Deeper analysis
XWiki Platform, a generic wiki platform for building applications, contains an authorization vulnerability tracked as CVE-2022-41937. The flaw stems from missing access controls that permit any user with view rights to import a specially crafted XAR package and thereby alter arbitrary wiki pages. It is assigned CWE-862 and carries a CVSS 3.1 score of 9.6 reflecting network attack vector, low complexity, and changed scope with high confidentiality and integrity impact.
An attacker who already possesses view access on the affected instance can exploit the issue to achieve unauthorized page modifications across the wiki without further authentication or user interaction. This capability can be used to alter content, inject malicious data, or escalate privileges within the platform.
Official patches are available in XWiki 14.6RC1, 14.6, and 13.10.8. The project advisory recommends restricting view rights on the Filter.WebHome page to main-wiki administrators only, or applying the configuration changes described in commit fb49b4f. The associated EPSS score has remained flat at 0.0973 with no material increase since disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
