Title: notifications: adjust regex pattern Class: fix Compatible: compat Component: rest-api Date: 1695917741 Edition: cre Knowledge: doc Level: 1 State: unknown Version: 2.2.0p12 This werk addresses an issues found by the QA team with regards to the regex pattern we use to match valid PushOverPlugin api_keys and also the user group key. Previously we used [a-zA-Z0-9]{30} which will match any string that has 30 or more characters and numbers. This is partial match. We now do the following ^[a-zA-Z0-9]{30,40}$ which will match the whole string. We only allow characters and numbers with the whole string having to be of length min 30 and max 40 characters.
