CVE-2026-33895
Description
A flaw was found in Forge (also called node-forge), a JavaScript library used for Transport Layer Security (TLS). The library's Ed25519 signature verification process does not correctly validate cryptographic signatures, allowing forged non-canonical signatures to be accepted. A remote attacker could exploit this signature malleability to bypass authentication and authorization logic. This vulnerability can also circumvent security checks in applications that rely on the uniqueness of cryptographic signatures for functions such as deduplication or preventing replay attacks.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
