Official Description

A hard-coded cryptographic key is used by Altium Enterprise Server to sign file download URLs in the Vault service. Because the key is identical across all installations, an unauthenticated network attacker who can reach the server can forge valid download signatures and retrieve files from the Vault storage area without any authentication, session, or credentials.

A separate path traversal vulnerability in the same download endpoint allows the configured storage root to be escaped, enabling reads of arbitrary files on the server filesystem. Combined, these issues allow an unauthenticated attacker to obtain sensitive server configuration and key material, which can lead to full server compromise. The vulnerability can be chained with CVE-2026-9152 to enumerate and bulk-download stored content. Altium 365 cloud deployments are not impacted in practice, as file storage uses object storage rather than the local filesystem.

Risk Analysis

This critical vulnerability in Altium Enterprise Server's Vault service uses a hard-coded cryptographic key to sign file download URLs, allowing unauthenticated attackers to forge valid signatures and retrieve arbitrary files. Combined with a path traversal flaw, this enables full server compromise and disclosure of sensitive configuration and key material. With a CVSS score of 10.0, this is an urgent and severe threat.

No public exploit is currently known for this remotely exploitable vulnerability. No authentication or credentials are required for exploitation.

Recommended Action

Apply the latest security updates for Altium Enterprise Server to address the hard-coded cryptographic key and path traversal vulnerabilities. Ensure that cryptographic keys are unique and properly managed for each installation.

Technical Analysis

CVE-2026-11414 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
