MyBB (aka MyBulletinBoard) 1.4.2 uses insufficient randomness to compose filenames of uploaded files used as attachments, which makes it easier for remote attackers to read these files by guessing filenames.

Glexia's TakeAutomated analysis

Security readout for executives and security teams

MyBB 1.4.2 created attachment filenames with insufficient randomness. If a forum allowed attachments, a remote attacker could guess filenames and read uploaded files that should not be discoverable. The main business risk is unintended disclosure of private forum attachments, not system takeover. Exposure is most likely on internet-facing MyBB 1.4.2 installations with attachments enabled. The bundle’s affected product metadata is incomplete, listing n/a, but the title and description identify MyBB 1.4.2. Treat this as a high-priority legacy exposure issue if any MyBB 1.4.2 forum remains online. The likely impact is confidential attachment disclosure, which can create privacy, contractual, or reputational risk depending on forum contents. Mitigation focus: Inventory forums and confirm whether MyBB 1.4.2 is present.; Check MyBB vendor guidance or release notes for the fixed version.; Disable or restrict attachments until vendor remediation is confirmed..
