GHSA-972c-cfv8-2hq8

HIGH

GHSA-972c-cfv8-2hq8 is a high-severity (CVSS 7.5) CWE-399 vulnerability in swift. O3 Security confirms whether GHSA-972c-cfv8-2hq8 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

OpenStack Object Storage (Swift) before 2.4.0 does not properly close client connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for swift. 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 swift to 2.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-972c-cfv8-2hq8 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-972c-cfv8-2hq8 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-972c-cfv8-2hq8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
