Affected: AlmaLinux:9: perl-HTTP-Daemon

The perl-HTTP-Daemon package includes the [HTTP::Daemon](HTTP::Daemon) class, a subclass of IO::Socket::IP. Instances of the [HTTP::Daemon](HTTP::Daemon) class are HTTP/1.1 servers that listen on a socket for incoming requests.

Security Fix(es):

* perl-HTTP-Daemon: [HTTP::Daemon:](HTTP::Daemon:) Arbitrary code execution via OS command injection in send_file() (CVE-2026-8450)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Affected: Homebrew: texlive

HTTP::Daemon versions before 6.17 for Perl allow OS command injection via send_file().

send_file() opens its string argument with Perl's 2-arg open(). The 2-arg form interprets magic prefixes: '| cmd' and 'cmd |' open a pipe to a subprocess, '> path' and '>> path' open the path for write or append.

Untrusted input passed to send_file() can run OS commands at the daemon process UID. The read-pipe form ('cmd |') also leaks subprocess stdout into the HTTP response body. The write-mode forms can create or truncate files at attacker chosen paths.
