CVE-2026-61667
CriticalCVSS 9.9Exploitation Probability (EPSS)
Elevated risk67th percentile - higher than 67% of all known CVEs
Summary
In DIRAC prior to versions 8.0.79, 9.0.22, and 9.1.10, the checkDataset function in FileCatalogHandler.py forwards an authenticated caller-controlled datasets value to __checkDataset in DatasetManager.py, 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.
Risk Assessment
An authenticated attacker can execute commands as the account running DIRAC services, exposing dirac.cfg, database passwords, stored proxies, and tokens, fully compromising the DIRAC system and allowing alteration of local log evidence.
Recommendation
Upgrade DIRAC to version 8.0.79, 9.0.22, or 9.1.10 (or later). Consider rotating credentials (database passwords, tokens, proxies) if exploitation is suspected.
Other vulnerabilities in DIRAC
See all- CVE-2026-45579Critical
In DIRAC prior to versions 8.0.79, 9.0.22, and 9.1.10, the export_getRequestCountersWeb function in ReqManagerHandler.py passes an authenticated caller-controlled groupingAttribute to getRequestCountersWeb in RequestDB.py. An unrecognized value is resolved against the Request object and evaluated as Python code, allowing a crafted dunder attribute expression to reach operating-system functions and execute commands.
- CVE-2026-61668High
DIRAC's PilotWrapper.py downloads the second-stage pilot.tar archive and its reference checksum without TLS certificate verification, using ssl._create_unverified_context. An attacker able to redirect or intercept network traffic (e.g., via DNS or routing manipulation) can substitute both the pilot code and its checksum, leading to arbitrary code execution with access to pilot proxy credentials. Fixed in versions 8.0.79, 9.0.22, and 9.1.10.
Original NVD description (English source)
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.
