Air carrier flight crew reported receiving master caution and ECAM alerts for engine wing leak on both engines resulting in a cabin pressure loss while in cruise. Flight crew diverted to an alternate airport.

Narrative

During cruise flight at FL380; Master Caution with associated aural and ECAM indicated an Eng (1) Wing Leak. As we were assessing the situation and starting non-normal procedures; we received an additional ECAM - 1 min later - Eng (2) Wing Leak. As Pilot Flying (PF); First Officer (FO) assumed all radio calls while maintaining aircraft control. Captain continued troubleshooting; referring back to the QRC to see if this 'dual' Eng Wing Leak was an ECAM bypass item (knowing 'single' was not). It was not; though it was noticed that Eng 1+2 Bleed Fault was. While starting on ECAM actions for 'dual' Wing Leak; we received a subsequent Caution and ECAM of Eng 1+2 Bleed Fault. Captain paused Wing Leak ECAM actions knowing this new non-normal was a bypass item with potentially more risk. While reading QRH notes re: potential excessive CAB ALT; FO noticed and verbalized quickly rising CAB ALT. In short order we received a Master Warning and CABIN PR EXCESS CAB ALT ECAM. An Emergency Descent was initiated (to 12000 ft; per ATC) and [priority handling was requested]. Once stabilized at 12K ft; Captain continued with Eng 1+2 Bleed Fault procedures. Normal bleed pressure was regained after cycling Eng bleeds off then on. Divert to ZZZ was agreed upon and coordinated via ATC. Captain notified Dispatch via SATCOM; and communicated events and plan to Inflight team and passengers.Cabin 02 masks did not deploy; max observed CAB ALT was 12200. Flight; landing; taxi to gate in ZZZ were uneventful.
