# CVE-2025-46554: XWiki missing authorization when accessing the wiki level attachments list and metadata via REST API

- Exploited (CISA KEV): no
- Published: 2025-04-30
- CVSS: 5.3 MEDIUM (v3.1)
- EPSS: 1.1% (65th percentile)
- CWE: CWE-862

XWiki is a generic wiki platform. In versions starting from 1.8.1 to before 14.10.22, from 15.0-rc-1 to before 15.10.12, from 16.0.0-rc-1 to before 16.4.3, and from 16.5.0-rc-1 to before 16.7.0, anyone can access the metadata of any attachment in the wiki using the wiki attachment REST endpoint. There is no filtering for the results depending on current user rights, meaning an unauthenticated user could exploit this even in a private wiki. This issue has been patched in versions 14.10.22, 15.10.12, 16.4.3, and 16.7.0.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
