Briar before 1.4.22 allows attackers to spoof other users messages in a blog, forum, or private group, but each spoofed message would need to be an exact duplicate of a legitimate message displayed alongside the spoofed one.
The product does not validate or incorrectly validates the integrity check values or “checksums” of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission.
