{"id":"CVE-2025-53927","state":"PUBLISHED","title":"MaxKB sandbox bypass","description":"MaxKB is an open-source AI assistant for enterprise. Prior to version 2.0.0, the sandbox design rules can be bypassed because MaxKB only restricts the execution permissions of files in a specific directory. Therefore, an attacker can use the `shutil.copy2` method in Python to copy the command they want to execute to the executable directory. This bypasses directory restrictions and reverse shell. Version 2.0.0 fixes the issue.","publishedAt":"2025-07-17T13:50:18.268Z","updatedAt":"2025-07-17T19:56:23.111Z","severity":{"score":4.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["1Panel-dev MaxKB"],"affected":[{"vendor":"1Panel-dev","product":"MaxKB","versions":[{"version":"< 2.0.0","status":"affected"}]}],"references":["https://github.com/1Panel-dev/MaxKB/security/advisories/GHSA-5xhm-4j3v-87m4","https://github.com/1Panel-dev/MaxKB/releases/tag/v2.0.0"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:09:31.862Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/53xxx/CVE-2025-53927.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-53927","state":"PUBLISHED","datePublished":"2025-07-17T13:50:18.268Z","dateUpdated":"2025-07-17T19:56:23.111Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-07-14T17:23:35.259Z"},"containers":{"cna":{"title":"MaxKB sandbox bypass","descriptions":[{"lang":"en","value":"MaxKB is an open-source AI assistant for enterprise.
