Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 at the service level.<\/p>\n<p>  Severity: 8.3 | HIGH<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-11431 Published : June 5, 2026, 10:16 p.m. | 16\u00a0minutes ago Description :A path traversal vulnerability exists in the Projects Service download endpoint shared by Altium Enterprise Server and Altium 365.
