These are the five CVEs with the highest CVSS scores for vbulletin, sorted by severity first and recency.
A cross-site scripting (XSS) vulnerability in the Admin Control Panel of vBulletin 5.7.5 and 6.0.0 allows attackers to execute arbitrary web scripts or HTML via the /login.php?do=login url parameter.
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.
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.
The Admin CP in vBulletin 5.6.3 allows XSS via an admincp/attachment.php&do=rebuild&type= URI.
The Admin CP in vBulletin 5.6.3 allows XSS via a Smilie Title to Smilies Manager.
The Admin CP in vBulletin 5.6.3 allows XSS via a Rank Type to User Rank Manager.
The Admin CP in vBulletin 5.6.3 allows XSS via the Paid Subscription Email Notification field in the Options.
The Admin CP in vBulletin 5.6.3 allows XSS via the admincp/search.php?do=dosearch URI.
The Admin CP in vBulletin 5.6.3 allows XSS via a Title of a Child Help Item in the Login/Logoff part of the User Manual.
The Admin CP in vBulletin 5.6.3 allows XSS via a Style Options Settings Title to Styles Manager.
The Admin CP in vBulletin 5.6.3 allows XSS via a Junior Member Title to User Title Manager.
The Admin CP in vBulletin 5.6.3 allows XSS via an Announcement Title to Channel Manager.
The Admin CP in vBulletin 5.6.3 allows XSS via an Occupation Title or Description to User Profile Field Manager.
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.
vBulletin before 5.5.6pl1, 5.6.0 before 5.6.0pl1, and 5.6.1 before 5.6.1pl1 has incorrect access control.
vBulletin 5.5.4 allows SQL Injection via the ajax/api/hook/getHookList or ajax/api/widget/getWidgetList where parameter.
vBulletin through 5.5.4 mishandles custom avatars.
vBulletin before 5.5.4 allows clickjacking.
vBulletin through 5.5.4 mishandles external URLs within the /core/vb/vurl.php file and the /core/vb/vurl directories.
vBulletin 5.x through 5.5.4 allows remote command execution via the widgetConfig[code] parameter in an ajax/render/widget_php routestring request.
vBulletin 5.4.3 has an Open Redirect.
vBulletin 3.x.x and 4.2.x through 4.2.5 has an open redirect via the redirector.php url parameter.
In vBulletin through 5.3.x, there is an unauthenticated deserialization vulnerability that leads to arbitrary file deletion and, under certain circumstances, code execution, because of unsafe usage of PHP's unserialize() in vB_Library_Template's cacheTemplates() function, which is a publicly exposed API. This is exploited with the templateidlist parameter to ajax/api/template/cacheTemplates.
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.
vBulletin 5.x through 5.1.6 allows remote authenticated users to bypass authorization checks and inject private messages into conversations via vectors related to an input validation failure.
Cross-site scripting (XSS) vulnerability in vBulletin 3.5.4, 3.6.0, 3.6.7, 3.8.7, 4.2.2, 5.0.5, and 5.1.3.

SQL injection vulnerability in forumrunner/includes/moderation.php in vBulletin before 4.2.2 Patch Level 5 and 4.2.3 before Patch Level 1 allows remote attackers to execute arbitrary SQL commands via the postids parameter to forumrunner/request.php, as exploited in the wild in July 2016.
The vB_Api_Hook::decodeArguments method in vBulletin 5 Connect 5.1.2 through 5.1.9 allows remote attackers to conduct PHP object injection attacks and execute arbitrary PHP code via a crafted serialized object in the arguments parameter to ajax/api/hook/decodeArguments.
Cross-site request forgery (CSRF) vulnerability in the Moderator Control Panel in vBulletin 4.2.2 allows remote attackers to hijack the authentication of administrators for requests that (1) ban a user via the username parameter in a dobanuser action to modcp/banning.php or (2) unban a user, (3) modify user profiles, edit a (4) post or (5) topic, or approve a (6) post or (7) topic via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in vBulletin 5.1.1 Alpha 9 allow remote attackers to inject arbitrary web script or HTML via (1) the PATH_INFO to privatemessage/new/, (2) the folderid parameter to a private message in privatemessage/view, (3) a fragment indicator to /help, or (4) the view parameter to a topic, as demonstrated by a request to forum/anunturi-importante/rst-power/67030-rst-admin-restore.
The install/upgrade.php scripts in vBulletin 4.1 and 5 allow remote attackers to create administrative accounts via the customerid, htmldata[password], htmldata[confirmpassword], and htmldata[email] parameters, as exploited in the wild in October 2013.
SQL injection vulnerability in index.php/ajax/api/reputation/vote in vBulletin 5.0.0 Beta 11, 5.0.0 Beta 28, and earlier allows remote authenticated users to execute arbitrary SQL commands via the nodeid parameter.
