1-Click Fix Prompt for Cursor & Claude Code
Review my codebase for "Session Token Expiry and Revocation Handlers Present" (AUTH-008). Issue: Agents generate JWT tokens with infinite or multi-year expiry times so users never have to re-login. Remediation required: Set access token lifespan to under 2 hours and implement token refresh and user logout invalidation. Please: 1. Locate any occurrences of this issue across my repository. 2. Refactor the code to follow production standards without breaking existing functionality. 3. Provide a clear command or step to test and verify the fix.
Why AI Assistants Write This Bug
Agents generate JWT tokens with infinite or multi-year expiry times so users never have to re-login.
AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.
Code Comparison
Common AI Code PatternVulnerable
// Vulnerable AI-generated pattern for: Session Token Expiry and Revocation Handlers Present
// Insecure route handler trusting body user ID (IDOR risk)
export async function POST(req: Request) {
const { userId, newEmail } = await req.json();
// BUG: Any user can modify any other user record!
await db.user.update({ where: { id: userId }, data: { email: newEmail } });
return Response.json({ success: true });
}Launch-Ready Fix
// Production-ready fix for: Session Token Expiry and Revocation Handlers Present
// Protected route deriving identity from verified session
export async function POST(req: Request) {
const session = await auth();
if (!session?.user?.id) {
return Response.json({ error: "Unauthorized" }, { status: 401 });
}
const { newEmail } = await req.json();
// Scoped strictly to authenticated session user ID
await db.user.update({ where: { id: session.user.id }, data: { email: newEmail } });
return Response.json({ success: true });
