This critical-severity CVE scores 9.9 under NVD CVSS v3. EPSS exploit probability: 1.2% (66th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

XWiki Commons are technical libraries common to several other top level XWiki projects. Starting in version 3.1-milestone-1, any user can edit their own profile and inject code, which is going to be executed with programming right. The same vulnerability can also be exploited in all other places where short text properties are displayed, e.g., in apps created using Apps Within Minutes that use a short text field. The problem has been patched on versions 13.10.9, 14.4.4, 14.7RC1.
