CVE-2023-22499

24
FAUCET Score

CVE-2023-22499 is a high-severity vulnerability affecting Deno, a JavaScript/TypeScript runtime. It allows multi-threaded programs to spoof interactive permission prompts, tricking users into granting unintended permissions by clearing the screen and displaying a misleading message. The CVSS score of 7.5 reflects a high impact on confidentiality, integrity, and availability, with a network attack vector and high attack complexity requiring user interaction. While there is no evidence of active exploitation, public exploit code, or significant community discussion, Deno users are strongly advised to upgrade to v1.29.3 or use the --no-prompt flag as a mitigation.
