CVE-2025-49586
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedXWiki is an open-source wiki software platform. Any XWiki user with edit right on at least one App Within Minutes application (the default for all users XWiki) can obtain programming right/perform remote code execution by editing the application. This vulnerability has been fixed in XWiki 17.0.0, 16.4.7, and 16.10.3.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisAn authorization check exists but is flawed, so it passes when it should fail. Attackers probe roles and object references to find the gap. Remediation means centralising and correctly implementing the access-control logic, then testing it against every role.
