PHP remote file inclusion vulnerability in classes/core/language.php in LimeSurvey 1.5.2 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the rootdir parameter.

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.

LimeSurvey 2.0+ - 2.06+ Unauthenticated Arbitrary File Download via Serialized Backup Payload

An unauthenticated file download vulnerability exists in LimeSurvey versions from 2.0+ up to and including 2.06+ Build 151014. The application fails to validate serialized input to the admin backup endpoint (`index.php/admin/update/sa/backup`), allowing attackers to specify arbitrary file paths using a crafted `datasupdateinfo` payload. The files are packaged in a ZIP archive and made available for download without authentication. This vulnerability can be exploited to read arbitrary files on the host system, including sensitive OS and configuration files.

SQL Injection vulnerability in LimeSurvey before v.6.15.4+250710 allows a remote attacker to obtain sensitive information from the database.

Multiple vulnerabilities in Limesurvey

Vulnerability in LimeSurvey 6.13.0 in the endpoint /optout that causes infinite HTTP redirects when accessed directly.

The system is unable to break the redirect loop, which can cause service degradation or browser instability.

Multiple vulnerabilities in Limesurvey

Vulnerability in LimeSurvey 6.13.0 in the endpoint /optin that causes infinite HTTP redirects when accessed directly. This behavior can be exploited to generate a Denegation of Service (DoS attack), by exhausting server or client resources. The system is unable to break the redirect loop, which can cause service degradation or browser instability.

Multiple vulnerabilities in Limesurvey

In version 6.13.0 of LimeSurvey, any external user can cause a 500 error in the survey system by sending a malformed session cookie. Instead of displaying a generic error message, the system exposes internal backend information, including the use of the Yii framework, the MySQL/MariaDB database engine, the table name 'lime_sessions', primary keys, and fragments of the content that caused the conflict. This information can simplify the collection of data about the internal architecture of the application by an attacker.

A CSV injection vulnerability in Lime Survey v6.5.12 allows attackers to execute arbitrary code via uploading a crafted CSV file.

An issue in the js_localize.php function of LimeSurvey v6.6.2 and before allows attackers to execute arbitrary code via injecting a crafted payload into the lng parameter of the js_localize.php function
