This critical-severity CVE scores 9.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 96% of all CVEs by exploit prediction. 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

There are multiple issues.

  • Updates to the XAPI database sanitise input strings, but try
generating the notification using the unsanitised input. This causes the database's event thread to terminate and cease further processing.
  • XAPI's UTF-8 encoder implements v3.0 of the Unicode spec, but XAPI
uses libraries which conform to the stricter v3.1 of the Unicode spec. This causes some strings to be accepted as valid UTF-8 by XAPI, but rejected by other libraries in use. Notably, such strings can be entered into the database, after which the database can no longer be loaded.
  • There is no input sanitisation for Map/Set updates on objects in the
XAPI database.
