CVE-2026-33894

Forge (node-forge) prior to version 1.4.0 is vulnerable to RSASSA-PKCS1 v1.5 signature forgery for low exponent keys (e = 3). The issue arises from forging signatures by injecting extra bytes inside the ASN.1 structure and by not enforcing a minimum PKCS#1 v1.5 padding length of 8 bytes, enabling...

Name of the Vulnerable Software and Affected Versions Forge also called node-forge versions prior to 1.4.0 Description Forge, a native implementation of Transport Layer Security in JavaScript, contains an issue in Ed25519 signature verification. Specifically, the verification process does not...

Forge has signature forgery in Ed25519 due to missing S > L check

Summary Ed25519 signature verification accepts forged non-canonical signatures where the scalar S is not reduced modulo the group order S = L. A valid signature and its S + L variant both verify in forge, while Node.js crypto.verify OpenSSL-backed rejects the S + L variant, as defined by the...

Improper Verification of Cryptographic Signature

Overview org.webjars.npm:node-forge is a WebJar for node-forge. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in ASN.1 structures during RSA signature verification. An attacker can bypass signature verification and inject forged signatures by...

Forge has signature forgery in RSA-PKCS due to ASN.1 extra field

Summary RSASSA PKCS1 v1.5 signature verification accepts forged signatures for low public exponent keys e=3. Attackers can forge signatures by stuffing “garbage” bytes within the ASN structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This...

RUSTSEC-2026-0075 All-Zero Key Generation on Catastrophic RNG Failure

The libcrux-ed25519 key generation samples Ed25519 secret keys from a provided CSPRNG in a loop for up to 100 attempts until a non-zero key is found. If a non-zero key could not be sampled within 100 attempts the key generation function would silently continue with an all-zero buffer as the secre...
