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...

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...

PT-2026-85226

Name of the Vulnerable Software and Affected Versions node-forge versions prior to 1.4.1 Description An issue exists during RSA PKCS1 v1.5 signature verification where the software fails to validate the element count in nested DigestAlgorithm sequences. This allows attackers to embed garbage byte...

PT-2026-28557

Name of the Vulnerable Software and Affected Versions Forge versions prior to 1.4.0 Description Forge, a native implementation of Transport Layer Security in JavaScript, has a flaw in its RSASSA PKCS1 v1.5 signature verification process.

ENS DNSSEC Oracle Vulnerable to RSA Signature Forgery via Missing PKCS#1 v1.5 Padding Validation

Impact The RSASHA256Algorithm and RSASHA1Algorithm contracts fail to validate PKCS1 v1.5 padding structure when verifying RSA signatures. The contracts only check if the last 32 or 20 bytes of the decrypted signature match the expected hash. This enables Bleichenbacher's 2006 signature forgery...
