| Multiple SQL injection vulnerabilities in MyBB 1.2.10 and earlier allow remote moderators and administrators to execute arbitrary SQL commands via (1) the mergepost parameter in a do_mergeposts action, (2) rid parameter in an allreports action, or (3) threads parameter in a do_multimovethreads action to (a) moderation.php; or (4) gid parameter to (b) admin/usergroups.php. | ||||
| CVE-2009-4448 | 1 Mybb | 1 Mybb | 2026-04-23 | N/A |
| inc/functions_time.php in MyBB (aka MyBulletinBoard) 1.4.10, and possibly earlier versions, allows remote attackers to cause a denial of service (CPU consumption) via a crafted request with a large year value, which triggers a long loop, as reachable through member.php and possibly other vectors. | ||||
| CVE-2018-25250 | 1 Mybb | 2 Last User Threads, Mybb | 2026-04-20 | 7.2 High |
| MyBB Last User's Threads in Profile Plugin 1.2 contains a persistent cross-site scripting vulnerability that allows attackers to inject malicious scripts by crafting thread subjects with script tags. Attackers can create threads with script payloads in the subject field that execute when users visit the attacker's profile page. | ||||
| CVE-2018-25247 | 1 Mybb | 3 Mybb, Mybb Like Plugin, Thankyou\/like System | 2026-04-20 | 6.1 Medium |
| 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. | ||||
| CVE-2006-0442 | 1 Mybb | 1 Mybb | 2026-04-16 | N/A |
| Multiple cross-site scripting (XSS) vulnerabilities in usercp.php in MyBulletinBoard (MyBB) 1.02 allow remote attackers to inject arbitrary web script or HTML via the (1) notepad parameter in a notepad action and (2) signature parameter in an editsig action. NOTE: These are different attack vectors, and probably a different vulnerability, than CVE-2006-0218 and CVE-2006-0219. | ||||
| CVE-2006-0218 | 1 Mybb | 1 Mybb | 2026-04-16 | N/A |
| Multiple unspecified vulnerabilities in MyBulletinBoard (MyBB) before 1.0.2 have unspecified impact and attack vectors, related to (1) admin/moderate.php, (2) admin/themes.php, (3) inc/functions.php, (4) inc/functions_upload.php, (5) printthread.php, and (6) usercp.php, and probably related to SQL injection. NOTE: it is likely that this issue subsumes CVE-2005-4602 and CVE-2005-4603. However, since the vendor advisory is vague and additional files are mentioned, is is likely that this contains at least one distinct vulnerability from CVE-2005-4602 and CVE-2005-4603. | ||||
| CVE-2005-4199 | 1 Mybb | 1 Mybb | 2026-04-16 | N/A |

| CVE-2011-10018 | 1 Mybb | 1 Mybb | 2026-04-07 | 9.8 Critical |
| myBB version 1.6.4 was distributed with an unauthorized backdoor embedded in the source code. The backdoor allowed remote attackers to execute arbitrary PHP code by injecting payloads into a specially crafted collapsed cookie. This vulnerability was introduced during packaging and was not part of the intended application logic. Exploitation requires no authentication and results in full compromise of the web server under the context of the web application. | ||||
| CVE-2023-53979 | 1 Mybb | 1 Mybb | 2026-03-05 | 8.8 High |
| MyBB 1.8.32 contains a chained vulnerability that allows authenticated administrators to bypass avatar upload restrictions and execute arbitrary code.

| CVE-2024-52702 | 1 Mybb | 1 Mybb | 2025-12-08 | 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. NOTE: this is disputed by the Supplier because Website Name can only be set by an administrator, who may use JavaScript if they wish. | ||||
| CVE-2009-4813 | 1 Mybb | 1 Mybb | 2025-09-26 | N/A |
| Cross-site scripting (XSS) vulnerability in myps.php in MyBB (aka MyBulletinBoard) 1.4.10 allows remote attackers to inject arbitrary web script or HTML via the username parameter in a donate action. | ||||
| CVE-2010-5096 | 1 Mybb | 1 Mybb | 2025-09-26 | N/A |
| Multiple SQL injection vulnerabilities in MyBB (aka MyBulletinBoard) before 1.6.1 allow remote attackers to execute arbitrary SQL commands via the keywords parameter in a (1) do_search action to search.php or (2) do_stuff action to private.php. NOTE: the vendor disputes this issue, saying "Although this doesn't lead to an SQL injection, it does provide a general MyBB SQL error. | ||||
| 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. | ||||
