CVE-2025-46171 1 Vbulletin 1 Vbulletin 2025-07-28 N/A N/A
vBulletin 3.8.7 is vulnerable to a denial-of-service condition via the misc.php?do=buddylist endpoint. If an authenticated user has a sufficiently large buddy list, processing the list can consume excessive memory, exhausting system resources and crashing the forum.
CVE-2025-48827 1 Vbulletin 1 Vbulletin 2025-06-25 N/A 9.8 CRITICAL
vBulletin 5.0.0 through 5.7.5 and 6.0.0 through 6.0.3 allows unauthenticated users to invoke protected API controllers' methods when running on PHP 8.1 or later, as demonstrated by the /api.php?method=protectedMethod pattern, as exploited in the wild in May 2025.
CVE-2025-48828 1 Vbulletin 1 Vbulletin 2025-06-25 N/A 8.1 HIGH
Certain vBulletin versions might allow attackers to execute arbitrary PHP code by abusing Template Conditionals in the template engine. By crafting template code in an alternative PHP function invocation syntax, such as the "var_dump"("test") syntax, attackers can bypass security checks and execute arbitrary PHP code, as exploited in the wild in May 2025.
CVE-2023-25135 1 Vbulletin 1 Vbulletin 2025-03-26 N/A 9.8 CRITICAL
vBulletin before 5.6.9 PL1 allows an unauthenticated remote attacker to execute arbitrary code via a crafted HTTP request that triggers deserialization. This occurs because verify_serialized checks that a value is serialized by calling unserialize and then checking for errors. The fixed versions are 5.6.7 PL1, 5.6.8 PL1, and 5.6.9 PL1.
CVE-2019-16759 1 Vbulletin 1 Vbulletin 2025-03-14 7.5 HIGH 9.8 CRITICAL
vBulletin 5.x through 5.5.4 allows remote command execution via the widgetConfig[code] parameter in an ajax/render/widget_php routestring request.
CVE-2020-17496 1 Vbulletin 1 Vbulletin 2025-03-14 7.5 HIGH 9.8 CRITICAL
vBulletin 5.5.4 through 5.6.2 allows remote command execution via crafted subWidgets data in an ajax/render/widget_tabbedcontainer_tab_panel request. NOTE: this issue exists because of an incomplete fix for CVE-2019-16759.
CVE-2020-12720 1 Vbulletin 1 Vbulletin 2022-04-27 7.5 HIGH 9.8 CRITICAL
vBulletin before 5.5.6pl1, 5.6.0 before 5.6.0pl1, and 5.6.1 before 5.6.1pl1 has incorrect access control.
CVE-2020-7373 1 Vbulletin 1 Vbulletin 2021-07-21 7.5 HIGH 9.8 CRITICAL
vBulletin 5.5.4 through 5.6.2 allows remote command execution via crafted subWidgets data in an ajax/render/widget_tabbedcontainer_tab_panel request. NOTE: this issue exists because of an incomplete fix for CVE-2019-16759. ALSO NOTE: CVE-2020-7373 is a duplicate of CVE-2020-17496. CVE-2020-17496 is the preferred CVE ID to track this vulnerability.

CVE-2017-17671 2 Microsoft, Vbulletin 2 Windows, Vbulletin 2020-08-14 7.5 HIGH 9.8 CRITICAL
vBulletin through 5.3.x on Windows allows remote PHP code execution because a require_once call is reachable with an unauthenticated request that can include directory traversal sequences to specify an arbitrary pathname, and because ../ traversal is blocked but ..\ traversal is not blocked. For example, an attacker can make an invalid HTTP request containing PHP code, and then make an index.php?routestring= request with enough instances of ".." to reach an Apache HTTP Server log file.
