AI Analysis
Technical Summary
CVE-2025-12379 is a stored cross-site scripting vulnerability in the averta Shortcodes and extra features for Phlox theme WordPress plugin. It affects all versions up to and including 2.17.13 due to improper neutralization of input during web page generation, specifically involving the 'tag' and 'title_tag' parameters.

Potential Impact
Successful exploitation allows an authenticated user with Contributor-level access or above to inject persistent malicious scripts into pages generated by the plugin.
