Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
ext/session/session.c in PHP before 5.6.25 and 7.x before 7.0.10 skips invalid session names in a way that triggers incorrect parsing, which allows remote attackers to inject arbitrary-type session data by leveraging control of a session name, as demonstrated by object injection.
