CVE-2022-1530Network attack vector

Browser script execution through undisclosed XSS vector

Published Apr 29, 2022 · Updated Aug 3, 2024

Cross-site scripting in Live Helper Chat before 3.99 allows remote attackers to execute JavaScript in a user's browser. Neither the CNA description nor the referenced 3.99 patch identifies the affected request, input field, rendering sink, or missing neutralization operation. Published assessments disagree on access conditions: NVD requires victim interaction without authentication, while the CNA requires high privileges and no interaction.
