What is CVE-2026-19056?

The ProSolution WP Client plugin for WordPress, prior to version 2.0.11, contains a flaw that allows for reflected Cross-Site Scripting (XSS). This weakness arises from the improper sanitization and escaping of a parameter that is reflected in an HTML attribute on one of its administrative pages. As a result, an attacker could manipulate an administrator into submitting a maliciously crafted request, executing code within the context of the administrator's session and potentially compromising the security of the web application.

Affected Version(s)

ProSolution WP Client 0 < 2.0.11

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
