Description
Impact
Any user with edit right on a page of the wiki can create an XClass with a database list property that references a password property, for example the password hash that is stored for users. When adding an object of that XClass, the content of that password property is displayed. In practice, with a standard rights setup, this means that any user with an account on the wiki can access password hashes of all users, and possibly other password properties (with hashed or plain storage) that are on pages that the user can view.
Patches
This vulnerability has been pached in XWiki 16.4.7, 16.10.5, and 17.2.0 by disallowing the use of password properties in database list properties. Additionally, queries for email properties are disallowed, too, when email obfuscation is enabled.
Workarounds
We're not aware of any workarounds.

xwikixwikiDetection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-oldcore, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-oldcore to 16.4.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r38m-cgpg-qj69 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
