Description

Impact

The existing URI path filters in OctoRPKI (version < 1.4.3) mitigating Path traversal vulnerability could be bypassed by an attacker. In case a malicious TAL file is parsed, it was possible to write files outside the base cache folder.

Specific Go Packages Affected

github.com/cloudflare/cfrpki/cmd/octorpki

Patches

The issue was fixed in version 1.4.3

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/cloudflare/cfrpki. 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 github.com/cloudflare/cfrpki to 1.4.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3jhm-87m6-x959 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-3jhm-87m6-x959 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-3jhm-87m6-x959. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
