Forwarded: https://github.com/Perl-Toolchain-Gang/HTTP-Tiny/commit/d73c7651e82ace02693842df55928b6c3ae7c38d
Control: found -1 5.32.1-4
Control: found -1 5.36.0-1
Control: found -1 5.42.2-1

The following vulnerability was published[0] for HTTP-Tiny:

  CVE ID:  CVE-2026-7010
  Distribution:  HTTP-Tiny
  Versions:  before 0.093

  MetaCPAN:  https://metacpan.org/dist/HTTP-Tiny
  VCS Repo:  https://github.com/Perl-Toolchain-Gang/HTTP-Tiny

  HTTP::Tiny versions before 0.093 for Perl do not validate CRLF in HTTP
  request lines or control field header values.

  The unvalidated inputs are the method and URI in the request line, the
  URL host that becomes the `Host:` header, and HTTP/1.1 control data
  field values.

  An attacker who controls one of these inputs, for example a user
  supplied URL passed to a webhook or URL fetch endpoint, can inject
  additional headers and smuggle requests to the upstream server.

This CPAN module is shipped in both libhttp-tiny-perl and perl. The
libhttp-tiny-perl package was already fixed for sid + forky in version
0.092-2. The issue is marked as no-dsa in the security tracker [1].

Copying the libhttp-tiny-perl maintainers, and Salvatore for his security
hat. I suppose we can manage without a separate libhttp-tiny-perl bug
at this point, but feel free to clone one if it helps.
