The WP-Spreadplugin by Thimo Grauerholz contains an XSS vulnerability due to improper input neutralization during web page generation. This flaw affects all versions through 4.8.9. Exploitation requires high privileges and user interaction, and it can lead to partial confidentiality, integrity, and availability impacts. The vulnerability is tracked as CVE-2024-49266 with a CVSS 3.1 base score of 5.9 (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L). No patch or vendor advisory is currently provided.

Successful exploitation could allow an attacker with high privileges to execute arbitrary scripts in the context of the affected application, potentially leading to limited confidentiality, integrity, and availability impacts. The requirement for user interaction and high privileges reduces the overall risk. There are no known exploits in the wild at this time.
