Summary
XWiki Platform allows users with edit rights to modify all pages in the `CKEditor` space, which can lead to the removal of technical documents and editing the JavaScript configuration of CKEditor, resulting in persistent XSS.
Risk Assessment
The organization may lose access to important documents and be exposed to XSS attacks, which can lead to data theft or takeover of applications.
Recommendation
It is recommended to upgrade to XWiki version 14.10.6 or 15.1 and CKEditor Integration extension 1.64.9. Users unable to upgrade should restrict edit and delete rights to trusted users or groups.

- CVE-2026-53921Critical
In odhcpd (the DHCPv6/DHCPv4/RA server used by OpenWrt) prior to version 25.12, the DHCPv6 IA response handler writes past a fixed 512-byte stack buffer (pdbuf) when a single DHCPv6 REQUEST carries enough IA options to nearly exhaust the reply space. Two independent overflow sites exist in the same call chain, both reachable over the network via a single unauthenticated UDP packet. odhcpd runs as root on OpenWrt, and embedded targets often lack stack canaries and ASLR, making code execution realistic.

In DJI CrystalSky ZS600C firmware v0.3.9.7 through v0.6.6.9, the Android Debug Bridge daemon (adbd) lacks authentication for a critical function. The device ships with ro.adb.secure=0 and USB ADB enabled by default; once ADB over TCP is enabled, the same unauthenticated shell (uid 2000) is reachable over the network. This provides a foothold for privilege escalation to root.

In PraisonAI from version 4.2.1 to before 4.6.59, the AgentOS FastAPI deployment surface remains unauthenticated despite the earlier fix for CVE-2026-40151. The chat route directly calls agent.chat(request.message), and both no-auth and wrong-bearer requests execute the deployed agent.

Original NVD description (English source)
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with edit rights can edit all pages in the `CKEditor' space. This makes it possible to perform a variety of harmful actions, such as removing technical documents, leading to loss of service and editing the javascript configuration of CKEditor, leading to persistent XSS. This issue has been patched in XWiki 14.10.6 and XWiki 15.1. This issue has been patched on the CKEditor Integration extension 1.64.9 for XWiki version older than 14.6RC1. Users are advised to upgrade. Users unable to upgrade may manually address the issue by restricting the `edit` and `delete` rights to a trusted user or group (e.g. the `XWiki.XWikiAdminGroup` group), implicitly disabling those rights for all other users. See commit `9d9d86179` for details.
