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.","state":0,"publishedAt":"2026-07-01T20:29:17.924+00:00","modifiedAt":"2026-07-02T14:41:32.037+00:00","affected":[{"ecosystem":"Vendor product","name":"jodit","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"xdan\",\n                    \"product\": \"jodit\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.12.18\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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,"severity":"MEDIUM"}],"references":["https://github.com/xdan/jodit/security/advisories/GHSA-5957-5c94-3v7w"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54756","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54756","identifiers":["CVE-2026-54756"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
