CVE-2026-41244: CWE-208: Observable Timing Discrepancy in notamitgamer mojic
Mojic versions prior to 2. 1. 4 contain a timing side-channel vulnerability in the CipherEngine's HMAC-SHA256 integrity verification. The use of a standard equality operator (! ==) during decryption causes an observable timing discrepancy (CWE-208), which could allow an attacker to bypass the file integrity check via timing analysis. This vulnerability has a medium severity rating and a CVSS score of 4. 7. The issue is fixed in version 2. 1. 4.
AI Analysis
Technical Summary
Mojic is a CLI tool that transforms C code into emoji streams. Versions before 2.1.4 use a non-constant-time comparison (!==) to verify the HMAC-SHA256 integrity seal during decryption. This introduces an observable timing discrepancy (CWE-208), enabling potential timing attacks to bypass integrity checks. The vulnerability is addressed in version 2.1.4 by presumably implementing a constant-time comparison.
Potential Impact
An attacker with local access could exploit the timing discrepancy to bypass the file integrity check, potentially leading to unauthorized acceptance of tampered or corrupted files. The vulnerability does not affect confidentiality or availability but impacts integrity. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade Mojic to version 2.1.4 or later, where the timing discrepancy vulnerability is fixed. No other mitigation steps are indicated or required.
