There are 3 open security issues in trixie.
3 issues left for the package maintainer to handle:
- CVE-2026-114627:
(needs triaging)
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 $value" is not. An attacker who controls a value that an application interpolates into a double-quoted string can inject script into the generated page.
- CVE-2026-114629:
(needs triaging)
Web::Simple versions before 0.035 for Perl allocate a buffer sized by the Content-Length header for urlencoded body parameters. Web::Dispatch::ParamParser::get_unpacked_body_from reads an application/x-www-form-urlencoded body using a single read call, with no cap and the return value ignored. Perl's read grows the buffer to the requested length before reading, so the declared Content-Length determines the allocation. An attacker can trigger this through any route whose dispatch specification has a % body-parameter match, such as sub (POST + %name=), sending a Content-Length far larger than the body actually sent. No authentication is involved.
- CVE-2026-120212:
(needs triaging)
Web::Simple versions before 0.037 for Perl do not escape single quotes in HTML::Tags output. HTML::Tags and XML::Tags escape a plain string value by replacing only &, ", < and > with entities. A value interpolated into a single-quoted attribute, as in <a href='$value'>, can therefore close the attribute and add new ones, such as an event handler. Double-quoted attributes are not affected. An attacker who controls a value that an application interpolates into a single-quoted attribute can inject script into the generated page.
