CVE-2025-65089 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the xwikisas xwiki-pro-macros product, specifically versions prior to 1.27.0. The issue arises because the Remote Macros component, which facilitates rendering macros useful for migrating content from Confluence, fails to enforce proper authorization checks on the 'view file' macro. This allows a user who does not have view rights on a page to still access and view the content of office attachments embedded in that page. The vulnerability compromises confidentiality by exposing sensitive document content to unauthorized users. The flaw requires that the attacker have at least some privileges (PR:L) and user interaction (UI:R), but no elevated privileges or local access are needed. The vulnerability has a CVSS v3.1 base score of 6.8, indicating a medium severity level, with network attack vector (AV:N), low attack complexity (AC:L), partial privileges required, and scope changed (S:C) due to the breach of access control boundaries. The issue was publicly disclosed on November 19, 2025, and has been patched in version 1.27.0 of the xwiki-pro-macros. No known exploits have been reported in the wild to date. This vulnerability is particularly relevant for organizations that use XWiki for collaborative document management and content migration from Confluence, as it could lead to unauthorized disclosure of sensitive office documents embedded within wiki pages.

For European organizations, the primary impact of CVE-2025-65089 is the unauthorized disclosure of confidential information contained in office attachments within XWiki pages. This can lead to data breaches involving sensitive corporate, governmental, or personal data, potentially violating GDPR and other data protection regulations. The exposure of confidential documents can undermine trust, cause reputational damage, and result in regulatory fines. Since the vulnerability does not affect data integrity or availability, the risk is focused on confidentiality loss. Organizations relying on XWiki for internal knowledge bases, document collaboration, or content migration from Confluence are at risk if they run vulnerable versions. Attackers with low privileges and network access could exploit this vulnerability to gain unauthorized read access, which may facilitate further social engineering or targeted attacks. The lack of known exploits suggests limited active threat currently, but the presence of a public patch means attackers could develop exploits if systems remain unpatched.

The most effective mitigation is to upgrade xwiki-pro-macros to version 1.27.0 or later, where the authorization checks have been properly implemented. Organizations should audit their XWiki deployments to identify any instances running vulnerable versions and prioritize patching. Additionally, review and tighten access control policies on wiki content, especially for pages containing sensitive office attachments. Implement monitoring and alerting for unusual access patterns to wiki pages or attachments. Restrict user privileges to the minimum necessary to reduce the risk of unauthorized access. If immediate patching is not possible, consider disabling the 'view file' macro or restricting its use to trusted users only. Regularly review and update security policies related to collaborative platforms and educate users about the risks of unauthorized data exposure. Finally, maintain an inventory of software components and track vulnerability disclosures to ensure timely response.
