The Snowboard framework in versions 1.1.8, 1.1.9, and 1.2.0 is vulnerable to prototype pollution in the main Snowboard class as well as its plugin loader. The 1.0 branch of Winter is not affected, as it does not contain the Snowboard framework. This issue has been patched in v1.1.10 and v1.2.1. As a workaround, one may avoid this issue by following some common security practices for JavaScript, including implementing a content security policy and auditing scripts.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-1321"],"references":["https://github.com/wintercms/winter/commit/2a13faf99972e84c9661258f16c4750fa99d29a1","https://github.com/wintercms/winter/commit/bce4b59584abf961e9400af3d7a4fd7638e26c7f","https://github.com/wintercms/winter/releases/tag/v1.1.10","https://github.com/wintercms/winter/releases/tag/v1.2.1","https://github.com/wintercms/winter/security/advisories/GHSA-3fh5-q6fg-w28q"],"products":["wintercms:winter"],"source":"nvd","synced_at":"2026-10-19T21:37:08.729216836+00:00"},"epss":{"cve":"CVE-2022-39357","score":0.01366,"percentile":0.7183,"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).
