LimeSurvey Community Edition 7.0.14 contains a reflected cross-site scripting vulnerability on the administrative survey-participant CSV import result page.
AnalysisAI
Reflected cross-site scripting (XSS) in LimeSurvey Community Edition 7.0.14 allows an attacker to execute arbitrary JavaScript in an authenticated administrator's browser when the admin imports a crafted CSV file of survey participants. The payload is reflected on the import result page via unencoded invalid attribute field names or duplicate record fields (firstname, lastname, email), requiring the attacker to social-engineer an admin into importing the malicious file. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated administrator to actively import an attacker-supplied CSV file through the survey-participant import feature (Tokens.php import()); the payload must be placed in a CSV column header treated as an invalid attribute field name, or in the firstname/lastname/email of a record flagged as a duplicate, since those are the values reflected unescaped on the import result page. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a reflected XSS (CWE-79) with a moderate, conditional risk profile rather than a top-tier priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the upstream fix by updating to a LimeSurvey release that includes commit 0523de7bbb0282af33a0bf9e08a1fc6333ae6851 (https://github.com/LimeSurvey/LimeSurvey/commit/0523de7bbb0282af33a0bf9e08a1fc6333ae6851); no exact patched version number is available, so verify with the vendor. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, confirm whether LimeSurvey Community Edition 7.0.14 is deployed in your environment, identify the administrators who perform participant CSV imports, and instruct them to treat unsolicited or unexpected participant files as untrusted; verify that the vendor-released update addressing CVE-2026-92730 is available from the LimeSurvey advisory and begin change-control preparation for deployment. …
