CVE-2026-26057 is a critical vulnerability in Cisco Skill Scanner versions 1.0.1 and earlier, allowing unauthenticated remote attackers to interact with the API server if enabled. This vulnerability, caused by erroneous binding to multiple interfaces, enables attackers to trigger a denial of service (DoS) by consuming excessive resources or upload arbitrary files. With a CVSS score of 9.1 (CRITICAL), it requires no user interaction and has high impact on integrity and availability. While no public exploits (Metasploit, Nuclei, ExploitDB) are currently available and it is not on the KEV catalog, its low EPSS score and lack of community discussion suggest it is not actively exploited or widely known.
