CVE-2026-61667

Unauthenticated RCE via unsanitized datasetName in SQL → eval in DIRAC

• CVSS 9.9
• 89
• Input Validation and Sanitization
• Remote

DIRAC is an interware, meaning a software framework for distributed computing. Prior to versions 8.0.79, 9.0.22, and 9.1.10, DataManagementSystem/Service/FileCatalogHandler.py checkDataset forwards an authenticated caller-controlled datasets value to DatasetManager.py __checkDataset, where datasetName is interpolated into an FC_MetaDatasets SQL query without parameterization. The injected query can control the returned MetaQuery value, which is passed to Python eval and permits command execution as the account running the DIRAC services. Successful exploitation can expose dirac.cfg, database passwords, stored proxies, and tokens, fully compromise the DIRAC system, and allow alteration of local log evidence. This issue is fixed in versions 8.0.79, 9.0.22, and 9.1.10.
