         CVE ID:  CVE-2026-114627

   Distribution:  Web-Simple
       Versions:  before 0.036
       MetaCPAN:  https://metacpan.org/dist/Web-Simple
       VCS Repo:  https://github.com/p5sagit/Web-Simple

Web::Simple versions before 0.036 for Perl do not escape values
interpolated into double-quoted strings in HTML::Tags output

Description
-----------
Web::Simple versions before 0.036 for Perl do not escape values
interpolated into double-quoted strings in HTML::Tags output.

Under use HTML::Tags or use XML::Tags, a double-quoted string literal
becomes a StringThing object that holds each interpolated value as a
separate part. The escaping step passes such objects through, and
stringify joins their interpolated parts as is. A value passed on its
own, as in <p>, $value, </p>, is entity-escaped, but the same value in
"Hello $value" is not.

An attacker who controls a value that an application interpolates into
a double-quoted string can inject script into the generated page.

Problem types
-------------
- CWE-79 Improper Neutralization of Input During Web Page Generation
   ('Cross-site Scripting')

Solutions
---------
Upgrade to Web-Simple 0.036 or later.
