{"cve":"CVE-2023-37266","nvd":{"published":"2023-07-17T21:15:09.733","modified":"2026-06-17T06:07:50.980","status":"Analyzed","description":"CasaOS is an open-source Personal Cloud system. Unauthenticated attackers can craft arbitrary JWTs and access features that usually require authentication and execute arbitrary commands as `root` on CasaOS instances. This problem was addressed by improving the validation of JWTs in commit `705bf1f`. This patch is part of CasaOS 0.4.4. Users should upgrade to CasaOS 0.4.4. If they can't, they should temporarily restrict access to CasaOS to untrusted users, for instance by not exposing it publicly.","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-287"],"references":["https://github.com/IceWhaleTech/CasaOS/commit/705bf1facbffd2ca40b159b0303132b6fdf657ad","https://github.com/IceWhaleTech/CasaOS/security/advisories/GHSA-m5q5-8mfw-p2hr","https://www.sonarsource.com/blog/security-vulnerabilities-in-casaos","https://github.com/IceWhaleTech/CasaOS/commit/705bf1facbffd2ca40b159b0303132b6fdf657ad","https://github.com/IceWhaleTech/CasaOS/security/advisories/GHSA-m5q5-8mfw-p2hr"],"products":["icewhale:casaos"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-37266","score":0.06844,"percentile":0.94036,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-m5q5-8mfw-p2hr","url":"https://osv.dev/vulnerability/GHSA-m5q5-8mfw-p2hr","summary":"CasaOS contains weak JWT secrets","modified":"2024-12-12T22:30:02Z","packages":[{"ecosystem":"Go","name":"github.com/IceWhaleTech/CasaOS","purl":"pkg:golang/github.com/IceWhaleTech/CasaOS","ranges":["<0.4.4"],"fixed":["0.4.4"]}]},{"id":"GO-2023-1931","url":"https://osv.dev/vulnerability/GO-2023-1931","summary":"CasaOS contains weak JWT secrets in github.com/IceWhaleTech/CasaOS","modified":"2026-03-03T04:54:00.306643Z","packages":[{"ecosystem":"Go","name":"github.com/IceWhaleTech/CasaOS","purl":"pkg:golang/github.com/IceWhaleTech/CasaOS","ranges":["<0.4.4"],"fixed":["0.4.4"]}]}],"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).
