CVE-2021-32755

Name of the Vulnerable Software and Affected Versions Wire versions 3.82 through 3.83

Description The issue concerns the Wire collaboration platform, specifically the wire-ios-transport component that handles authentication and network failures for the iOS implementation. A new web socket implementation was introduced in version 3.82 for users running iOS 13 or higher, but it does not enforce certificate pinning when available. This lack of certificate pinning could potentially allow for man-in-the-middle attacks. Certificate pinning is enforced in versions 3.84 and above.

Recommendations For versions 3.82 and 3.83, update to version 3.84 or above to enforce certificate pinning for the new web socket implementation.
