The RemoteControl API methods invite_participants and remind_participants pass a caller-supplied token-ID array into TokenDynamic::findUninvited(), which concatenates the values directly into a tid IN ('...') SQL clause without parameterization or input validation. A remote, authenticated attacker holding the tokens/update permission on a survey can inject a crafted array element to perform SQL injection. Because LimeSurvey configures its PDO connection with emulated prepared statements (emulatePrepare = true) and does not disable MySQL multi-statements, the injection supports stacked queries: the attacker can append arbitrary additional stat
LimeSurvey constructs account password-reset links from the client-supplied HTTP Host header without validating it. The optional allowedHosts allowlist that would constrain this is undefined in the default (and documented) configuration, so LSHttpRequest::checkIsAllowedHost() results in no operation. A remote, unauthenticated attacker who submits a forgotten-password request for a known account (requiring only the target's username and email) with a spoofed Host header causes LimeSurvey to email that account a reset link whose hostname is attacker-controlled while embedding the genuine validation_key. When the recipient or an automated inboun
Cross Site Scripting vulnerability in LimeSurvey before 6.5.0+240319 allows a remote attacker to execute arbitrary code via a lack of input validation and output encoding in the Alert Widget's message component.
Cross Site Scripting vulnerability in LimeSurvey before 6.5.12+240611 allows a remote attacker to execute arbitrary code via a crafted script to the title and comment fields.
The "File upload question" functionality in LimeSurvey 3.x-LTS through 3.27.18 allows XSS in assets/scripts/modaldialog.js and assets/scripts/uploader.js.
LimeSurvey before v3.17.14 allows stored XSS for escalating privileges from a low-privileged account to, for example, SuperAdmin. The attack uses a survey group in which the title contains JavaScript that is mishandled upon group deletion.
LimeSurvey before v3.17.14 allows reflected XSS for escalating privileges from a low-privileged account to, for example, SuperAdmin. This occurs in application/core/Survey_Common_Action.php,
