Prior to version 0.31.0.0, the application fails to properly sanitize user-controlled input when creating or editing blog posts. An attacker can inject a malicious JavaScript payload into blog post content, which is then stored server-side. This stored payload is later rendered unsafely in multiple application views without proper output encoding, leading to stored cross-site scripting (XSS). This issue has been patched in version 0.31.0.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","score":9.0},"cwes":["CWE-79"],"references":["https://github.com/ci4-cms-erp/ci4ms/releases/tag/0.31.0.0","https://github.com/ci4-cms-erp/ci4ms/security/advisories/GHSA-x7wh-g25g-53vg","https://github.com/ci4-cms-erp/ci4ms/security/advisories/GHSA-x7wh-g25g-53vg"],"products":["ci4-cms-erp:ci4ms"],"source":"nvd","synced_at":"2026-10-26T00:31:35.753532240+00:00"},"epss":{"cve":"CVE-2026-34568","score":0.00317,"percentile":0.24437,"date":"2026-10-25"},"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).
