An authenticated LimeSurvey Community Edition 7.3.0 user allowed to create surveys can use their own survey as an authorized context while supplying question or answer identifiers belonging to another user's survey. The REST survey-patching endpoint checks the attacker's permission against the survey ID in the request URL, but the vulnerable persistence operations resolve the target object independently by its global qid or aid and never verify that it belongs to that authorized survey.

LimeSurvey Community Edition 7.0.14 fails to safely encode attacker-controlled content from a crafted .lss survey file when displaying import warnings, resulting in XSS in the administrative interface.

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.
