An attacker on the network path can intercept user or administrator API tokens and act against the control plane as the compromised user. The default local profile is unaffected because it uses plain HTTP. This issue is fixed in versions 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:H/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":5.5},"cvss_v3":null,"cwes":["CWE-295"],"references":["https://github.com/kumahq/kuma/commit/2d0fb382924598f8746bc85c896f50384675940f","https://github.com/kumahq/kuma/commit/85716397ffa404234bf365da0967eca0b0fa1870","https://github.com/kumahq/kuma/commit/a256af4869ae7e0ebbc2a14dc231e04ac8df1ba3","https://github.com/kumahq/kuma/commit/bb56ae628753aaec1f7846a514ab4edc35c0b569","https://github.com/kumahq/kuma/commit/d4ae0c0151596be991897651f20c5cdf32de1980"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-50166","score":0.00275,"percentile":0.19681,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v95x-xhq5-4929","url":"https://osv.dev/vulnerability/GHSA-v95x-xhq5-4929","summary":"kumactl connects to control plane without verifying TLS certificate when no CA is configured","modified":"2026-08-13T04:11:05.270163837Z","packages":[{"ecosystem":"Go","name":"github.com/kumahq/kuma/v2","purl":"pkg:golang/github.com/kumahq/kuma/v2","ranges":["<2.7.26"],"fixed":["2.7.26"]},{"ecosystem":"Go","name":"github.com/kumahq/kuma/v2","purl":"pkg:golang/github.com/kumahq/kuma/v2","ranges":[">=2.8.0 <2.9.16"],"fixed":["2.9.16"]},{"ecosystem":"Go","name":"github.com/kumahq/kuma/v2","purl":"pkg:golang/github.com/kumahq/kuma/v2","ranges":[">=2.10.0 <2.11.14"],"fixed":["2.11.14"]},{"ecosystem":"Go","name":"github.com/kumahq/kuma/v2","purl":"pkg:golang/github.com/kumahq/kuma/v2","ranges":[">=2.12.0 <2.12.11"],"fixed":["2.12.11"]},{"ecosystem":"Go","name":"github.com/kumahq/kuma/v2","purl":"pkg:golang/github.com/kumahq/kuma/v2","ranges":[">=2.13.0 <2.13.7"],"fixed":["2.13.7"]},{"ecosystem":"Go","name":"github.com/kumahq/kuma","purl":"pkg:golang/github.com/kumahq/kuma","ranges":["<=1.8.1"],"fixed":[]}]},{"id":"GO-2026-6010","url":"https://osv.dev/vulnerability/GO-2026-6010","summary":"kumactl connects to control plane without verifying TLS certificate when no CA is configured in github.com/kumahq/kuma","modified":"2026-08-13T04:11:05.270163837Z","packages":[{"ecosystem":"Go","name":"github.com/kumahq/kuma","purl":"pkg:golang/github.com/kumahq/kuma","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/kumahq/kuma/v2","purl":"pkg:golang/github.com/kumahq/kuma/v2","ranges":["<2.7.26",">=2.9.13 <2.11.14",">=2.12.4 <2.12.11",">=2.13.0 <2.13.7"],"fixed":["2.7.26","2.11.14","2.12.11","2.13.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
