LimeSurvey through 6.17.10 and 7.0.4 contains a server-side request forgery vulnerability in the REST API survey template endpoint that allows authenticated users to cause the server to issue arbitrary HTTP requests by supplying a manipulated Host header. Attackers can exploit the unsanitized use of the HTTP Host header in the getTemplateData() function to reach internal network services, cloud metadata endpoints, and extract sensitive credentials such as IAM tokens from instance metadata services.

Cross-site scripting (XSS) vulnerability in /application/controller/admin/theme.php in LimeSurvey 3.6.2+180406 allows remote attackers to inject arbitrary web script or HTML via the changescp parameter to the index.php/admin/themes/sa/templatesavechanges URI.

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 RemoteControl API methods inviteparticipants and remindparticipants 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 statements (INSERT/UPDATE/DELETE/DROP/CREATE) after the original SELECT. This permits both arbitrary read of any data in the database, such as administrator bcrypt password hashes (limeusers), survey response PII, session records, and global settings, all recoverable via a SLEEP() time-based blind oracle, and arbitrary write/destruction of that data, including directly overwriting the administrator password hash for immediate account takeover or dropping/truncating tables. Reads and writes extend to any schema the application's database user can access. The RemoteControl interface (RPCInterface = json/xml) must be enabled, which is not the default.

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 validationkey. When the recipient or an automated inbound mail-security link scanner dereferences the link, the valid reset token is disclosed to the attacker, who replays it against the legitimate host's newPassword endpoint to set a new password and take over the account.

LimeSurvey 4.3.10 contains a stored cross-site scripting vulnerability in the Survey Menu functionality of the administration panel. Attackers can inject malicious SVG scripts through the Surveymenu[title] and Surveymenu[parentid] parameters to execute arbitrary JavaScript in administrative contexts.

A flaw has been found in LimeSurvey 6.5.14-240624. Affected by this issue is the function actionUpdateSurveyLocaleSettingsGeneralSettings of the file /index.php?r=admin/database/index/updatesurveylocalesettingsgeneralsettings of the component Survey General Settings Handler. This manipulation of the argument Language causes sql injection. The attack is possible to be carried out remotely. The exploit has been published and may be used. Upgrading to version 6.6.2+240827 can resolve this issue. Patch name: d656d2c7980b7642560977f4780e64533a68e13d. You should upgrade the affected component.

LimeSurvey before v5.0.4 was discovered to contain a SQL injection vulnerability via the component /application/views/themeOptions/update.php.

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 2.6.x before 2.6.7, 2.7x.x before 2.73.1, and 3.x before 3.4.2 mishandles application/controller/InstallerController.php after installation, which allows remote attackers to access the configuration file.

A Reflected Cross-Site Scripting (XSS) affects LimeSurvey versions prior to 6.15.11+250909, due to the lack of validation of gid parameter in getInstance() function in application/models/QuestionCreate.php. This allows an attacker to craft a malicious URL and compromise the logged in user.

Cross Site Scripting (XSS) vulnerability in Lime Survey Community Edition Version v.5.3.32+220817, allows remote attackers to execute arbitrary code via the Administrator email address parameter in the General Setting function.

Lime Survey <= 6.5.12 is vulnerable to Cross Site Request Forgery (CSRF). The YIICSRFTOKEN is only checked when passed in the body of POST requests, but the same check isn't performed in the equivalent GET requests.

A vulnerability was found in LimeSurvey 6.3.0-231016 and classified as problematic. Affected by this issue is some unknown functionality of the file /index.php of the component File Upload. The manipulation of the argument size leads to denial of service. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
