CVE-2026-93711

Dancer2 versions before 2.2.0 for Perl are vulnerable to CRLF injection because the headers_to_array routine fails to strip CR and LF characters from response header names, though it does strip them from values. Because the name remains intact, it reaches the PSGI server and, if not validated, is...

CVE-2026-93711 Dancer2 versions before 2.2.0 for Perl do not strip CR and LF from response header names in headers_to_array

Dancer2 versions before 2.2.0 for Perl do not strip CR and LF from response header names in headerstoarray. The routine removes CR and LF from each header value but not from the name. A name carrying them therefore reaches the PSGI server intact. A server that does not validate keys writes it to...

CVE-2026-93710

Dancer2 versions 2.0.0 through 2.1.x for Perl are vulnerable to an improper cleanup issue during exception handling in compile_hooks. When a hook dies and fires core.app.hook_exception, the system initiates a cleanup process. If the exception handler halts the response without stopping this clean...

CVE-2026-93709 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

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...

CVE-2026-93709

Dancer2 versions before 2.2.0 for Perl are vulnerable to a path traversal-like issue in the AutoPage handler. The vulnerability exists because the handler compares the request path against the layout directory name as plain text, but the subsequent lookup canonicalizes the path. Attackers can use...
