CVE-2026-18109
A vulnerability exists in the W3 Total Cache plugin for WordPress, affecting versions up to 2.10.3, due to inadequate input validation and output encoding. This weakness allows unauthenticated attackers to inject malicious scripts into web pages, which will execute when a user accesses the compromised page, provided the Lazy Load Images feature is enabled. The vulnerability specifically arises from the plugin's handling of image tags when Lazy Load Images is active.
