Emissary is a P2P based data-driven workflow engine. The ChecksumCalculator class within allows for hashing and checksum generation, but it includes or defaults to algorithms that are no longer recommended for secure cryptographic use cases, such as SHA-1, CRC32, and SSDEEP. These algorithms can expose users to security risks if used in scenarios where strong cryptographic guarantees are required.

A Denial of Service (DoS) condition was identified in Next.js, which can trigger a crash and affect the availability of the server upon exploitation. This issue can affect all Next.js deployments on the affected versions.
