CVE-2022-24894

Symfony is a PHP framework for web and console applications and a set of
reusable PHP components. The Symfony HTTP cache system, acts as a reverse
proxy: It caches entire responses (including headers) and returns them to
the clients. In a recent change in the AbstractSessionListener, the
response might contain a Set-Cookie header. If the Symfony HTTP cache
system is enabled, this response might bill stored and return to the next
clients. An attacker can use this vulnerability to retrieve the victim’s
session. This issue has been patched and is available for branch 4.4.
