LOWFix: helm/helm#8317

GHSA-qq3j-xp49-j73f is a low-severity (CVSS 3.7) Path Traversal vulnerability in helm.sh/helm/v3. O3 Security confirms whether GHSA-qq3j-xp49-j73f is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

The Helm core maintainers have identified an information disclosure vulnerability in Helm 3.0.0-3.2.3.

Impact

A traversal attack is possible when installing Helm plugins from a tar archive over HTTP. It is possible for a malicious plugin author to inject a relative path into a plugin archive, and copy a file outside of the intended directory.

Traversal Attacks are a form of a Directory Traversal that can be exploited by extracting files from an archive. The premise of the Directory Traversal vulnerability is that an attacker can gain access to parts of the file system outside of the target folder in which they should reside. The attacker can then overwrite executable files and either invoke them remotely or wait for the system or user to call them, thus achieving Remote Command Execution on the victim's machine. The vulnerability can also cause damage by overwriting configuration files or other sensitive resources, and can be exploited on both client (user) machines and servers.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for helm.sh/helm/v3. 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 helm.sh/helm/v3 to 3.2.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qq3j-xp49-j73f 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-qq3j-xp49-j73f 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-qq3j-xp49-j73f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
