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 Platform is a generic wiki platform. Starting in 4.5-rc-1 and prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, the search administration interface doesn't properly escape the id and label of search user interface extensions, allowing the injection of XWiki syntax containing script macros including Groovy macros that allow remote code execution, impacting the confidentiality, integrity and availability of the whole XWiki instance. This attack can be executed by any user who can edit some wiki page like the user's profile (editable by default) as user interface extensions that will be displayed in the search administration can be added on any document by any user. The necessary escaping has been added in XWiki 14.10.15, 15.5.2 and 15.7RC1. As a workaround, the patch can be applied manually applied to the page `XWiki.SearchAdmin`.

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.

How this class of weakness works · CWE-94

The application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Recommended fix High confidence

XWiki 14.10.15+ (for 14.10.x branch) or XWiki 15.10+ (latest stable, for 15.x branch)

  1. 1. Back up your XWiki database and configuration files before upgrading.
  2. 2. Identify your current XWiki version from the affected list (14.10.x, 15.0-15.4.x, 15.6, or 15.7).
  3. 3. For XWiki 14.10.x (versions >= 4.5, < 14.10.5): Upgrade to XWiki 14.10.15 or later (recommended: latest 14.10.x stable).
  4. 4. For XWiki 15.0-15.4.x (versions >= 15.0, < 15.5.2): Upgrade to XWiki 15.5.2 or later (recommended: latest 15.x stable).
  5. 5. For XWiki 15.6: Upgrade to XWiki 15.7RC1 or later (recommended: latest 15.x stable).
  6. 6. For XWiki 15.7: Upgrade to the latest available XWiki 15.x stable release (e.g., 15.10.x or newer).
  7. 7. After upgrading, verify the search administration interface works correctly and test that the patch is applied.
  8. 8. As an alternative manual workaround, edit the page `XWiki.SearchAdmin` and apply proper escaping to the id and label fields of search user interface extensions to prevent XWiki syntax injection.
Caveat Standard upgrade risks apply - review release notes for your target version for any configuration or compatibility changes
