How severe is GHSA-jjm5-5v9v-7hx2?

GHSA-jjm5-5v9v-7hx2 has a CVSS score of 5.4/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

How do I fix GHSA-jjm5-5v9v-7hx2?

Update org.xwiki.platform:xwiki-platform-security-authentication-default to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jjm5-5v9v-7hx2 is resolved across your whole dependency graph.

How do I mitigate GHSA-jjm5-5v9v-7hx2 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-jjm5-5v9v-7hx2 actively exploited in the wild?

Yes. There are 2 known exploit references for GHSA-jjm5-5v9v-7hx2, including 2 in-the-wild exploitations 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-jjm5-5v9v-7hx2?

GHSA-jjm5-5v9v-7hx2 has an EPSS (Exploit Prediction Scoring System) score of 1.7%, placing it in the 78th 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-jjm5-5v9v-7hx2?

GHSA-jjm5-5v9v-7hx2 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type 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-jjm5-5v9v-7hx2?

A Nuclei detection template exists for GHSA-jjm5-5v9v-7hx2, 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-jjm5-5v9v-7hx2 published, and has it been updated?

GHSA-jjm5-5v9v-7hx2 was published on April 12, 2023 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Detection & mitigation playbook

Open-source dependency

Detect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-security-authentication-default, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-security-authentication-default to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jjm5-5v9v-7hx2 is resolved across your whole dependency graph.
Workarounds
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.

How to detect GHSA-jjm5-5v9v-7hx2

A community-maintained Nuclei template exists for this CVE. You can scan for it directly:

nuclei -id ghsa-jjm5-5v9v-7hx2 -u https://target

Template: XWiki >= 13.10.8 - Cross-Site Scripting
Severity: medium
Impact: Successful exploitation could allow an attacker to execute malicious scripts in the context of the victim's browser.
Remediation: Implement proper input validation and output encoding to prevent XSS attacks in the XWiki application.
