Which packages are affected by CVE-2022-24821?

CVE-2022-24821 affects the following packages: org.xwiki.platform:xwiki-platform-skin-skinx (Maven), org.xwiki.platform:xwiki-platform-skin-skinx (Maven), org.xwiki.platform:xwiki-platform-skin-skinx (Maven). Ecosystems affected: Maven.

How do I fix CVE-2022-24821?

Update org.xwiki.platform:xwiki-platform-skin-skinx to 13.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-24821 is resolved across your whole dependency graph.

How do I detect CVE-2022-24821 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-skin-skinx, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2022-24821 if there is no patch (or I can't update yet)?

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.

Is CVE-2022-24821 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2022-24821, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2022-24821?

CVE-2022-24821 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 57th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Description

Impact

Simple users can create global SSX/JSX without specific rights: in theory only users with Programming Rights should be allowed to create SSX or JSX that are executed everywhere on a wiki. But a bug allow anyone with edit rights to actually create those.

Patches

This issue has been patched in XWiki 13.10-rc-1, 12.10.11 and 13.4.6.

Workarounds

There's no easy workaround for this issue, administrators should upgrade their wiki.
