CVE-2022-29413
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 · uneditedCross-Site Request Forgery (CSRF) leading to Stored Cross-Site Scripting (XSS) in Mufeng's Hermit 音乐播放器 plugin <= 3.1.6 on WordPress via &title parameter.
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 · high confidenceThe Hermit 音乐播放器 WordPress plugin versions 3.1.6 and below is vulnerable to Cross-Site Request Forgery (CSRF) that enables Stored Cross-Site Scripting (XSS). Attackers can trick authenticated administrators into clicking malicious links, causing the browser to send crafted requests that inject malicious JavaScript via the &title parameter, which is then stored and executed when other users view the affected content.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Hermit plugin installationLog into WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'Hermit 音乐播放器' or 'Hermit' in the plugin list.Affected if The plugin is not installed or is not present in the WordPress installation.
-
Identify installed Hermit versionIn the WordPress admin, find the Hermit plugin entry in the Plugins list. The version number is displayed below the plugin name. Alternatively, inspect the file /wp-content/plugins/hermit/class.php or the main plugin header file and locate the 'Version:' comment.Affected if The installed version is 3.1.6 or lower.
-
Check if playlist or playlist item creation is accessibleNavigate to the Hermit plugin settings or playlist management section in WordPress admin. Look for options to create or edit playlists where the title parameter would be used.Affected if The plugin allows creating or editing playlists/playlist items where a title field is present.
-
Inspect title parameter handling for lack of sanitizationIf you have code access, examine the PHP file that handles playlist title input (typically in the plugin admin panel or shortcode handler). Look for functions like sanitize_text_field, esc_html, or wp_kses applied to the title parameter.Affected if The code does not sanitize or escape the title parameter before storage or output, or no anti-CSRF nonce verification is present in the form handling.
You are affected if the Hermit plugin is installed with version 3.1.6 or lower and playlist title editing functionality is accessible without proper CSRF protection and input sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the Hermit 音乐播放器 plugin to the latest patched version. Additionally, implement anti-CSRF tokens (nonces) for state-changing operations and ensure all user-supplied input, especially the title parameter, is properly sanitized and escaped before storage and output.
