{"cve":"CVE-2026-55886","nvd":{"published":"2026-07-01T21:17:04.220","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. 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.","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-vpmm-x3fm-qr5c","https://github.com/xdan/jodit/security/advisories/GHSA-vpmm-x3fm-qr5c"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-55886","score":0.00534,"percentile":0.44774,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-vpmm-x3fm-qr5c","url":"https://osv.dev/vulnerability/GHSA-vpmm-x3fm-qr5c","summary":"jodit: Prototype pollution in Jodit via Jodit.modules.Helpers.set()","modified":"2026-07-31T14:45:18.913847711Z","packages":[{"ecosystem":"npm","name":"jodit","purl":"pkg:npm/jodit","ranges":["<4.12.26"],"fixed":["4.12.26"]}]}],"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).
