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
XWiki Remote Macros provides XWiki rendering macros that are useful when migrating content from Confluence. Starting in version 1.0 and prior to version 1.26.5, missing escaping of the classes parameter in the panel macro allows remote code execution for any user who can edit any page The classes parameter is used without escaping in XWiki syntax, thus allowing XWiki syntax injection which enables remote code execution. Version 1.26.5 contains a patch for the issue.

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 confidence

The XWiki Remote Macros plugin versions 1.0 through 1.26.4 fail to properly escape the 'classes' parameter in the panel macro. This parameter is used directly in XWiki syntax without sanitization, enabling an authenticated attacker with page edit permissions to inject malicious XWiki syntax and achieve remote code execution on the server.

MitigationUpgrade XWiki Remote Macros to version 1.26.5 or later which contains the patch for proper parameter escaping. If immediate upgrading is not possible, restrict page edit permissions to trusted users only.

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. Verify XWiki Remote Macros plugin is installed
    Check your XWiki installation for the presence of the Remote Macros plugin. This is typically done through the XWiki administration interface under installed extensions, or by searching for the plugin package in your installation directories.
    Affected if The Remote Macros plugin is found installed in the XWiki instance
  2. Determine the installed version of XWiki Remote Macros
    Locate the version information for the Remote Macros plugin through the XWiki extension manager, the plugin's JAR file metadata, or the extension descriptor. Compare this version against the affected range.
    Affected if The installed version is 1.0 through 1.26.4 inclusive
  3. Identify use of the panel macro with the classes parameter
    Search XWiki pages and content for usage of the panel macro that includes the 'classes' parameter. This can be done by searching wiki content for patterns like '((panel' or 'panel)' combined with 'classes='.
    Affected if The panel macro is used with the 'classes' parameter in any wiki page
  4. Verify edit permissions on wiki pages
    Check the permission configuration for the wiki to determine which users or groups have page edit or macro execution rights, particularly for pages using the vulnerable panel macro with the classes parameter.
    Affected if Users other than trusted administrators have edit permissions on pages containing the vulnerable macro usage

The environment is affected if the XWiki Remote Macros plugin versions 1.0 through 1.26.4 are installed and the panel macro is used with the classes parameter on pages accessible to users with edit permissions.
