CVE-2026-116645

LimeSurvey Community Edition 7.8.0 - SQL injection via Archive Attributes

LimeSurvey Community Edition 7.8.0 contains an SQL injection vulnerability in the survey-archive participant import and SPSS-response export workflow. An authenticated user with global surveys.create permission can import a crafted .lsa archive whose participant XML creates an attacker-named attribute column. When the user exports responses from the imported non-anonymous survey, LimeSurvey passes the persisted name to Yii's select builder. Names containing parentheses are treated as SQL expressions instead of quoted identifiers, causing attacker-controlled SQL to execute with the application's database privileges.

CVE-2026-115640

LimeSurvey Community Edition 7.7.0 - Stored XSS in Central Participants blocklist control

LimeSurvey Community Edition 7.7.0 contains a stored cross-site scripting vulnerability in the Central Participants Database blocklist control. An authenticated user with only global participantpanel:import permission can import a CSV participant_id containing HTML. The import flow persists that value without model validation. When a CPDB editor opens the participant list, LimeSurvey derives ButtonGroupWidget id and name attributes from participant_id and inserts them without HTML encoding, causing attacker-controlled markup to execute in the victim's authenticated LimeSurvey origin. Exploitation can access session-exposed data and issue same-origin requests with the victim's effective permissions.
