CVE-2026-6291

CVE-2026-6291 affects wolfSSL (v4.0) and describes a Bleichenbacher padding oracle in PKCS#7 KTRI RSA PKCS#1 v1.5 decryption used for EnvelopedData. The vulnerability arises because error codes differed between RSA padding validation failure and malformed decrypted content, enabling an attacker t...

PHP JWT Library: RSA1_5 (RSAES-PKCS1-v1_5) decryption lacks implicit rejection, exposing a Bleichenbacher/Marvin padding oracle

Impact RSACrypt::decryptWithRSA15 used by the RSA15 key-encryption algorithm implements RSAES-PKCS1-v15 decryption by inspecting the padding after RSADP and throwing InvalidArgumentException as soon as the padding is malformed. It does not implement the implicit-rejection countermeasure required ...
