CVE-2026-26057

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.

CVE-2026-26057 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.0.2); upgrading removes the vulnerable code path.

1. What is CVE-2026-26057? CVE-2026-26057 is a medium-severity security vulnerability in cisco-ai-skill-scanner (pip), affecting versions < 1.0.2. It is fixed in 1.0.2.
2. How severe is CVE-2026-26057? CVE-2026-26057 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of cisco-ai-skill-scanner are affected by CVE-2026-26057? cisco-ai-skill-scanner (pip) versions < 1.0.2 is affected.
4. Is there a fix for CVE-2026-26057? Yes. CVE-2026-26057 is fixed in 1.0.2. Upgrade to this version or later.
5. Is CVE-2026-26057 exploitable, and should I be worried? Whether CVE-2026-26057 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-26057 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-26057? Upgrade cisco-ai-skill-scanner to 1.0.2 or later.
