How severe is GHSA-wvqx-m5px-6cmp?

No CVSS score has been assigned to GHSA-wvqx-m5px-6cmp yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-wvqx-m5px-6cmp?

GHSA-wvqx-m5px-6cmp affects the following packages: org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-platform-web-templates (Maven). Ecosystems affected: Maven.

How do I fix GHSA-wvqx-m5px-6cmp?

Update org.xwiki.platform:xwiki-platform-web-templates to 16.10.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wvqx-m5px-6cmp is resolved across your whole dependency graph.

How do I detect GHSA-wvqx-m5px-6cmp 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-web-templates, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-wvqx-m5px-6cmp if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-wvqx-m5px-6cmp actively exploited in the wild?

No public exploit code has been indexed for GHSA-wvqx-m5px-6cmp yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-wvqx-m5px-6cmp?

GHSA-wvqx-m5px-6cmp has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 44th 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-wvqx-m5px-6cmp?

GHSA-wvqx-m5px-6cmp is classified as Cross-site Scripting (XSS) (CWE-79), CWE-80 (CWE-80). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for GHSA-wvqx-m5px-6cmp?

A Nuclei detection template exists for GHSA-wvqx-m5px-6cmp, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-wvqx-m5px-6cmp published, and has it been updated?

GHSA-wvqx-m5px-6cmp was published on January 23, 2026 and was last updated on February 3, 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

A reflected cross site scripting (XSS) vulnerability in XWiki allows an attacker to execute arbitrary actions in XWiki with the rights of the victim if the attacker manages to trick a victim into visiting a crafted URL. If the victim has administrative or programming rights, those rights can be exploited to gain full access to the XWiki installation.

Patches

This vulnerability has been patched in XWiki 17.8.0RC1, 17.4.5 and 16.10.12.

Workarounds

The patch can be applied manually, only a single line in templates/logging_macros.vm needs to be changed, no restart is required.
