CVE-2025-2364
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 · uneditedA vulnerability classified as problematic was found in lenve VBlog up to 1.0.0. Affected by this vulnerability is the function addNewArticle of the file blogserver/src/main/java/org/sang/service/ArticleService.java. The manipulation of the argument mdContent/htmlContent leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceA stored Cross-Site Scripting (XSS) vulnerability exists in the addNewArticle function of VBlog's ArticleService.java. The application fails to properly sanitize the mdContent and htmlContent parameters before storing and rendering them, allowing remote attackers to inject malicious JavaScript that executes in other users' browsers when viewing articles.

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.
-
Confirm VBlog installation existsCheck for running VBlog application or search for VBlog-related files, WAR, JAR, or deployment directories on the systemAffected if VBlog (Lenve Vblog) is deployed and running in the environment
-
Identify VBlog versionCheck the application metadata (pom.xml, MANIFEST.MF, version info in the application banner, or admin panel) to determine the installed versionAffected if The installed version cannot be determined or is any version of Lenve Vblog (all versions are affected)
-
Verify article creation feature is enabledCheck if the article publishing functionality (addNewArticle function) is accessible to users, typically via the web interface at an endpoint like /article/add or similar, or by inspecting the application's routing configurationAffected if The addNewArticle endpoint/function is exposed and accessible to users or unauthenticated attackers
-
Inspect stored article contentQuery the application's database or examine stored article records for the mdContent and htmlContent fields to see if raw user input is being stored without sanitizationAffected if Articles contain unsanitized content in mdContent or htmlContent fields that include raw HTML, markdown, or script tags
If VBlog is installed and the article creation feature is accessible, the environment is affected because all versions of Lenve Vblog fail to sanitize mdContent and htmlContent parameters, allowing stored XSS.

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 dataImplement output encoding and input sanitization for the mdContent/htmlContent parameters using a well-vetted HTML sanitization library (such as OWASP Java HTML Sanitizer) before storing and rendering content. Validate and escape all user-supplied content at display time.
