Deno versions prior to 2.6.0
Description
Deno is a JavaScript, TypeScript, and WebAssembly runtime. A flaw in the
node:crypto polyfill allows cryptographic handles to persist beyond their intended lifespan. This results in the possibility of infinite encryption rounds, potentially enabling attackers to attempt brute-force attacks or learn server secrets. The issue stems from the node:crypto module not finalizing ciphers correctly.Recommendations
Upgrade to Deno version 2.6.0 or newer.
