Prior to 1.18.6, a process inside a sandbox could send MSGID_FILE_SET_ATTRIBUTES or MSGID_FILE_SET_SHORT_NAME to SbieSvc and cause the SYSTEM service to open and modify an existing file outside the sandbox. The direct primitive changes file attributes, timestamps, writeability, or 8.3 short names; a short-name redirection can additionally contribute to SYSTEM code execution when a privileged process resolves an attacker-controlled short-name path in a location SbieSvc can open. This vulnerability is fixed in 1.18.6.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.9,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"}],"modifiedAt":1793829287970,"publishedAt":1793829287970,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/sandboxie-plus/Sandboxie/security/advisories/GHSA-vhjw-4xvf-c74w"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/sandboxie-plus/Sandboxie/commit/4e121cc4dacdc31973adcb81581b0414d48c26fc"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/sandboxie-plus/Sandboxie/releases/tag/v1.18.6"}],"remediation":[],"revision":"aa5edba764864f03e3dae599f428d10f8fda70e0bf0987f665043d26e90befba","sources":[{"modifiedAt":1793829287970,"name":"CNA: GitHub_M","retrievedAt":1793830265853,"url":"https://www.cve.org/CVERecord?id=CVE-2026-102280"}],"ssvc":null,"status":"published","title":"Sandboxie-Plus: Sandbox containment bypass","updatedAt":1793830265853}
