What is CVE-2025-6236?

The Hostel Plugin for WordPress prior to version 1.1.5.9 contains vulnerabilities related to improper data sanitization and escaping of its settings. This oversight allows users with high privileges, including administrators, to execute stored cross-site scripting (XSS) attacks. These attacks can be particularly impactful in multisite setups where the unfiltered_html capability is typically restricted, creating opportunities for exploitation despite such restrictions.

Affected Version(s)

Hostel 0 < 1.1.5.9

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.
