CVE-2026-35490
CRITICAL9.8EPSS 0.03%changedetection.io Vulnerable to Authentication Bypass via Decorator Ordering
發布日:2026/4/6修改日:2026/5/20
描述
changedetection.io is a free open source web page change detection tool. Prior to 0.54.8, the @login_optionally_required decorator is placed before (outer to) @blueprint.route() instead of after it. In Flask, @route() must be the outermost decorator because it registers the function it receives. When the order is reversed, @route() registers the original undecorated function, and the auth wrapper is never in the call chain. This silently disables authentication on these routes. This vulnerability is fixed in 0.54.8.
