CVE-2026-120316 Details
Description
http4k before 6.62.0.0-ee contains a path traversal vulnerability in ThymeleafTemplates Caching and HotReload that allows unauthenticated attackers to read files outside baseTemplateDir by supplying ../ segments in ViewModel.template() values. Attackers can influence request-driven template selection so Thymeleaf's FileTemplateResolver resolves escaped paths without containment checks, disclosing any file readable by the server process.
A path traversal vulnerability has been identified in http4k versions prior to 6.62.0.0-ee, specifically within the ThymeleafTemplates Caching and HotReload features. This vulnerability allows unauthenticated attackers to read files outside the designated baseTemplateDir by injecting ../ segments into ViewModel.template() values. The issue arises because Thymeleaf's FileTemplateResolver processes these escaped paths without proper containment checks, enabling access to any file that the server process can read.
Users can upgrade to http4k version 6.62.0.0-ee or later, where this vulnerability has been addressed.
