CVE-2026-78192: WebDyne versions from 2.022 before 3.022 for Perl disclose application source to unauthenticated clients via the viewer in the default index page
Published Oct 31, 2026
·Updated
WebDyne versions from 2.022 before 3.022 for Perl disclose application source to unauthenticated clients via the viewer in the default index page.
WebDyne's wrapper scripts, such as webdyne.psgi, enable the built-in index page by default. Its source viewer returns files under the document root named in the source parameter of an HTMX request, including .psp, .pm and .pl files.
A remote attacker can read the application's Perl code, including the PERL blocks of .psp pages and any credentials they hold.
