this file, the key problematic log is console.error('Facebook OAuth error:', error, errorDescription); where error (and similarly errorDescription) come from the request URL. The minimal, non-functional-change fix is to sanitize error and errorDescription just for logging, while still using their original values for redirects (since they end up in query parameters again and not in logs). We can introduce local sanitized variables, e.g. safeError and safeErrorDescription, that replace \r and \n with empty strings, and use those in the log call. This change only affects what is logged and not the behavior of the OAuth flow or redirects. No new imports or external libraries are necessary; String.prototype.replace is sufficient.
Concretely, in src/app/api/integrations/facebook/oauth/callback/route.ts, inside the if (error) { ... } block, we will replace the direct console.error call with one that uses sanitized versions of error and errorDescription, created by applying .replace(/[\r\n]/g, '') (only if they are non-null). All other code remains unchanged.

To fix the problem, sanitize user-controlled data before including it in log messages. Since the apparent log target is plain text (console.error), the main risk is newline and carriage-return characters that could cause log line splitting or injection. A minimal and safe fix is to strip \r and \n from errorDescription before logging it, while keeping the original behavior otherwise unchanged.
Concretely for this file:
- Introduce a sanitized version of
errorDescriptionright after it is read from the query string (around line 32–33), usingString.prototype.replaceto remove\rand\n. - Use this sanitized variable in the logging call at line 36 instead of the raw
errorDescription. - Do not change how
errorDescriptionis used to build redirect URLs; only the logging is of concern for log injection as described.
No new imports are required; standard string methods are sufficient.

In general, to fix this class of issues you must avoid passing untrusted data as the format string (or part of it). Instead, use a constant format string and pass untrusted data as additional arguments (for %s placeholders) or as separate arguments without formatting, or sanitize/escape % characters before including them in a format string.
Here, the minimal, behavior-preserving fix is to change the console.error call so that the format string is constant and productId is passed as a substitution argument. Currently:
console.error(`Failed to sync product ${productId}:`, error);If productId includes %d, %s, etc., this becomes a format string. We should change it to:
console.error('Failed to sync product %s:', productId, error);This keeps the same log content while ensuring that any % characters in productId are treated as data instead of directives. No new imports or helpers are needed; the change is local to src/lib/integrations/facebook/product-sync-service.ts around the catch block in syncProduct.

In general, to fix log injection where user input is interpolated into log messages, you either sanitize the user-controlled value (e.g., strip newlines and other control characters) or log a safe representation (like a JSON-encoded or truncated value) instead of the raw string. The core idea is that whatever you write to logs should not allow an attacker to introduce extra log entries or alter the structure of existing ones.
For this specific code, the primary issue is on line 205 in src/lib/integrations/facebook/product-sync-service.ts:
console.error(`Failed to sync product ${productId}:`, error);The best low-impact fix is to sanitize productId locally before including it in the log message. We can remove newline (\n) and carriage return (\r) characters, which are the key ones for log injection in text logs. To keep behavior unchanged for normal IDs, we only transform pathological values. A minimal change is to introduce a local safeProductId that strips these characters, and use that in the log line:
const safeProductId = productId.replace(/[\r\n]/g, '');
console.error(`Failed to sync product ${safeProductId}:`, error);This does not alter how productId is used elsewhere in the method (database queries, return values, etc.), so existing functionality remains intact; it only affects what is written to logs. No new imports or helpers are needed, since String.prototype.replace and regex literals are built-in.

General approach: Ensure user-controlled data cannot arbitrarily shape the URL used in outgoing requests. Since the origin (https://graph.facebook.com/v24.0) is already fixed, the main step is to validate and constrain orderId before interpolating it into the path. We should accept only the format that Facebook order IDs are expected to have (or at least a safe subset), and reject anything else with a clear error. This way, even if the static analyzer is conservative, the data is no longer “tainted” in a problematic way.
Best concrete fix without changing functionality:
- In
src/lib/integrations/facebook/order-manager.ts, add a small private helper method in theMetaOrderManagerclass to validate order IDs. For example, enforce they are non-empty and contain only alphanumeric characters and underscores/hyphens (you can tune this regex as needed). If invalid, throw aMetaOrderErrorwith an appropriate message. - In
getOrder(orderId: string), call this validator at the very beginning to ensureorderIdis safe and normalized before constructing the URL. Use the “cleaned” value when interpolating into the URL. - This change is localized to the order manager and does not require altering the route handlers; they will now receive a clear error if an invalid
orderIdis provided. - No external dependencies are necessary; only a regex and possibly a small helper method.
Concretely, this means:
- Add a private method, e.g.
private validateOrderId(orderId: string): string, somewhere in theMetaOrderManagerclass (e.g. nearaddAppSecretProof). - At the start of
getOrder, doconst safeOrderId = this.validateOrderId(orderId);and then usesafeOrderIdin the URL:${GRAPH_API_BASE_URL}/${safeOrderId}?${params}.
This retains all existing functionality for legitimate order IDs while preventing malformed IDs from influencing the request URL and satisfies the static analysis tool.

To fix the problem, we should prevent unsanitized user input from being logged. The problematic path is: user-controlled storeId → error message in generateStoreFeed → console.error in the route handler. The safest fix is to (a) stop embedding the raw storeId in the Error message and/or (b) sanitize the storeId before using it in any error/log message. This keeps behavior intact (we still throw an error when the store is missing) while eliminating the injection vector.
The single best minimal change is in src/lib/integrations/facebook/feed-generator.ts, where we construct the error message. We can change:
throw new Error(`Store not found: ${storeId}`);to either a constant message or a message that uses a sanitized version of storeId. A conservative approach is to remove the dynamic part entirely, since the calling code already knows which storeId it requested and does not depend on the exact message:
throw new Error('Store not found');This fully breaks the dataflow from user input into the logged message, without altering control flow or types, and without needing any new imports or helpers. No other changes are strictly necessary, since the sink (console.error('Feed generation error:', error);) can now only log messages that don’t contain user-controlled data.
Concretely:
- File:
src/lib/integrations/facebook/feed-generator.ts- Around line 425, replace
throw new Error(`Store not found: ${storeId}`);withthrow new Error('Store not found');.
- Around line 425, replace
- No additional imports, methods, or definitions are needed.
- The route file
src/app/api/integrations/facebook/feed/route.tscan remain as-is; once the error message no longer includes tainted data, the log injection issue is resolved.
