CyberRota Analysis
AI-GeneratedDancer2 versions prior to 2.2.0 for Perl are vulnerable due to a flaw in the AutoPage handler that allows an attacker to bypass security checks when accessing layout files through manipulated request paths. This can lead to unauthorized disclosure of application layouts, potentially exposing sensitive information. Developers and security teams using affected versions should prioritize patching to mitigate the risk of information leakage.

Original NVD Description
Dancer2 versions before 2.2.0 for Perl serve a layout as a page when an equivalent spelling of its path misses the guard in the AutoPage handler. The handler compares the request path against the layout directory name as text, while the lookup that follows canonicalises it. A doubled slash, a dot segment, a percent-encoded slash, or a different capitalisation on a case-insensitive filesystem therefore misses the guard. The handler is off by default, enabled with auto_page. The layout wrapping every page is already public, so this discloses one of the application's other layouts.
