graphite-web is vulnerable to Remote Code Execution via renderLocalView function

CVE-2013-5093GHSA-m923-w2gj-v43g

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.

The renderLocalView function in render/views.py in graphite-web in 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.

# Patch Next advisory brief: CVE-2013-5093

Advisory: graphite-web is vulnerable to Remote Code Execution via renderLocalView function
IDs: CVE-2013-5093, GHSA-m923-w2gj-v43g
Record: https://patchnext.com/advisories/cve-2013-5093 (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 9.5)
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
