CVE-2018-10305
The MessageSearch2 function in PersonalMessage.php in Simple Machines Forum (SMF) before 2.0.15 does not properly use the possible_users variable in a query, which might allow attackers to bypass intended access restrictions.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
