CVE ID :CVE-2026-35391 Published : April 6, 2026, 9:16 p.m. | 14 minutes ago Description :Bulwark Webmail is a self-hosted webmail client for Stalwart Mail Server. Prior to 1.4.11, the getClientIP() function in lib/admin/session.ts trusted the first (leftmost) entry of the X-Forwarded-For header, which is fully controlled by the client.

This vulnerability is fixed in 1.4.11. Severity: 8.7 | HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...
