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":"2026-07-01T21:17:04.22+00:00","modifiedAt":"2026-07-02T15:12:53.577+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/xdan/jodit/security/advisories/GHSA-vpmm-x3fm-qr5c"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-55886","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-1321"],"productCriteria":[],"sourceDates":{"published":"2026-07-01T21:17:04.220","lastModified":"2026-07-02T15:12:53.577"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
