CVE-2026-85134Network attack vector

Authenticated code execution via dangerous file upload

Published Sep 28, 2026 · Updated Sep 28, 2026

Unrestricted file upload in Bimser eBA Plus from 6.7.141 to before 10.0.11 allows remote authenticated users to place a web shell on the server. The published record identifies the dangerous-file upload failure but does not disclose the upload handler or how file-type controls fail. Exploitation requires an account with upload access; an uploaded web shell provides a route to server-side command execution.
