02 Jun 2025 — MyBB is free and open source forum software. Prior to version 1.8.39, the search component does not validate permissions correctly, which allows attackers to determine the existence of hidden (draft, unapproved, or soft-deleted) threads containing specified text in the title. The visibility state (`mybb_threads.visible` integer column) of threads is not validated in internal search queries, whose result is used to output a general success or failure of the search. While MyBB validates permissions when displ... • https://github.com/mybb/mybb/commit/b8cc332a27e145c33effaccec90e23c103ae5193 • CWE-1230: Exposure of Sensitive Information Through Metadata •

CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-46251 – Visual editor persistent Cross-site Scripting (XSS) in MyBB
https://notcve.org/view.php?id=CVE-2023-46251
06 Nov 2023 — MyBB is a free and open source forum software. Custom MyCode (BBCode) for the visual editor (_SCEditor_) doesn't escape input properly when rendering HTML, resulting in a DOM-based XSS vulnerability. This weakness can be exploited by pointing a victim to a page where the visual editor is active (e.g. as a post or Private Message) and operates on a maliciously crafted MyCode message. This may occur on pages where message content is pre-filled using a GET/POST parameter, or on reply pages where a previously s... • https://github.com/mybb/mybb/commit/6dcaf0b4db6254f1833fe8dae295d9ddc2219276 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
