| CVE-2024-52702 | 1 Mybb | 1 Mybb | 2025-07-07 | 6.1 Medium |
| A stored cross-site scripting (XSS) vulnerability in the component install\index.php of MyBB v1.8.38 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Website Name parameter. | ||||
| CVE-2025-48940 | 1 Mybb | 1 Mybb | 2025-07-02 | 7.2 High |
| MyBB is free and open source forum software. Prior to version 1.8.39, the upgrade component does not validate user input properly, which allows attackers to perform local file inclusion (LFI) via a specially crafted parameter value. In order to exploit the vulnerability, the installer must be unlocked (no `install/lock` file present) and the upgrade script must be accessible (by re-installing the forum via access to `install/index.php`; when the forum has not yet been installed; or the attacker is authenticated as a forum administrator). MyBB 1.8.39 resolves this issue. | ||||
| CVE-2025-48941 | 1 Mybb | 1 Mybb | 2025-07-02 | 5.3 Medium |
| 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 displaying the final search results, a search operation that internally produces at least one result outputs a redirect response (as a HTTP redirect, or a success message page with delayed redirect, depending on configuration). On the other hand, a search operation that internally produces no results outputs a corresponding message in the response without a redirect. This allows a user to determine whether threads matching title search parameters exist, including draft threads (`visible` with a value of `-2`), soft-deleted threads (`visible` with a value of `-1`), and unapproved threads (`visible` with a value of `0`); in addition to displaying generally visible threads (`visible` with a value of `1`). This vulnerability does not affect other layers of permissions. In order to exploit the vulnerability, the user must have access to the search functionality, and general access to forums containing the thread(s). The vulnerability does not expose the message content of posts. MyBB 1.8.39 resolves this issue. | ||||
| CVE-2019-3578 | 1 Mybb | 1 Mybb | 2025-06-30 | 6.1 Medium |
| MyBB 1.8.19 has XSS in the resetpassword function. | ||||
| CVE-2019-3579 | 1 Mybb | 1 Mybb | 2025-06-30 | 5.3 Medium |
| MyBB 1.8.19 allows remote attackers to obtain sensitive information because it discloses the username upon receiving a password-reset request that lacks the code parameter. | ||||
| CVE-2024-23336 | 1 Mybb | 1 Mybb | 2025-06-30 | 5 Medium |
| MyBB is a free and open source forum software. The default list of disallowed remote hosts does not contain the `127.0.0.0/8` block, which may result in a Server-Side Request Forgery (SSRF) vulnerability. The Configuration File's _Disallowed Remote Addresses_ list (`$config['disallowed_remote_addresses']`) contains the address `127.0.0.1`, but does not include the complete block `127.0.0.0/8`. MyBB 1.8.38 resolves this issue in default installations. Administrators of installed boards should update the existing configuration (`inc/config.php`) to include all addresses blocked by default. Additionally, users are advised to verify that it includes any other IPv4 addresses resolving to the server and other internal resources. Users unable to upgrade may manually add 127.0.0.0/8' to their disallowed address list. | ||||
| CVE-2024-23335 | 1 Mybb | 1 Mybb | 2025-06-30 | 4.7 Medium |
| MyBB is a free and open source forum software. The backup management module of the Admin CP may accept `.htaccess` as the name of the backup file to be deleted, which may expose the stored backup files over HTTP on Apache servers. MyBB 1.8.38 resolves this issue. Users are advised to upgrade. There are no known workarounds for this vulnerability | ||||
| CVE-2025-29459 | 1 Mybb | 1 Mybb | 2025-06-27 | 7.6 High |
| An issue in MyBB 1.8.38 allows a remote attacker to obtain sensitive information via the Mail function. NOTE: the Supplier disputes this because of the allowed actions of Board administrators and because of SSRF mitigation. | ||||
| CVE-2022-43708 | 1 Mybb | 1 Mybb | 2025-04-29 | 6.1 Medium |
| MyBB 1.8.31 has a (issue 2 of 2) cross-site scripting (XSS) vulnerabilities in the post Attachments interface allow attackers to inject HTML by persuading the user to upload a file with specially crafted name | ||||
| CVE-2022-43707 | 1 Mybb | 1 Mybb | 2025-04-29 | 6.1 Medium |
| MyBB 1.8.31 has a Cross-site scripting (XSS) vulnerability in the visual MyCode editor (SCEditor) allows remote attackers to inject HTML via user input or stored data | ||||
| CVE-2022-43709 | 1 Mybb | 1 Mybb | 2025-04-29 | 4.9 Medium |
| MyBB 1.8.31 has a SQL injection vulnerability in the Admin CP's Users module allows remote authenticated users to modify the query string via direct user input or stored search filter settings. | ||||
| CVE-2025-29460 | 1 Mybb | 1 Mybb | 2025-04-25 | 7.6 High |
| An issue in MyBB 1.8.38 allows a remote attacker to obtain sensitive information via the Add Mycode function. NOTE: the Supplier disputes this because of the allowed actions of Board administrators and because of SSRF mitigation. | ||||
| CVE-2025-29458 | 1 Mybb | 1 Mybb | 2025-04-24 | 7.6 High |
| An issue in MyBB 1.8.38 allows a remote attacker to obtain sensitive information via the Change Avatar function. NOTE: the Supplier disputes this because of the allowed actions of Board administrators and because of SSRF mitigation. | ||||
| CVE-2025-29457 | 1 Mybb | 1 Mybb | 2025-04-24 | 7.6 High |
| An issue in MyBB 1.8.38 allows a remote attacker to obtain sensitive information via the Import a Theme function. NOTE: the Supplier disputes this because of the allowed actions of Board administrators and because of SSRF mitigation. | ||||
| CVE-2022-24734 | 1 Mybb | 1 Mybb | 2025-04-22 | 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-2022-39265 | 1 Mybb | 1 Mybb | 2025-04-22 | 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-2015-8977 | 1 Mybb | 2 Merge System, Mybb | 2025-04-20 | N/A |
| MyBB (aka MyBulletinBoard) before 1.6.18 and 1.8.x before 1.8.6 and MyBB Merge System before 1.8.6 allow remote attackers to obtain the installation path via vectors involving error log files. | ||||
| CVE-2015-8975 | 1 Mybb | 2 Merge System, Mybb | 2025-04-20 | N/A |
| Cross-site scripting (XSS) vulnerability in the error handler in MyBB (aka MyBulletinBoard) before 1.6.18 and 1.8.x before 1.8.6 and MyBB Merge System before 1.8.6 might allow remote attackers to inject arbitrary web script or HTML via unspecified vectors. | ||||
