CVE-2021-21797 is a high-severity double-free vulnerability in the JavaScript implementation of Nitro Pro PDF, affecting gonitro nitro_pro. An attacker can exploit this by crafting a malicious document that, when opened, causes a reference to be released twice, potentially leading to arbitrary code execution within the application's context. The CVSS score of 7.8 indicates a high impact with high confidentiality, integrity, and availability concerns, requiring user interaction but with low attack complexity. Despite its high EPSS and FAUCET Risk Score, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
