CVE-2026-13575

HTTP::Session versions before 0.54 for Perl allow memcached command injection via unfiltered session ids in HTTP::Session::Store::CHI. The session id from the client's cookie reaches the CHI cache unchanged. The sibling HTTP::Session::Store::Memcached rejects ids that contain control characters, but the CHI store has no such check, and CHI does not escape keys for its memcached drivers. With a memcached driver, a CR and LF in the session id end the cache command early, and the server reads the bytes after them as further commands.

Check the content

Check the version numbers before you commit this entry. Some ports share an entry in the CVE database with another port, such as sqlite2 and sqlite3. The version shown here may then be one that never existed for this port.

Ranges per package from the CVE rows that match this port, in pkg notation with the port's epoch and revision, every bound checked with pkg; one range per epoch the port actually had. make newentry in security/vuxml creates the vid.

No CPE in the port Makefile

www/p5-HTTP-Session (CPE matched by the package name) has no USES=cpe. The CVE was matched through a CPE from another source, so the package and the version range may belong to a different product. Check the CVE record before using this entry.
