WpEstate Wpresidence Core versions up to 5.4.0 contain a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows an attacker with low privileges and requiring user interaction to inject malicious scripts that execute in the context of other users, potentially leading to limited confidentiality, integrity, and availability impacts. The vulnerability has a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L). No patch or official vendor advisory is currently referenced, and no exploits are known in the wild.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to limited disclosure of information, modification of data, or disruption of service. The impact is rated medium based on the CVSS score and vector, reflecting the need for user interaction and low privileges but with potential cross-site scripting consequences.
