|---|---|---|
| concrete5/concrete5 | ≥ 9.0.0RC1, < 9.2.8< 8.5.16 | 9.2.88.5.16 |

Concrete CMS version 9 before 9.2.8 and previous versions before 8.5.16 are vulnerable to Stored XSS in the Custom Class page editing. Prior to the fix, a rogue administrator could insert malicious code in the custom class field due to insufficient validation of administrator provided data. The Concrete CMS security team gave this vulnerability a CVSS v3.1 score of 3.1 with a vector of AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:L https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator . Thanks Alexey Solovyev for reporting.
