Multiple CredentialStores with ONE backed credential store file can rewrite values each other. ---------------------------------------------------------------------------------------------- Key: WFCORE-2490 URL: https://issues.jboss.org/browse/WFCORE-2490 Project: WildFly Core Issue Type: Bug Components: Security Reporter: Hynek Švábek Assignee: Peter Skopek Priority: Blocker Multiple CredentialStores with ONE backed credential store file can rewrite values each other. *How to reproduce* {code} /subsystem=elytron/credential-store=credStore001:add(uri="cr-store://test/cs001.jceks?store.password=pass123;create.storage=true") /subsystem=elytron/credential-store=credStore001/alias="alias1":add(secret-value=Elytron) {code} {code} /subsystem=elytron/credential-store=credStore002:add(uri="cr-store://test/cs001.jceks?store.password=pass123") {code} check CS file there is "alias1" entry {code} /subsystem=elytron/credential-store=credStore001/alias="alias2":add(secret-value=Elytron) {code} check CS file there are "alias1" and "alias2" entries {code} /subsystem=elytron/credential-store=credStore002/alias="alias123":add(secret-value=Elytron) {code} check CS file there are "alias1" and "alias123" entries". *NOTE* It is problem, because we have one backed file. In memory we have right values for all Credential Stores, but after restart we can lost new entries. In my opinion reason for this behaviour is: We have CS loaded in memory and when we add new alias to CS then we save whole CS from memory to file. We can set CS as non-modifiable when we use same backed file for CredentialStore but we must find better default behaviour. *My suggestion for default behaviour* When we want to add new alias to CredentialStore we can do this: # refresh CS from file (and this file lock) # add new alias to CS # save CS to file # unlock file *But there is posible problem with performance....*
