CVE-2025-46554 affects the following packages: org.xwiki.platform:xwiki-platform-rest-server (Maven), org.xwiki.platform:xwiki-platform-rest-server (Maven), org.xwiki.platform:xwiki-platform-rest-server (Maven), org.xwiki.platform:xwiki-platform-rest-server (Maven). Ecosystems affected: Maven.

How do I fix CVE-2025-46554?

Update org.xwiki.platform:xwiki-platform-rest-server to 14.10.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-46554 is resolved across your whole dependency graph.

How do I detect CVE-2025-46554 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-rest-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-46554 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 CVE-2025-46554 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-46554 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 CVE-2025-46554?

CVE-2025-46554 has an EPSS (Exploit Prediction Scoring System) score of 1.1%, placing it in the 65th 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 CVE-2025-46554?

CVE-2025-46554 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.

Is there exploit tooling available for CVE-2025-46554?

A Nuclei detection template exists for CVE-2025-46554, 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 CVE-2025-46554 published, and has it been updated?

CVE-2025-46554 was published on April 30, 2025 and was last updated on October 28, 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

Anyone can access the metadata of any attachment in the wiki using the wiki attachment REST endpoint. It's not filtering the result depending on current user rights, a not authenticated user could exploit this even in a totally private wiki.

To reproduce:

remove view from guest on the whole wiki
logout
access http://127.0.0.1:8080/xwiki/rest/wikis/xwiki/spaces/Sandbox/pages/WebHome/attachments

You get a list of attachments, while the expected result should be an empty list.

Patches

This vulnerability has been fixed in XWiki 14.10.22, 15.10.12, 16.7.0-rc-1 and 16.4.3.

Workarounds

We're not aware of any workaround except upgrading.
