Saiadmin
Monthly
Unrestricted file upload via shell_exec in SaiAdmin up to version 5.0.1 exposes the Plugin Upload Endpoint (/app/saipackage/install/upload) to potential remote code execution by authenticated high-privilege users. The affected function passes uploaded plugin content through shell_exec without adequate file-type validation, a pattern consistent with CWE-434 that typically enables server-side code execution beyond simple file storage. A proof-of-concept exploit has been publicly disclosed on GitHub (CVE-2026-19383 issue), raising the operational risk above what the conservative VulDB-assigned CVSS 4.0 score of 5.1 might suggest; no vendor patch has been identified at time of analysis.
