How severe is GHSA-xxp2-9c9g-7wmj?

GHSA-xxp2-9c9g-7wmj has a CVSS score of 9.9/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by GHSA-xxp2-9c9g-7wmj?

GHSA-xxp2-9c9g-7wmj affects the following packages: org.xwiki.platform:xwiki-platform-localization-source-wiki (Maven), org.xwiki.platform:xwiki-platform-localization-source-wiki (Maven), org.xwiki.platform:xwiki-platform-localization-source-wiki (Maven). Ecosystems affected: Maven.

How do I fix GHSA-xxp2-9c9g-7wmj?

Update org.xwiki.platform:xwiki-platform-localization-source-wiki to 14.10.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xxp2-9c9g-7wmj is resolved across your whole dependency graph.

How do I detect GHSA-xxp2-9c9g-7wmj 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-localization-source-wiki, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-xxp2-9c9g-7wmj if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is GHSA-xxp2-9c9g-7wmj actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-xxp2-9c9g-7wmj, 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 GHSA-xxp2-9c9g-7wmj?

GHSA-xxp2-9c9g-7wmj has an EPSS (Exploit Prediction Scoring System) score of 1.4%, placing it in the 73th 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.

What type of vulnerability is GHSA-xxp2-9c9g-7wmj?

GHSA-xxp2-9c9g-7wmj is classified as CWE-862 (CWE-862). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-xxp2-9c9g-7wmj published, and has it been updated?

GHSA-xxp2-9c9g-7wmj was published on April 10, 2024 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

In multilingual wikis, translations can be edited by any user who has edit right, circumventing the rights that are normally required for authoring translations (script right for user-scope translations, wiki admin for translations on the wiki). This can be exploited for remote code execution if the translation value is not properly escaped where it is used. To reproduce, in a multilingual wiki, as a user without script or admin right, edit a translation of AppWithinMinutes.Translations and in the line platform.appwithinminutes.description= add {{async}}{{groovy}}println("Hello from Translation"){{/groovy}}{{/async}} at the end. Then open the app with in minutes home page (AppWithinMinutes.WebHome) in the same locale. If translations are still working and "Hello from Translation" is displayed at the end of the introduction, the installation is vulnerable.

Patches

This has been patched in XWiki 14.10.20, 15.5.4 and 15.10RC1.

Workarounds

We're not aware of any workaround except restricting edit right on documents that contain translations.
