CVE-2026-118780
Forge: verifyCertificateChain() removes trusted CA certificates with the same subject from the CA store
Impact
Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, the affected implementation used pki.verifyCertificateChain(), pki.createCaStore(), duplicate subject names to process the relevant input or security decision. node-forge modified the CA store while trying certificates that shared a subject name during pki.verifyCertificateChain(). A failed chain verification could permanently remove trusted CA certificates from the store, causing later valid chains to fail and creating a persistent availability impact for applications that reused the store. This issue is fixed in version 1.4.1.
