CVE-2026-24127 describes a reflected Cross-Site Scripting (XSS) vulnerability in Typemill, a flat-file CMS, affecting versions 2.19.1 and below. This flaw allows an attacker to inject and execute malicious scripts in the login page context when authentication fails, due to improper encoding of the username value in the login error view template. Rated as Medium severity (CVSS 6.1), it requires user interaction (UI:R) but can be exploited remotely (AV:N) with low attack complexity (AC:L), potentially leading to limited confidentiality and integrity impacts. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV listing, though it has garnered significant community discussion.
