CVE ID :CVE-2026-9102
Published : May 20, 2026, 8:16 p.m. | 42 minutes ago
Description :A path traversal vulnerability exists in the Altium Enterprise Server ComparisonService due to missing filename sanitization in the Gerber file upload APIs. A regular authenticated workspace user can supply a crafted filename in the multipart Content-Disposition header to escape the intended temporary upload directory and write arbitrary files to any location on the server filesystem. Because content-controlled files can be written to web-accessible directories, this can be escalated to remote code execution in the context of the service account. It can also be used to overwrite application binaries or configuration files, leading to service takeover or denial of service.
Severity: 9.4 | CRITICAL
