In versions of Sealos prior to 4.2.1-rc4 an improper configuration of role based access control (RBAC) permissions resulted in an attacker being able to obtain cluster control permissions, which could control the entire cluster deployed with Sealos, as well as hundreds of pods and other resources within the cluster. This issue has been addressed in version 4.2.1-rc4. Users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-863","CWE-287"],"references":["https://github.com/labring/sealos/commit/4cdf52e55666864e5f90ed502e9fc13e18985b7b","https://github.com/labring/sealos/security/advisories/GHSA-74j8-w7f9-pp62","https://github.com/labring/sealos/commit/4cdf52e55666864e5f90ed502e9fc13e18985b7b","https://github.com/labring/sealos/security/advisories/GHSA-74j8-w7f9-pp62"],"products":["sealos_project:sealos"],"source":"nvd","synced_at":"2026-10-19T21:38:30.124994567+00:00"},"epss":{"cve":"CVE-2023-33190","score":0.00712,"percentile":0.53622,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-74j8-w7f9-pp62","url":"https://osv.dev/vulnerability/GHSA-74j8-w7f9-pp62","summary":"Improper configuration of RBAC permissions obtaining cluster control permissions","modified":"2023-11-08T04:12:39.629571Z","packages":[{"ecosystem":"Go","name":"github.com/labring/sealos","purl":"pkg:golang/github.com/labring/sealos","ranges":["<4.2.1-rc4"],"fixed":["4.2.1-rc4"]}]}],"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).
