Description

Impact

A vulnerability in Ghost’s media inliner mechanism allows staff users in possession of a valid authentication token for the Ghost Admin API to exfiltrate data from internal systems via SSRF.

Vulnerable versions

This vulnerability is present in Ghost v5.38.0 to v5.130.5 to and Ghost v6.0.0 to v6.10.3.

Patches

v5.130.6 and v6.11.0 contain a fix for this issue.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ghost. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update ghost to 6.11.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vmc4-9828-r48r is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-vmc4-9828-r48r is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-vmc4-9828-r48r. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
