Prior to version 2.10.6-lts, the ToolExecutor LD_PRELOAD sandbox hooks execve, execvpe, and execveat to prevent subprocess creation but does not hook fexecve. An authenticated attacker able to execute tool code can call fexecve to start a process outside the sandbox's intended subprocess policy. This issue is fixed in version 2.10.6-lts.","cvssScore":6.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","cwes":["CWE-693"],"vendors":[],"products":[],"references":[{"url":"https://github.com/1Panel-dev/MaxKB/commit/6fa7947a85030b87977c4026f33af11ca10dd1e6","tags":[]},{"url":"https://github.com/1Panel-dev/MaxKB/releases/tag/v2.10.6-lts","tags":[]},{"url":"https://github.com/1Panel-dev/MaxKB/security/advisories/GHSA-9mh9-v949-fwqh","tags":[]}],"exploitRefs":[{"url":"https://github.com/1Panel-dev/MaxKB/commit/6fa7947a85030b87977c4026f33af11ca10dd1e6","tags":[]},{"url":"https://github.com/1Panel-dev/MaxKB/releases/tag/v2.10.6-lts","tags":[]},{"url":"https://github.com/1Panel-dev/MaxKB/security/advisories/GHSA-9mh9-v949-fwqh","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an authenticated attacker to execute code outside the sandbox by leveraging fexecve, posing a risk to system security.","exploitability":"Exploitation requires authentication and access to tool code execution; moderate effort needed.","blast_radius":"If exploited, could lead to unauthorized process execution with potential for data compromise or system control loss.","remediation":"Update to MaxKB version 2.10.6-lts immediately to mitigate the vulnerability.","tags":["rce","auth-bypass","sandbox"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:21:44.309Z"}}
