Prevents hanging requests + +3. **Error Message Sanitization** + - Removed user input from error messages + - Generic error messages for users + - Improved error logging + +4. **Type Safety Improved** + - Created `UpdateAIApiKeyDTO` for type safety + - Replaced `Map` with DTO + +5. **Input Validation Enhanced** + - Added null/empty checks in prompt building + - Added length validation in prompt building + - Added bounds checking for cursor line number + +### ⚠️ Remaining Issues (Require Additional Work) + +1. **Rate Limiting** - Not implemented (requires infrastructure) + - **Impact:** High - Could allow cost abuse + - **Recommendation:** Implement using Spring's rate limiting or Redis-based solution + - **Workaround:** Monitor API usage and add alerts + +2. **Explicit Authorization** - Relies on Spring Security defaults + - **Impact:** Medium - Low risk if Spring Security properly configured + - **Recommendation:** Add `@PreAuthorize("hasAuthority('USER')")` annotations + - **Current Protection:** `getForCurrentUser()` ensures user isolation + +3. **API Key Format Validation** - Only length checked, not format + - **Impact:** Low - Poor UX but not a security issue + - **Recommendation:** Add format validation (e.g., Claude keys start with "sk-ant-") + - **Current Protection:** Length limit prevents extremely long invalid keys + +4. **Prompt Injection Protection** - Basic validation only + - **Impact:** Low-Medium - User controls their own API key + - **Recommendation:** Add prompt injection detection patterns + - **Current Protection:** Input size limits and basic sanitization + - **Note:** Since users provide their own API keys, this is expected behavior + +5. **AI Response Code Injection** - AI-generated code inserted directly + - **Impact:** Low - Code goes to editor, not executed automatically + - **Recommendation:** User must review code before applying (current behavior) + - **Current Protection:** User must explicitly click "Apply" button + - **Note:** This is expected behavior for code generation feature + +6. **XSS in Response Display** -
