What is CVE-2022-24894?
CVE-2022-24894 is a medium-severity vulnerability in Sensiolabs Symfony, published on 3 Feb 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-285
