Vulnerabilities

index.php?p=/dashboard/settings/branding in Vanilla 2.6.3 allows stored XSS.

In Vanilla before 2.6.4, a flaw exists within the getSingleIndex function of the AddonManager class. The issue results in a require call using a crafted type value, leading to Directory Traversal with File Inclusion. An attacker can leverage this vulnerability to execute code under the context of the web server.

Multiple stored XSS in Vanilla Forums before 2.5 allow remote attackers to inject arbitrary JavaScript code into any message on forum.

Vanilla before 2.5.5 and 2.6.x before 2.6.2 allows Remote Code Execution because authenticated administrators have a reachable call to unserialize in the Gdn_Format class.

Vanilla 2.6.x before 2.6.4 allows remote code execution.

Vanilla before 2.6.1 allows XSS via the email field of a profile.

Vanilla before 2.6.1 allows SQL injection via an invitationID array to /profile/deleteInvitation, related to applications/dashboard/models/class.invitationmodel.php and applications/dashboard/controllers/class.profilecontroller.php.

In Vanilla before 2.6.1, the polling functionality allows Insecure Direct Object Reference (IDOR) via the Poll ID, leading to the ability of a single user to select multiple Poll Options (e.g., vote for multiple items).

Vanilla Forums below 2.1.5 are affected by CSRF leading to Deleting topics and comments from forums Admin access

The from method in library/core/class.email.php in Vanilla Forums before 2.3.1 allows remote attackers to spoof the email domain in sent messages and potentially obtain sensitive information via a crafted HTTP Host header, as demonstrated by a password reset request.
