GHSA-v662-xpcc-9xf6
GHSA-v662-xpcc-9xf6 is a CWE-281 vulnerability in org.xwiki.platform:xwiki-platform-rendering-wikimacro-store. O3 Security confirms whether GHSA-v662-xpcc-9xf6 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
It's possible to execute anything with the rights of the author of a macro which uses the {{wikimacrocontent}} macro

This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The {{wikimacrocontent}} executes the content with the rights of the wiki macro author instead of the caller of that wiki macro. This makes possible to inject scripts through it and they will be executed with the rights of the wiki macro (very often a user which has Programming rights).
Fortunately, no such macro exists by default in XWiki Standard but one could have been created or installed with an extension.
Patches
It has been patched in versions XWiki 12.6.3, 11.10.11 and 12.8-rc-1.
Workarounds
There is no easy workaround other than disabling the affected macros. Inserting content in a safe way or knowing what is the user who called the wiki macro is not easy.

Detection & 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-rendering-wikimacro-store. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.xwiki.platform:xwiki-platform-rendering-wikimacro-store to 11.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v662-xpcc-9xf6 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.
How O3 protects you
O3 pinpoints whether GHSA-v662-xpcc-9xf6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-v662-xpcc-9xf6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-v662-xpcc-9xf6 in your dependencies?
O3 detects GHSA-v662-xpcc-9xf6 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
