• CVE-2026-61667: 1.21% estimated exploitation activity in the next 30 days; percentile 68.56 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The FileCatalog DatasetManager runs a query on the database and passes the result to eval. The SQL query contains an injection vulnerability which allows an authenticated user to control the parameter returned to the eval resulting in remote code execution. Details The FileCatalog checkDataset function passes its datasets argument directly to the backend DB handler: https://github.com/DIRACGrid/DIRAC/blob/f7e0a3ac153315030fb3520e8ca747f013758967/src/DIRAC/DataManagementSystem/Service/FileCatalogHandler.py#L591-L593 Which in turn passes it to the checkDataset function: https://github.com/DIRACGrid/DIRAC/blob/f7e0a3ac153315030fb3520e8ca747f013758967/src/DIRAC/DataManagementSystem/DB/FileCatalogComponents/DatasetManager/DatasetManager.py#L390 This uses an f-string to create a query without escaping, resulting in an SQL injection:…

# Patch Next advisory brief: CVE-2026-61667

Advisory: DIRAC is vulnerable to RCE in FileCatalog DatasetManager via SQL injection + eval
IDs: CVE-2026-61667, GHSA-m4m7-4cw8-62j6
Record: https://patchnext.com/advisories/cve-2026-61667 (revision 3, source checked 26 Oct 2026, 13:46 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: dirac 9.1.10, 9.0.22, 8.0.79. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI dirac: affected >= 6, < 8.0.79; >= 8.1.0a1, < 9.0.22; >= 9.1.0, < 9.1.10; fixed in 9.1.10, 8.0.79, 9.0.22

## Suggested inspection (read-only)
- `python -m pip show dirac`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on dirac.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
