MEDIUMSkill-scanner Unsecured Network Binding Vulnerability
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Description: A vulnerability in the API Server of Skill Scanner could allow a unauthenticated, remote attacker to interact with the server API and either trigger a denial of service (DoS) condition or upload arbitrary files.
This vulnerability is due to an erroneous binding to multiple interfaces. An attacker could exploit this vulnerability by sending API requests to a device exposing the affected API Server. A successful exploit could allow the attacker to consume an excessive amount of resources (memory starvation) or to upload files to arbitrary folders on the affected device.
Conditions: This vulnerability affects Skill-scanner 1.0.1 and earlier releases when the API Server is enabled. The API Server is not enabled by default.
Fixed Software: Skill-scanner software releases 1.0.2 and later contained the fix for this vulnerability.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cisco-ai-skill-scanner. 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.
Fix
Update cisco-ai-skill-scanner to 1.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ppfx-73j5-fhxc is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-ppfx-73j5-fhxc 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-ppfx-73j5-fhxc. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-ppfx-73j5-fhxc in your dependencies?
O3 detects GHSA-ppfx-73j5-fhxc across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
