What is CVE-2024-9662?

The CYAN Backup WordPress plugin prior to version 2.5.3 harbors a vulnerability where certain settings are not properly sanitized and escaped. This oversight can be exploited by high-privilege users, including administrators, to execute Stored Cross-Site Scripting (XSS) attacks, even in environments where the unfiltered_html capability is restricted, such as in multisite setups. Implementing recent updates is crucial to mitigate this security risk.

Affected Version(s)

CYAN Backup 0 < 2.5.3

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.
