Description

MyBB Like Plugin 3.0.0 contains a cross-site scripting vulnerability that allows attackers to inject malicious scripts by creating posts or threads with unvalidated subject content. Attackers can craft post subjects containing script tags that execute when other users view the attacker's profile, where liked posts are displayed without sanitization.
