graphite-web is vulnerable to Remote Code Execution

CVE-2013-5942GHSA-ch3j-w953-hfcm

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (graphite-web 0.9.11), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Graphite 0.9.5 through 0.9.10 uses the pickle Python module unsafely, which allows remote attackers to execute arbitrary code via a crafted serialized object, related to (1) remotestorage.py, (2) storage.py, (3) render/datalib.py, and (4) whitelist/views.py, a different vulnerability than CVE-2013-5093.

# Patch Next advisory brief: CVE-2013-5942

Advisory: graphite-web is vulnerable to Remote Code Execution
IDs: CVE-2013-5942, GHSA-ch3j-w953-hfcm
Record: https://patchnext.com/advisories/cve-2013-5942 (revision 3, source checked 26 Oct 2026, 13:17 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 10.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: graphite-web 0.9.11. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI graphite-web: affected >= 0.9.5, <= 0.9.10; fixed in 0.9.11

## Suggested inspection (read-only)
- `python -m pip show graphite-web`: 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 graphite-web.
- 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.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-ch3j-w953-hfcm (OSV record GHSA-ch3j-w953-hfcm lists affected ranges: PyPI graphite-web >=0.9.5 <0.9.11 (fixed))
- Verified: https://github.com/advisories/GHSA-ch3j-w953-hfcm (GitHub-reviewed advisory GHSA-ch3j-w953-hfcm lists affected ranges: PyPI graphite-web >=0.9.5 <=0.9.10)
