CVE-2026-40478

CVE-2026-40478 affects the Thymeleaf Java template engine (versions up to 3.1.3.RELEASE). A security bypass allows unauthenticated SSTI by passing unvalidated input to the expression evaluation mechanism; this is fixed in 3.1.4.RELEASE. Connected sources consistently state the root cause as impro...
