CVE-2019-10754
Multiple classes used within Apereo CAS before release 6.1.0-RC5 makes use of apache commons-lang3 RandomStringUtils for token and ID generation which makes them predictable due to RandomStringUtils PRNG's algorithm not being cryptographically strong.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
