Use of a Broken or Risky Cryptographic Algorithm

CVE-2025-27508

High
7.5/10

Summary

Emissary is a P2P-based data-driven workflow engine. The "ChecksumCalculator" class allows for hashing and checksum generation, but it includes or defaults to algorithms that are no longer recommended for secure cryptographic use cases (e.g., SHA-1, CRC32, and SSDEEP). While possibly valid for certain non-security-critical tasks, these algorithms can expose users to security risks if used in scenarios where strong cryptographic guarantees are required. This issue affects Emissary versions prior to 8.24.0.
