What I will deliver

• Well-structured HTML article (headings, paragraphs, lists) ready for WordPress editor.
• Tone: concise, authoritative, and practical — reflecting a Hong Kong security expert perspective.
• All references to third-party WordPress security vendors will be removed (no vendor recommendations included).
• Include the vulnerability summary table above at the top of the post.

Options you can specify

When you paste your blog, indicate any of the following preferences:

• Desired post title (otherwise I will extract or create one).
• Include a short summary/excerpt (1–2 sentences).
• Any headings you want emphasized or removed.
• Whether to include code blocks or configuration snippets (I will use <pre><code> for those).
• Image URLs to embed (I will insert <img> tags with alt text if provided).

Example: short converted excerpt

Below is a brief example of the style and format I will use once you supply the blog content.

概述

The Video Onclick plugin was found to contain a reflected Cross-Site Scripting (XSS) vulnerability (CVE-2026-1608). The issue allows an attacker to inject arbitrary script in specific contexts where plugin inputs are not properly sanitized. The overall urgency is low, but administrators should assess exposure on public-facing pages.

技術細節

The flaw occurs when user-supplied input is embedded into output without adequate encoding. Exploitation requires an attacker to craft a link or input that is rendered in a vulnerable template. Successful exploitation could lead to session theft or execution of actions in the context of an authenticated user.

Mitigation notes

Review the plugin output paths and ensure proper input validation and HTML encoding. Prioritize fixes for instances exposed to unauthenticated users or editors with elevated privileges.
