CVE-2025-68115Network attack vector

Reflected XSS via unescaped Mustache variables

Published Dec 16, 2025 · Updated Dec 16, 2025

Reflected XSS in Parse Server before 8.6.1 and 9.0.0 through 9.1.0-alpha.2 allows remote attackers to run script in a user's browser. Password-reset and email-verification templates use unescaped Mustache triple braces for URL, application, username, token, and locale values placed in form attributes. Exploitation requires a user to load a crafted page; the injected script executes in the page origin and can read or modify browser-accessible data.
