Detailed vulnerability description

The vulnerability allows a remote attacker to obtain password or username reset links over an unencrypted connection.

The vulnerability exists due to improper transport layer protection in the password and username reset features when generating reset links for https connections without the "Force SSL" flag explicitly set. A remote attacker can trigger generation of a reset link that uses plain http to obtain password or username reset links over an unencrypted connection.

Only installations where the "Force SSL" flag is not explicitly set are vulnerable.
