How to Fix CVE-2026-26057

To remediate this vulnerability, upgrade all affected Cisco ai skill scanner dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

cisco-ai-skill-scanner fixed: 1.0.2 
pip install cisco-ai-skill-scanner>=1.0.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show cisco-ai-skill-scanner

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-26057, inspect your installed packages using pip:

pip show cisco-ai-skill-scanner

Analyze the terminal output to locate any version of Cisco ai skill scanner in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.2), your application is affected.

Note: The pip show cisco-ai-skill-scanner command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. In Cisco ai skill scanner, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

**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. **For more information:** If you have any questions or comments about this advisory: - [Open an issue in cisco-ai-defense/skill-scanner](https://github.com/cisco-ai-defense/skill-scanner/issues) - Email Cisco Open Source Security ([oss-security@cisco.com](mailto:oss-security@cisco.com)) and Cisco PSIRT ([psirt@cisco.com](mailto:psirt@cisco.com)) **Credits:** - Research: Richard Tweed (@RichardoC) - Fix ideation and implementation: Richard Tweed (@RichardoC) - Release engineering: Vineeth Sai Narajala (@vineethsai7)
