{"id":"CVE-2025-53927","summary":"MaxKB sandbox bypass","details":"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.","aliases":["GHSA-5xhm-4j3v-87m4"],"modified":"2026-04-10T05:31:01.002652Z","published":"2025-07-17T13:50:18.268Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/53xxx/CVE-2025-53927.json","cwe_ids":["CWE-94"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/1Panel-dev/MaxKB/releases/tag/v2.0.0"},{"type":"ADVISORY","url":"https://github.com/1Panel-dev/MaxKB/security/advisories/GHSA-5xhm-4j3v-87m4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/53xxx/CVE-2025-53927.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-53927"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/1panel-dev/maxkb","events":[{"introduced":"0"},{"fixed":"c96de7a5f536909aef37fae92f97f62798eb1373"}]}],"versions":["v0.9.0","v0.9.1","v1.0.0","v1.0.1","v1.1.0","v1.1.1","v1.1.2","v1.1.3","v1.10.0-lts","v1.10.1-lts","v1.10.2-lts","v1.10.3-lts","v1.10.4-lts","v1.2.0","v1.2.1","v1.3.0","v1.4.0","v1.5.0","v1.6.0","v1.6.1","v1.7.0","v1.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-53927.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L"}]}
