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
Cross-site scripting vulnerability exists in a-blog cms Ver.3.1.x series versions prior to Ver.3.1.12, Ver.3.0.x series versions prior to Ver.3.0.32, Ver.2.11.x series versions prior to Ver.2.11.61, Ver.2.10.x series versions prior to Ver.2.10.53, and Ver.2.9 and earlier versions. If this vulnerability is exploited, a user with a contributor or higher privilege who can log in to the product may execute an arbitrary script on the web browser of the user who accessed the website using the product.

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

Cross-site scripting (XSS) vulnerability in a-blog CMS allows authenticated users with contributor-level or higher privileges to inject malicious JavaScript that executes in the browsers of other users accessing the website. The vulnerability affects multiple version branches (3.1.x, 3.0.x, 2.11.x, 2.10.x, and 2.9 and earlier) prior to their respective patched releases.

MitigationUpdate a-blog CMS to the fixed versions (3.1.12, 3.0.32, 2.11.61, or 2.10.53) as appropriate for your branch. Additionally, audit privileged user accounts and implement output encoding as a defense-in-depth measure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed a-blog CMS version
    Locate the version information in your a-blog CMS installation, typically found in the admin dashboard under System Settings > Version Info, or by checking a version file in the installation directory if one exists
    Affected if The installed version falls within any of these ranges: < 2.10.53; >= 2.11.0 and < 2.11.61; >= 3.0.0 and < 3.0.32; or >= 3.1.0 and < 3.1.12
  2. Verify user role configuration
    Access the user management or role management section of the admin panel and review the defined user roles and their permission levels
    Affected if The system has user roles with contributor-level or higher privileges enabled, which is the default configuration for this CMS
  3. Check for existing contributor-level accounts
    Review the list of registered users in the admin panel under User Management to identify accounts assigned contributor, editor, or administrator roles
    Affected if Any user accounts with contributor-level or higher privileges exist in the system
  4. Inspect input handling for user-generated content
    Examine the CMS configuration files and template settings related to blog post creation, comment submission, or other user input features to confirm they are enabled
    Affected if Features that allow contributor-level users to create or edit content are active (these are standard CMS features and typically enabled by default)

You are affected if your a-blog CMS version is within the vulnerable ranges AND you have users with contributor-level or higher privileges enabled, as the XSS payload would be injected through content creation features accessible to those users.

Upgrade available Upgrade to 2.10.53 / 2.11.61 / 3.0.32 or later
Fixed in 2.10.532.11.613.0.32
Interim mitigation

Update a-blog CMS to the fixed versions (3.1.12, 3.0.32, 2.11.61, or 2.10.53) as appropriate for your branch. Additionally, audit privileged user accounts and implement output encoding as a defense-in-depth measure.

Recommended fix High confidence

Upgrade to Ver.3.1.12, Ver.3.0.32, Ver.2.11.61, or Ver.2.10.53 (or later versions if available)

  1. 1. Create a full backup of the current a-blog cms installation including database and files
  2. 2. Download the appropriate fixed version from the official a-blog cms website (developer.a-blogcms.jp) or update source
  3. 3. If using the built-in update function, navigate to the admin panel and run the update check to apply the patch
  4. 4. If manual update: upload the new version files, overwriting existing files while preserving config files and custom themes
  5. 5. Verify the update was successful by checking the version number in the admin panel
  6. 6. Test that the application functions correctly, particularly areas where contributor-level users input content
  7. 7. Clear any application caches if the CMS uses caching
Caveat Patch updates within the same minor version branch typically have minimal breaking changes; always test in staging first
