wireapp/wire-ios-transport

Wire-ios is a messaging application using the wire protocol on apple's ios platform. In versions prior to 3.95 malformed resource identifiers may render the iOS Wire Client completely unusable by causing it to repeatedly crash on launch. These malformed resource identifiers can be generated and sent between Wire users. The root cause lies in [wireapp/wire-ios-transport](https://github.com/wireapp/wire-ios-transport), where code responsible for removing sensible tokens before logging may fail and lead to a crash (Swift exception) of the application. This causes undesirable behavior, however the (greater) Wire system is still functional. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.

Wire is an open source secure messenger. In affected versions if the an attacker gets an old but valid access token they can take over an account by changing the email. This issue has been resolved in version 3.86 which uses a new endpoint which additionally requires an authentication cookie. See wire-ios-sync-engine and wire-ios-transport references. This is the root advisory that pulls the changes together.

Wire is a collaboration platform. wire-ios-transport handles authentication of requests, network failures, and retries for the iOS implementation of Wire. In the 3.82 version of the iOS application, a new web socket implementation was introduced for users running iOS 13 or higher. This new websocket implementation is not configured to enforce certificate pinning when available. Certificate pinning for the new websocket is enforced in version 3.84 or above.
