The PDOSessionHandler class allows storing sessions on a PDO connection.

MEDIUM 5.9EPSS 1.61%

Does this matter?

Lower severity and a low EPSS score (1.61%). Track it; it rarely justifies an emergency change on its own.

Description

An issue was discovered in the HttpFoundation component in Symfony 2.7.x before 2.7.48, 2.8.x before 2.8.41, 3.3.x before 3.3.17, 3.4.x before 3.4.11, and 4.0.x before 4.0.11. The PDOSessionHandler class allows storing sessions on a PDO connection. Under some configurations and with a well-crafted payload, it was possible to do a denial of service on a Symfony application without too much resources.
