Summary
The IETF Datatracker, before the fix in its 12.83.0 release, contains an authorization bypass in its NomCom views that lets a user holding a NomCom role reach other committees' records by changing sequential primary keys. An attacker who is logged in over the network with a low-privilege NomCom role can view confidential nominee identities, reclassify feedback, and change nominee email addresses.
