octocat/my-app/PR #42 — Add authentication flow
0 accepted·0 rejected·3 pending
1/3src/auth/validate.tsBUGlow risk
−function validateToken(token) {
− const decoded = jwt.verify(token, SECRET);
− return decoded;
−}
+function validateToken(token) {
+ const decoded = jwt.verify(token, SECRET);
+ if (decoded.exp < Date.now() / 1000) {
+ throw new TokenExpiredError();
+ }
+ return decoded;
+}
Why this change
The validateToken function was not checking for token expiration. Expired tokens would pass validation, allowing unauthorized access.
2/3src/api/handlers.tsREFACTORlow risk
−} catch (err) {
− // handle error
− res.status(500).send();
−}
+} catch (err) {
+ logger.error('Request failed', {
+ path: req.path,
+ error: err.message,
+ stack: err.stack
+ });
+ res.status(500).json({ error: 'Internal error' });
+}
Why this change
The error handler was swallowing exceptions silently. Added structured logging so failures are visible in monitoring and debugging is possible.
3/3src/utils/query.tsSECURITYhigh risk
−const result = db.query(
− `SELECT * FROM users WHERE id = '${userId}'`
−);
+const result = db.query(
+ 'SELECT * FROM users WHERE id = $1',
+ [userId]
+);
Why this change
Direct string interpolation in SQL queries creates a SQL injection vulnerability. Parameterized queries prevent malicious input from being executed as SQL.
Why Teams Switch
