Descripción técnica

Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, node-forge parsed deprecated extension OIDs 2.5.29.10 and 2.5.29.13 as basicConstraints, and pki.verifyCertificateChain() used the first extension with that name. Exploitation requires a CA trusted by the application to issue a certificate carrying an attacker-supplied deprecated-OID extension, commonly because the CA copies extensions from a certificate signing request. By placing a permissive deprecated extension before the genuine 2.5.29.19 basicConstraints extension, the certificate holder could have the certificate accepted as a CA and issue certificates for arbitrary names, enabling server or client impersonation. If the issuing CA adds a keyUsage extension without keyCertSign, node-forge rejects the chain. This issue is fixed in version 1.4.1.

———Under certain conditions, privilege manager agent allows a remote unauthenticated attacker to execute arbitrary code as LocalSystem.11h CVE-2026-1192006.5 MED

———Nuxt is an open-source web development framework for Vue.js. From 4.6.0 until 4.6.3, Nuxt resolves literal or percent-encoded dot segments before rendering a page while Nitro routing, server/middleware checks, and server route rules evaluate the unresolved path. A request such as /%2e/admin can therefore render app/pages/admin.vue and its server-rendered data while checks keyed to /admin, redirects, or per-route security headers do not apply. API handlers, appMiddleware, Nuxt 3, and Nuxt 4.0.0 through 4.5.x are not affected, and exploitation requires a client that sends dot segments without browser normalization. This issue is fixed in version 4.6.3.13h CVE-2026-1191895.9 MED

———Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, node-forge enforced an X.509 CA certificate's basicConstraints.pathLenConstraint only when that certificate also carried a keyUsage extension. Exploitation requires a path-length-constrained CA without keyUsage that chains to a root trusted by the application, and an attacker who holds that CA's private key or obtains a subordinate CA certificate from it. The attacker could then construct a chain exceeding the declared path length that still passed pki.verifyCertificateChain(). Public web PKI CA certificates normally include keyUsage; private PKIs with CA certificates created without it are more likely to be affected. This issue is fixed in version 1.4.1.14h CVE-2026-1187803.7 BAJ

———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 1.4.1.15h CVE-2026-1191186.5 MED

———Crawl4AI before 0.9.5 contains an improper certificate validation vulnerability that allows network attackers to intercept crawls because Chromium always launches with --ignore-certificate-errors. Man-in-the-middle or DNS-controlling attackers can serve forged content to the crawler and read cookies and headers sent, while hard-coded --no-sandbox also overrides CRAWL4AI_CHROMIUM_SANDBOX.13h CVE-2026-106036—

———Szafir accepts any client or server certificate without performing certificate and hostname validation, allowing HTTPS connections without authenticating the remote server. An attacker can provide an arbitrary SSL/TLS certificate and cause the application to download an update file from their server. This issue was fixed in version 2.0 build 708.17h
