Which packages are affected by CVE-2023-37910?

CVE-2023-37910 affects the following packages: org.xwiki.platform:xwiki-platform-attachment-api (Maven), org.xwiki.platform:xwiki-platform-attachment-api (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-37910?

Update org.xwiki.platform:xwiki-platform-attachment-api to 14.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-37910 is resolved across your whole dependency graph.

How do I detect CVE-2023-37910 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-attachment-api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-37910 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-2023-37910 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-37910, including 1 in-the-wild exploitation 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 CVE-2023-37910?

CVE-2023-37910 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 54th 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.

Description

Impact

An attacker with edit access on any document (can be the user profile which is editable by default) can move any attachment of any other document to this attacker-controlled document. This allows the attacker to access and possibly publish any attachment of which the name is known, regardless if the attacker has view or edit rights on the source document of this attachment. Further, the attachment is deleted from the source document. This vulnerability exists since the introduction of attachment move support in XWiki 14.0 RC1.

Patches

This vulnerability has been patched in XWiki 14.4.8, 14.10.4, and 15.0 RC1.

Workarounds

There is no workaround apart from upgrading to a fixed version.
