CVE-2019-12422
Apache Shiro before 1.4.2, when using the default "remember me" configuration, cookies could be susceptible to a padding attack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
