GHSA-pvmm-55r5-g3mm · Severity: medium · Ecosystem: maven — XWiki Platform document history including authors of any page exposed to unauthorized actors
XWiki Platform is a generic wiki platform. The REST API exposes the history of any page in XWiki of which the attacker knows the name. The exposed information includes for each modification of the page the time of the modification, the version number, the author of the modification (both username and displayed name) and the version comment. This information is exposed regardless of the rights setup, and even when the wiki is configured to be fully private. On a private wiki, this can be tested by accessing /xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome/history, if this shows the history of the main page then the installation is vulnerable. This has been patched in XWiki 15.10.9 and XWiki 16.3.0RC1.
Conclusion & alert: CVE-2024-45591 is rated High Exploit Risk (72.7/100): CVSS Medium severity, with high exploitation likelihood (EPSS 86.19%, 99th percentile). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +1.75% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
