Description ybuenos 2024-04-15 07:29:30 UTC

Due to an incomplete fix to CVE-2022-31629, network and same-site attackers can set a standard insecure cookie in the victim's browser which is treated as a __Host- or __Secure- cookie by PHP applications.

The vulnerability is identical to one previously described in https://bugs.php.net/bug.php?id=81727. Unfortunatly, since CVE-2022-31629 got only partially fixed in PHP >8.1.11, cookies starting with _[Host- are parsed by PHP applications as __Host-.
