CVE-2026-33996

LibJWT is a C JSON Web Token Library. Starting in version 3.0.0 and prior to version 3.3.0, the JWK parsing for RSA-PSS did not protect against a NULL value when expecting to parse JSON string values. A specially crafted JWK file could exploit this behavior by using integers in places where the...

CVE-2026-33996 LibJWT has NULL/bounds validation in JWK octet and RSA PSS parsing

LibJWT is a C JSON Web Token Library. Starting in version 3.0.0 and prior to version 3.3.0, the JWK parsing for RSA-PSS did not protect against a NULL value when expecting to parse JSON string values. A specially crafted JWK file could exploit this behavior by using integers in places where the...

CVE-2026-33894

A flaw was found in Forge also called node-forge, a JavaScript implementation of Transport Layer Security. A remote attacker could exploit weaknesses in the RSASSA PKCS1 v1.5 signature verification process. By crafting malicious signatures that include extra data within the ASN structure and do n...

CVE-2026-33894 Forge has signature forgery in RSA-PKCS due to ASN.1 extra field

Forge also called node-forge is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, 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...

libjwt 代码问题漏洞

LibJWT is a C-language library developed by Ben Collins, designed for generating and verifying JSON Web Tokens. Versions of LibJWT from 3.0.0 to 3.3.0 contained code vulnerabilities. These vulnerabilities stemmed from RSA-PSS’s JWK parsing mechanism, which did not properly handle empty values,...

PT-2026-28589

Name of the Vulnerable Software and Affected Versions LibJWT versions 3.0.0 through 3.2.9 Description LibJWT, a C JSON Web Token Library, has an issue in the RSA-PSS JWK parsing functionality. Versions prior to 3.3.0 do not adequately validate JSON string values, specifically failing to protect...

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...

Improper Verification of Cryptographic Signature

Overview node-forge is a JavaScript implementations of network transports, cryptography, ciphers, PKI, message digests, and various utilities. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in ASN.1 structures during RSA signature verification...

GHSA-PPP5-5V6C-4JWP 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...

SUSE-SU-2026:0975-1 Security update for python-Authlib

This update for python-Authlib fixes the following issues: - CVE-2026-27962: JWS deserializecompact allows for signature bypass by accepting user-controlled embedded JWK as verification key bsc1259738. - CVE-2026-28490: cryptographic padding oracle in JWE RSA15 key management algorithm bsc1259736...

CVE-2026-33488

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the createKeys function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the...

CVE-2026-33488 AVideo has a PGP 2FA Bypass via Cryptographically Broken 512-bit RSA Key Generation in LoginControl Plugin

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the createKeys function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the...

CVE-2026-4603

A flaw was found in jsrsasign. An attacker can exploit a division by zero vulnerability by supplying a specially crafted JSON Web Key JWK whose modulus decodes to zero. This vulnerability can force RSA public-key operations, such as verification and encryption, to produce deterministic zero...

jsrsasign: Division by Zero Allows Invalid JWK Modulus to Cause Deterministic Zero Output in RSA Operations

Versions of the package jsrsasign before 11.1.1 are vulnerable to Division by zero due to the RSASetPublic/KEYUTIL parsing path in ext/rsa.js and the BigInteger.modPowInt reduction logic in ext/jsbn.js. An attacker can force RSA public-key operations e.g., verify and encryption to collapse to...
