CVE-2026-41244
Mojic: Observable Timing Discrepancy in HMAC Verification
Description
Mojic is a CLI tool to transform readable C code into an unrecognizable chaotic stream of emojis. Prior to 2.1.4, the CipherEngine uses a standard equality operator (!==) to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy (CWE-208), allowing a potential attacker to bypass the file integrity check via a timing attack. This vulnerability is fixed in 2.1.4.

Action Type Old Value New Value Added Translation Title: mojic de notamitgamer, Description: Mojic es una herramienta CLI para transformar código C legible en un flujo caótico e irreconocible de emojis. Antes de la versión 2.1.4, el CipherEngine utiliza un operador de igualdad estándar (!==) para verificar el sello de integridad HMAC-SHA256 durante la fase de descifrado. Esto crea una Discrepancia de Tiempo Observable (CWE-208), permitiendo a un potencial atacante eludir la verificación de integridad del archivo mediante un ataque de temporización. Esta vulnerabilidad está corregida en la versión 2.1.4. -
