Technical details
A Cross-Site Scripting (XSS) vulnerability exists in the ShortPixel Adaptive Images plugin for WordPress due to improper neutralization of input during web page generation (CWE-79). The flaw allows an authenticated attacker with Subscriber-level privileges to inject arbitrary JavaScript into the application. Successful exploitation requires a victim (such as an administrator) to perform a specific action, such as visiting a crafted page or clicking a malicious link, which triggers the execution of the script in the context of the victim's session. This can lead to session hijacking or unauthorized administrative actions. The issue is resolved in version 3.11.4.
