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."}],"source":{"advisory":"GHSA-vpmm-x3fm-qr5c","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/xdan/jodit/security/advisories/GHSA-vpmm-x3fm-qr5c","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-02T12:22:09.347068Z","id":"CVE-2026-55886","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-02T12:22:32.358Z"}}]}}
