CVE-2026-11419
CWE-22Published: June 5, 2026· Updated: Jun 5, 2026
Official Description
A path traversal vulnerability exists in the Altium Enterprise Server Vault Service UploadController due to improper validation of a user-controlled path component in image upload requests. An authenticated user can supply a crafted absolute path so that the configured storage root is discarded, allowing arbitrary files to be written to any location on the server filesystem writable by the service account.
Because content-controlled files can be written to web-accessible directories, or used to overwrite application binaries or configuration files, this can be escalated to remote code execution, service takeover, or denial of service. Altium 365 cloud deployments are not affected, as the affected endpoint is not reachable and the cloud storage architecture mitigates the file-write primitive.
Risk Analysis
This critical path traversal vulnerability in Altium Enterprise Server's Vault Service UploadController allows an authenticated user to write arbitrary files to any location on the server filesystem. By supplying a crafted absolute path in image upload requests, an attacker can achieve remote code execution, service takeover, or denial of service. With a CVSS score of 9.4, this is a high-severity vulnerability.
No public exploit is currently known for this remotely exploitable vulnerability. Exploitation requires prior authentication.
Apply the latest security updates for Altium Enterprise Server to address this path traversal vulnerability. Implement strict input validation for file upload paths and ensure proper access controls are in place.
Technical Analysis
CVE-2026-11419 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
