CVE-2017-9790GHSA-vpcv-78cp-whr3

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.apache.mesos:mesos 1.3.1, 1.2.2, 1.1.3), 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.

  • CVE-2017-9790: 2.45% estimated exploitation activity in the next 30 days; percentile 84.36 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.
Source description

As published by the source; long descriptions are shortened.

When handling a libprocess message wrapped in an HTTP request, libprocess in Apache Mesos before 1.1.3, 1.2.x before 1.2.2, 1.3.x before 1.3.1, and 1.4.0-dev crashes if the request path is empty, because the parser assumes the request path always starts with '/'. A malicious actor can therefore cause a denial of service of Mesos masters rendering the Mesos-controlled cluster inoperable.

# Patch Next advisory brief: CVE-2017-9790

Advisory: Use after free in Apache Mesos
IDs: CVE-2017-9790, GHSA-vpcv-78cp-whr3
Record: https://patchnext.com/advisories/cve-2017-9790 (revision 1, source checked 26 Oct 2026, 16:02 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.mesos:mesos 1.3.1, 1.2.2, 1.1.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.mesos:mesos: affected < 1.1.3; >= 1.2.0, < 1.2.2; >= 1.3.0, < 1.3.1; fixed in 1.2.2, 1.3.1, 1.1.3

## Suggested inspection (read-only)
- Maven org.apache.mesos:mesos: check the installed version with your package manager.

## 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 org.apache.mesos:mesos.
- 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://github.com/advisories/GHSA-vpcv-78cp-whr3 (GitHub-reviewed advisory GHSA-vpcv-78cp-whr3 lists affected ranges: Maven org.apache.mesos:mesos >=0 =1.2.0 =1.3.0 <1.3.1)

Commands are suggestions: review each one before running it.
