{"id":"UBUNTU-CVE-2026-125332","details":"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.","modified":"2026-11-12T23:46:37.023681215Z","published":"2026-11-12T00:00:00Z","upstream":["CVE-2026-125332"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-125332"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-125332"},{"type":"REPORT","url":"https://github.com/digitalbazaar/forge/commit/1d9816d333c23c523ef2bd8b24282c87db2654ef"},{"type":"REPORT","url":"https://github.com/digitalbazaar/forge/pull/1169"},{"type":"REPORT","url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.3"},{"type":"REPORT","url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-w4xr-hqv8-ch44"}],"affected":[{"package":{"name":"node-node-forge","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-node-forge?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.8.5~dfsg-2","0.9.1~dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-node-forge","binary_version":"0.9.1~dfsg-1"},{"binary_name":"node-node-forge","binary_version":"0.9.1~dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-125332.json"}},{"package":{"name":"node-node-forge","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-node-forge?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.0~dfsg-3","1.2.1~dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.1~dfsg-2","binary_name":"libjs-node-forge"},{"binary_version":"1.2.1~dfsg-2","binary_name":"node-node-forge"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-125332.json"}}],"schema_version":"1.9.2","severity":[{"type":"Ubuntu","score":"medium"}]}
