The JWT validation doesn't check the expiration claim.\n\n**Solution:** Add exp claim validation to the JWT handler\n\n```go\nfunc ValidateToken(token string) bool {\n claims, err := parseToken(token)\n if err != nil {\n return false\n }\n // Add expiration check\n if claims.ExpiresAt.Before(time.Now()) {\n return false\n }\n return true\n}\n```\n\n**Learning:** Always validate JWT expiration claims explicitly. Don't assume the parsing library does it automatically."}}

Instead, cache only the token validation result (valid/invalid) with the token hash as key.\n\n**Reference:** See OWASP Authentication Cheat Sheet: https://cheatsheetseries.owasp.org/cheatsheets/Authentication_Cheat_Sheet.html"}}
