How severe is GHSA-xwph-x6xj-wggv?

GHSA-xwph-x6xj-wggv has a CVSS score of 4.7/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-xwph-x6xj-wggv?

GHSA-xwph-x6xj-wggv affects the following packages: org.xwiki.platform:xwiki-platform-oldcore (Maven), org.xwiki.platform:xwiki-platform-oldcore (Maven), org.xwiki.platform:xwiki-platform-oldcore (Maven). Ecosystems affected: Maven.

How do I fix GHSA-xwph-x6xj-wggv?

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.

How do I detect GHSA-xwph-x6xj-wggv 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-oldcore, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-xwph-x6xj-wggv if there is no patch (or I can't update yet)?

Stop reflecting attacker-controlled destinations: resolve every redirect target against an allowlist of paths or hosts you own, prefer a server-side key over a full URL in the request, and reject absolute URLs entirely where the flow only ever needs a relative one.

Is GHSA-xwph-x6xj-wggv actively exploited in the wild?

Yes. There are 3 known exploit references for GHSA-xwph-x6xj-wggv, including 3 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-xwph-x6xj-wggv?

GHSA-xwph-x6xj-wggv has an EPSS (Exploit Prediction Scoring System) score of 1.8%, 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-xwph-x6xj-wggv?

GHSA-xwph-x6xj-wggv is classified as Open Redirect (CWE-601). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Is there exploit tooling available for GHSA-xwph-x6xj-wggv?

A Nuclei detection template exists for GHSA-xwph-x6xj-wggv, 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-xwph-x6xj-wggv published, and has it been updated?

GHSA-xwph-x6xj-wggv 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.
