{"id":"CVE-2026-125332","published":"2026-11-10T19:21:10.783","lastModified":"2026-11-10T21:46:38.000","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 accepts a ServerHello compression_method that it did not offer. When the client later handles ServerHelloDone, tls.createConnectionState() rejects the unsupported compression algorithm by throwing an Error that propagates from connection.process(). A malicious server or an on-path attacker can alter the unauthenticated ServerHello compression byte before the server Finished message and terminate a Node.js process when the application does not catch the exception. The affected client paths include direct forge.tls use, forge.tls.wrapSocket, and forge.http; forge.tls servers are not affected, and the issue has 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-20","CWE-248"],"vendors":[],"products":[],"references":[{"url":"https://github.com/digitalbazaar/forge/commit/1d9816d333c23c523ef2bd8b24282c87db2654ef","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-w4xr-hqv8-ch44","tags":[]}],"exploitRefs":[{"url":"https://github.com/digitalbazaar/forge/commit/1d9816d333c23c523ef2bd8b24282c87db2654ef","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-w4xr-hqv8-ch44","tags":[]}],"hasPoc":true,"ai":null}
