Wordfence Intelligence > Vulnerability Database > Web Instant Messenger <= 1.1.2 and LocalWeb In One <= 1.6.4 - Stored Cross-Site Scripting

7.2

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N

CVSS	7.2 (High)
Publicly Published	October 12, 2020
Last Updated	January 22, 2024
Researcher	RE-ALTER

Description

The Web Instant Messenger and LocalWeb In One plugins for WordPress are vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.6.4 (NOTE: Web Instant Messenger's latest version 1.1.2 is unpatched) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
