CVE-2022-39265 1 Mybb 1 Mybb 2023-03-01 N/A 7.2 HIGH
MyBB is a free and open source forum software. The _Mail Settings_ ? Additional Parameters for PHP's mail() function mail_parameters setting value, in connection with the configured mail program's options and behavior, may allow access to sensitive information and Remote Code Execution (RCE). The vulnerable module requires Admin CP access with the `_Can manage settings?_` permission and may depend on configured file permissions. MyBB 1.8.31 resolves this issue with the commit `0cd318136a`. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2022-45867 1 Mybb 1 Mybb 2023-01-09 N/A 7.2 HIGH
MyBB before 1.8.33 allows Directory Traversal. The Admin CP Languages module allows remote authenticated users, with high privileges, to achieve local file inclusion and execution.
CVE-2022-43709 1 Mybb 1 Mybb 2022-11-22 N/A 4.9 MEDIUM

CVE-2022-24734 1 Mybb 1 Mybb 2022-09-30 6.5 MEDIUM 7.2 HIGH
MyBB is a free and open source forum software. In affected versions the Admin CP's Settings management module does not validate setting types correctly on insertion and update, making it possible to add settings of supported type `php` with PHP code, executed on on _Change Settings_ pages. This results in a Remote Code Execution (RCE) vulnerability. The vulnerable module requires Admin CP access with the `Can manage settings?` permission. MyBB's Settings module, which allows administrators to add, edit, and delete non-default settings, stores setting data in an options code string ($options_code; mybb_settings.optionscode database column) that identifies the setting type and its options, separated by a new line character (\n). In MyBB 1.2.0, support for setting type php was added, for which the remaining part of the options code is PHP code executed on Change Settings pages (reserved for plugins and internal use). MyBB 1.8.30 resolves this issue. There are no known workarounds.
CVE-2021-43281 1 Mybb 1 Mybb 2021-11-05 6.5 MEDIUM 7.2 HIGH
MyBB before 1.8.29 allows Remote Code Injection by an admin with the "Can manage settings?" permission.

CVE-2020-15139 1 Mybb 1 Mybb 2020-08-13 4.3 MEDIUM 6.1 MEDIUM
In MyBB before version 1.8.24, the custom MyCode (BBCode) for the visual editor doesn't escape input properly when rendering HTML, resulting in a DOM-based XSS vulnerability. The 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 saved malicious message is quoted. After upgrading MyBB to 1.8.24, make sure to update the version attribute in the `codebuttons` template for non-default themes to serve the latest version of the patched `jscripts/bbcodes_sceditor.js` file.
CVE-2014-3827 1 Mybb 1 Mybb 2020-02-12 3.5 LOW 5.4 MEDIUM
Multiple cross-site scripting (XSS) vulnerabilities in the MyBB (aka MyBulletinBoard) before 1.8.4 allow remote authenticated users to inject arbitrary web script or HTML via the title parameter in the (1) edit or (2) add action in the user-users module or the (3) finduser action or the name parameter in an (4) edit action in the user-user module or the (5) editprofile action to modcp.php.
