CVE-2026-40104: CWE-770: Allocation of Resources Without Limits or Throttling in xwiki org.xwiki.platform:xwiki-platform-oldcore
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Versions 1.8-rc-1, 17.0.0-rc-1 and 17.5.0-rc-1 and prior include a resource exhaustion vulnerability in REST API endpoints such as /xwiki/rest/wikis/xwiki/spaces/AnnotationCode/pages/AnnotationConfig/objects/AnnotationCode.AnnotationConfig/0/properties, which list all available pages as part of the metadata for database list properties without applying query limits. On large wikis, this can exhaust available server resources. This issue has been patched in versions 16.10.16, 17.4.8 and 17.10.1.
AI Analysis
Technical Summary
The XWiki Platform versions 1.8-rc-1 through versions before 16.10.16, 17.0.0-rc-1 through before 17.4.8, and 17.5.0-rc-1 through before 17.10.1 contain a resource exhaustion vulnerability (CWE-770) in REST API endpoints such as /xwiki/rest/wikis/xwiki/spaces/AnnotationCode/pages/AnnotationConfig/objects/AnnotationCode.AnnotationConfig/0/properties. These endpoints list all available pages as part of metadata for database list properties without enforcing query limits, which can cause excessive consumption of server resources on large wikis. The vulnerability is addressed by patches released in versions 16.10.16, 17.4.8, and 17.10.1.
Potential Impact
Exploitation of this vulnerability can lead to exhaustion of server resources due to unbounded queries in the REST API, potentially causing denial of service conditions on affected XWiki Platform instances. There are no reports of known exploits in the wild. The impact is rated medium with a CVSS 4.0 score of 6.9, reflecting a network attack vector with no privileges or user interaction required and limited impact on availability.
Mitigation Recommendations
This vulnerability has been patched in XWiki Platform versions 16.10.16, 17.4.8, and 17.10.1. Users should upgrade to one of these versions or later to remediate the issue. Since this is not a cloud service, remediation requires applying the official patches. Patch status is confirmed by the vendor advisory information. No additional mitigation steps are indicated.
