Strapi users-permissions plugin fails to restrict JWT algorithms when plugin::users-permissions.jwt.algorithm is not explicitly configured, allowing acceptance of HS384 and HS512 tokens alongside HS256. Attackers possessing the jwtSecret can mint tokens with non-standard HMAC variants to bypass algorithm restrictions and weaken authentication controls.

——17Bleichenbacher's attack on PKCS #1 v1.5 padding for RSA in STM32 cryptographic firmware library software expansion for STM32Cube (UM1924). The vulnerability can allow one to use Bleichenbacher's oracle attack to decrypt an encrypted ciphertext by making successive queries to the server using the vulnerable library, resulting in remote information disclosure.9dCVE-2020-254937.5 HIG55.2%
——17Oclean Mobile Application 2.1.2 communicates with an external website using HTTP so it is possible to eavesdrop the network traffic. The content of HTTP payload is encrypted using XOR with a hardcoded key, which allows for the possibility to decode the traffic.9dCVE-2020-209505.9 MED54.4%
