{"id":"CVE-2026-54756","aliases":["GHSA-5957-5c94-3v7w"],"url":"https://o3.security/vulnerability/CVE-2026-54756","summary":"Jodit Editor: Prototype pollution via Jodit.configure() / ConfigMerge","details":"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.","published":"2026-07-01T20:29:17.924Z","modified":"2026-08-12T03:51:34.934729693Z","cvss":null,"epss":{"score":0.00462,"percentile":0.39067,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"jodit","fixedVersion":"4.12.18"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54756.json"},{"type":"ADVISORY","url":"https://github.com/xdan/jodit/security/advisories/GHSA-5957-5c94-3v7w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54756"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:34.934729693Z"}}
