• CVE-2026-45579: 0.86% estimated exploitation activity in the next 30 days; percentile 58.69 (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 An remote code execution vulnerability exists in RequestManager due to the use of eval on untrusted input that allows any authenticated user to run code/commands on the DIRAC server as the system user running the DIRAC services. Details The exportgetRequestCountersWeb function is callable by any authenticated user and just passes its parameters directly to the database instance: https://github.com/DIRACGrid/DIRAC/blob/f7e0a3ac153315030fb3520e8ca747f013758967/src/DIRAC/RequestManagementSystem/Service/ReqManagerHandler.py#L270 If the groupingAttribute string is unrecognised, Request. is prepended to it and the result is passed into an eval() call: https://github.com/DIRACGrid/DIRAC/blob/f7e0a3ac153315030fb3520e8ca747f013758967/src/DIRAC/RequestManagementSystem/DB/RequestDB.py#L766-L776 By passing in a dunder string that is applicable to the Request object, it's possible to work back up to functions in the os module and trigger them to be called in the server context. There are…

# Patch Next advisory brief: CVE-2026-45579

Advisory: DIRAC is vulnerable to RCE in RequestManager due to eval on untrusted input
IDs: CVE-2026-45579, GHSA-9jpv-c7p4-997x
Record: https://patchnext.com/advisories/cve-2026-45579 (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.
