EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

GHSA-xwph-x6xj-wggv plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Impact

It is possible to bypass the existing security measures put in place to avoid open redirect by using a redirect such as //mydomain.com (i.e. omitting the http:). It was also possible to bypass it when using URL such as http:/mydomain.com.

Patches

The problem has been patched on XWiki 13.10.10, 14.4.4 and 14.8RC1.

Workarounds

The only way to workaround the bug is by providing a patched jar of xwiki-platform-oldcore containing the following changes: https://github.com/xwiki/xwiki-platform/commit/e4f7f68e93cb08c25632c126356d218abf192d1e#diff-c445f288d5d63424f56ef13f65514ab4e174a72e979b53b88197c2b7def267cf.

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update org.xwiki.platform:xwiki-platform-oldcore to 13.10.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xwph-x6xj-wggv is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-xwph-x6xj-wggv can be triaged on real exposure rather than presence alone.

Tailored to GHSA-xwph-x6xj-wggv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
