I have just released Slim Framework 4.15.2. This fixes a reflected XSS vulnerability in Slim’s HTML error renderer. If you are using Slim 4.4.0 to 4.15.1 and set untrusted/user-derived data into HttpException, please upgrade to Slim 4.15.2. https://www.slimframework.com/2026/05/22/slim-security-advisory.html
