CVE-2026-78188 WebDyne versions from 2.014 before 3.022 for Perl issue session cookies without the Secure, HttpOnly and SameSite attributes
CVE-2026-78189 WebDyne versions from 3.007 before 3.022 for Perl execute .psp files outside the document root via path traversal in the PSGI API route fallback CVE-2026-78190 WebDyne versions from 2.014 before 3.022 for Perl reflect request parameters unescaped into form field values, allowing cross-site scripting CVE-2026-78191 WebDyne versions from 2.031 before 3.022 for Perl execute files with .psp anywhere in the name as Perl pages 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 ======================================================================== CVE-2026-78188 CPAN Security Group ======================================================================== CVE ID: CVE-2026-78188 Distribution: WebDyne Versions: from 2.014 before 3.022 MetaCPAN: https://metacpan.org/dist/WebDyne VCS Repo: https://github.com/aspeer/WebDyne WebDyne versions from 2.014 before 3.022 for Perl issue session cookies without the Secure, HttpOnly and SameSite attributes Description ----------- WebDyne versions from 2.014 before 3.022 for Perl issue session cookies without the Secure, HttpOnly and SameSite attributes. WebDyne::Session sets its session cookie with only a name, value and path. Browsers then send the session ID over plain HTTP and with cross-site requests, and expose it to page scripts. A network attacker or an injected script can steal the session, and another site can make requests that carry it. Problem types ------------- - CWE-614 Sensitive Cookie in HTTPS Session Without 'Secure' Attribute - CWE-1004 Sensitive Cookie Without 'HttpOnly' Flag - CWE-1275 Sensitive Cookie with Improper SameSite Attribute Solutions --------- Upgrade to WebDyne 3.022 or later. The SameSite attribute also requires CGI::Simple 1.22 or later.

When a request matches no file, the PSGI handler retries it as an API route through api_filename. That keeps .. segments in the request path and only checks that the joined path starts with the document root, which a request for /../private passes. A remote attacker can run the embedded Perl in any .psp file the server can read, such as one uploaded to a directory outside the document root. Problem types ------------- - CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') Solutions --------- Upgrade to WebDyne 3.022 or later.

The textfield, password_field and filefield tags fill their value attribute from the request parameter of the same name. WEBDYNE_CGI_AUTOESCAPE, which controls escaping of these values, defaults to off. From 2.022, WebDyne::HTML::Tiny also replaced its entity_encode method with one that returns its input unchanged, so enabling WEBDYNE_CGI_AUTOESCAPE has no effect. A remote attacker can inject script into any page using these tags through a crafted link. Problem types ------------- - CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Solutions --------- Upgrade to WebDyne 3.022 or later.

WebDyne decides whether to run a requested file as a page by matching its name against WEBDYNE_PSP_EXT_RE, which has no end anchor. An application that accepts uploads by checking only the final extension lets a remote attacker upload a file such as report.psp.pdf and run its embedded Perl by requesting it. Problem types ------------- - CWE-777 Regular Expression without Anchors Solutions --------- Upgrade to WebDyne 3.022 or later.

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. Problem types ------------- - CWE-540 Inclusion of Sensitive Information in Source Code - CWE-1188 Initialization of a Resource with an Insecure Default Solutions --------- Upgrade to WebDyne 3.022 or later.
