CVE-2025-23026

Summary

CVE-2025-23026 is a newly disclosed vulnerability affecting the Java Template Engine (jte) versions 3.1.15 and below. The issue lies in the engine's handling of `script` tags and attributes in HTML templates that contain Javascript template strings (using backticks). jte's `Escape` class fails to properly escape backticks, leading to Cross-Site Scripting (XSS) attacks. This vulnerability can be exploited by injecting malicious scripts into the templates rendered by jte's `OwaspHtmlTemplateOutput`. Users are strongly advised to upgrade to version 3.1.16 or later to mitigate the risk, as there are currently no known workarounds for this vulnerability.
