CVE-2026-35086Network attack vector

Authenticated code execution via email template expansion

Published May 19, 2026 · Updated May 19, 2026

Code injection in Apache OFBiz email services before 24.09.06 allows remote authenticated users to execute code through crafted email content. EmailServices passes caller-controlled subject and body values to FlexibleStringExpander, causing template expressions to be evaluated instead of treated as email text. Reaching the affected email service requires authentication, and successful expansion executes attacker-supplied template logic in the OFBiz server context.
