Name of the Vulnerable Software and Affected Versions Wire versions prior to 3.86

Description The issue allows an attacker to take over an account by changing the email if they obtain an old but valid access token. This is possible due to insufficient security measures in place prior to the resolution in version 3.86. The new version introduces a new endpoint that requires an authentication cookie, enhancing security.

Recommendations For versions prior to 3.86, update to version 3.86 or later to resolve the issue. As a temporary workaround, consider restricting access to account settings until the update is applied.
