{"cve":"CVE-2026-54756","nvd":{"published":"2026-07-01T21:17:03.553","modified":"2026-10-25T16:10:00.147","status":"Deferred","description":"Jodit Editor is a WYSIWYG editor with written in pure TypeScript file and image editing capabilities. In versions prior to 4.12.18, Jodit.configure(options) — and the internal ConfigMerge / ConfigProto helpers — merged user-supplied options into the editor configuration without filtering prototype-mutating keys, potentially causing a Prototype Pollution vulnerability. A payload nested under an existing plain-object option such as controls could reach and mutate Object.prototype. Applications that pass user-controlled or partially user-controlled configuration into Jodit.configure() may be vulnerable. This issue was fixed in version 4.12.18.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":null,"cwes":["CWE-1321"],"references":["https://github.com/xdan/jodit/security/advisories/GHSA-5957-5c94-3v7w","https://github.com/xdan/jodit/security/advisories/GHSA-5957-5c94-3v7w"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-54756","score":0.00462,"percentile":0.39798,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5957-5c94-3v7w","url":"https://osv.dev/vulnerability/GHSA-5957-5c94-3v7w","summary":"Jodit has prototype pollution via Jodit.configure() / ConfigMerge","modified":"2026-07-31T19:15:24.222131123Z","packages":[{"ecosystem":"npm","name":"jodit","purl":"pkg:npm/jodit","ranges":["<4.12.18"],"fixed":["4.12.18"]}]}],"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).
