Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Team Heateor Fancy Comments WordPress allows Stored XSS.This issue affects Fancy Comments WordPress: from n/a through 1.2.14.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A stored Cross-Site Scripting (XSS) vulnerability exists in the Team Heateor Fancy Comments WordPress plugin. The plugin fails to properly sanitize user input submitted through comment fields, allowing malicious JavaScript code to be persistently stored and executed in the browsers of users who view affected comments.

MitigationUpdate the Fancy Comments plugin to the latest version which should include proper input sanitization and output encoding. If no patched version is available, implement context-aware output encoding on all user-generated content before rendering.
