CVE-2021-20745 is a critical vulnerability affecting Inkdrop versions prior to v5.3.1, enabling arbitrary OS command execution. An attacker can exploit this by crafting a malicious file or code snippet with an invalid iframe, which, when loaded into Inkdrop, executes commands on the user's system. With a CVSS score of 7.8 (High), this vulnerability requires user interaction (UI:R) but has low attack complexity (AC:L) and can lead to high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB: None), it is not listed on the KEV catalog, and there is no significant community discussion or media coverage, suggesting it is not actively exploited in the wild.
