Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

PHP Object Injection: Insecure deserialization of session data in the SessionCookie middleware allows remote attackers to inject arbitrary PHP objects, leading to arbitrary code execution if crafted session data is processed.

Reflected XSS: Unsanitized HttpException titles and descriptions passed directly to the HTML error renderer allow attackers to execute arbitrary scripts in the context of the user's browser session via reflected XSS.
