All the vulnerabilities related to the version 1.0.3 of the package
Prototype Pollution in node-forge debug API.
The forge.debug API had a potential prototype pollution issue if called with untrusted input. The API was only used for internal debug purposes in a safe way and never documented or advertised. It is suspected that uses of this API, if any exist, would likely not have used untrusted inputs in a vulnerable way.
The forge.debug API and related functions were removed in 1.0.0.
Don't use the forge.debug API directly or indirectly with untrusted input.
If you have any questions or comments about this advisory:
Open Redirect in node-forge
parseUrl functionality in node-forge mishandles certain uses of backslash such as https:/\/\/\ and interprets the URI as a relative path.
URL parsing in node-forge could lead to undesired behavior.
The regex used for the forge.util.parseUrl API would not properly parse certain inputs resulting in a parsed data structure that could lead to undesired behavior.
forge.util.parseUrl and other very old related URL APIs were removed in 1.0.0 in favor of letting applications use the more modern WHATWG URL Standard API.
Ensure code does not directly or indirectly call forge.util.parseUrl with untrusted input.

Improper Verification of Cryptographic Signature in node-forge
RSA PKCS#1 v1.5 signature verification code is not properly checking DigestInfo for a proper ASN.1 structure. This can lead to successful verification with signatures that contain invalid structures but a valid digest.
The issue has been addressed in node-forge 1.3.0.
If you have any questions or comments about this advisory:
Improper Verification of Cryptographic Signature in node-forge
RSA PKCS#1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used.
The issue has been addressed in node-forge 1.3.0.

Improper Verification of Cryptographic Signature in node-forge
RSA PKCS#1 v1.5 signature verification code does not check for tailing garbage bytes after decoding a DigestInfo ASN.1 structure. This can allow padding bytes to be removed and garbage data added to forge a signature when a low public exponent is being used.
The issue has been addressed in node-forge 1.3.0.
