CVE-2022-4207
Medium 5.5
In plain English
A medium-severity security flaw in Image Hover Effects Ultimate (Image Gallery, Effects, Lightbox, Comparison or Magnifier) from biplob018. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.6% (higher than 47% of all known vulnerabilities).
Official description
The Image Hover Effects Ultimate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several values that can be added to an Image Hover in versions 9.8.1 to 9.8.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, the plugin only allows administrators access to edit Image Hovers, however, if a site admin makes the plugin's features available to lower privileged users through the 'Who Can Edit?' setting then this can be exploited by those users.
