The PixelYourSite WordPress plugin and its Pro version contain a security flaw that fails to sanitize and escape cookie values prior to their display in the page output. This vulnerability can be exploited on websites utilizing full-page caching, as it allows unauthorized attackers to inject Cross-Site Scripting (XSS) payloads. Consequently, the malicious code may be stored in the cached page and subsequently served to unsuspecting users, posing significant risks to site security and integrity.

PixelYourSite 0 < 11.4.3

PixelYourSite Pro 0 < 12.6.8

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.
