Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Blocksera Image Hover Effects Block allows Stored XSS. This issue affects Image Hover Effects Block: from n/a through 1.4.5.
AnalysisAI
Stored cross-site scripting in Image Hover Effects Block for WordPress up to version 1.4.5 allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These scripts execute when other users view the affected page, potentially leading to session hijacking or defacement. No public exploit or active exploitation has been identified at this time.
Technical ContextAI
The vulnerability is a stored Cross-Site Scripting (XSS) in the Image Hover Effects Block WordPress plugin, which provides custom hover effects for images. The root cause is improper neutralization of user-supplied input during web page generation (CWE-79). The plugin fails to sanitize or escape input before storing it, allowing malicious scripts to be saved and later executed in the context of an administrator's browser. The affected product is identified by the CPE string for the WordPress plugin 'image-hover-effects-block'.
RemediationAI
Update the Image Hover Effects Block plugin to version 1.4.6 or later, which contains the fix. The vendor advisory is available at the Patchstack link. As a workaround, restrict contributor-level access to trusted users only, or disable the plugin if not essential. No other compensating controls are recommended as the patch is straightforward.
