{"id":"CVE-2026-125334","published":"2026-11-10T19:21:11.090","lastModified":"2026-11-10T21:46:34.010","description":"Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.3, a forge.tls client can pass a handshake record to tls.handleHandshake() while the connection has no session, including after a close_notify alert, after the application calls close(), or before handshake() is called. The handler dereferences c.session.md5 before dispatching the message, causing a TypeError to propagate from connection.process(). A malicious server or on-path attacker can deliver the record, including after a reset when the connection uses no encryption, and terminate a Node.js process if the application does not catch the exception. forge.tls servers are not affected, and there is no confidentiality or integrity impact. This issue is fixed in version 1.4.3.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-476"],"vendors":[],"products":[],"references":[{"url":"https://github.com/digitalbazaar/forge/commit/2cfaeb516cb3d4aff1c0569d39394df41c5cb17c","tags":[]},{"url":"https://github.com/digitalbazaar/forge/pull/1169","tags":[]},{"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.3","tags":[]},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-j8rw-jp99-435v","tags":[]}],"exploitRefs":[{"url":"https://github.com/digitalbazaar/forge/commit/2cfaeb516cb3d4aff1c0569d39394df41c5cb17c","tags":[]},{"url":"https://github.com/digitalbazaar/forge/pull/1169","tags":[]},{"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.3","tags":[]},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-j8rw-jp99-435v","tags":[]}],"hasPoc":true,"ai":null}
