Versions prior to 4.12.26 are vulnerable to Prototype Pollution through Jodit.modules.Helpers.set(chain, value, obj), which walks the dot-separated chain, creating and following each path segment without filtering prototype-mutating keys. A chain that begins with (or contains) __proto__, constructor, or prototype lets the final assignment reach and mutate Object.prototype. Applications that pass a user-controlled or partially user-controlled key path into Jodit.modules.Helpers.set() could be vulnerable, causing unexpected property injection, logic bypass, denial of service, or secondary security issues. This issue has been fixed in version 4.12.26.","state":0,"publishedAt":"2026-07-01T20:25:43.632+00:00","modifiedAt":"2026-07-02T12:22:32.358+00:00","affected":[{"ecosystem":"Vendor product","name":"jodit","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"xdan\",\n                    \"product\": \"jodit\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.12.26\",\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-vpmm-x3fm-qr5c"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55886","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55886","identifiers":["CVE-2026-55886"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
