Updates to the XAPI database sanitise input strings, but try\n    generating the notification using the unsanitised input.  This\n    causes the database's event thread to terminate and cease further\n    processing.\n\n 2. XAPI's UTF-8 encoder implements v3.0 of the Unicode spec, but XAPI\n    uses libraries which conform to the stricter v3.1 of the Unicode\n    spec.  This causes some strings to be accepted as valid UTF-8 by\n    XAPI, but rejected by other libraries in use.  Notably, such strings\n    can be entered into the database, after which the database can no\n    longer be loaded.\n\n 3. There is no input sanitisation for Map/Set updates on objects in the\n    XAPI database.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":null,"cwes":["CWE-20"],"references":["https://xenbits.xen.org/xsa/advisory-474.html","http://www.openwall.com/lists/oss-security/2025/09/09/3","http://xenbits.xen.org/xsa/advisory-474.html"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2025-58146","score":0.00178,"percentile":0.07387,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
