Vulnerability from github – Published: 2026-04-14 22:34 – Updated: 2026-04-24 20:29

Summary

XWiki's REST APIs can list all pages/spaces, leading to unavailability

Details

Impact

REST API endpoints like /xwiki/rest/wikis/xwiki/spaces/AnnotationCode/pages/AnnotationConfig/objects/AnnotationCode.AnnotationConfig/0/properties list all available pages as part of the metadata for database list properties, which can exhaust available resources on large wikis.

Patches

This problem has been patched by applying the configured query limit also to the available values for database list properties in XWiki 16.10.16, 17.4.8 and 17.10.1.

Workarounds

We're not aware of any workarounds apart from upgrading the affected modules.

CVE-2026-40104 (GCVE-0-2026-40104)

Vulnerability from cvelistv5 – Published: 2026-04-15 00:01 – Updated: 2026-04-16 14:08

Title

XWiki's REST APIs can list all pages/spaces, leading to unavailability

Summary

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.
