CVE-2021-26603 is a high-severity heap overflow vulnerability (CVSS 7.8) affecting the ARK library by Bandisoft, which is also used in some Microsoft Windows environments. The flaw stems from a lack of string length checks when the Ark_DigPathA function parses file paths, potentially leading to arbitrary code execution. Exploitation requires user interaction (e.g., opening a malicious file) and could result in complete compromise of confidentiality, integrity, and availability. There is currently no public exploit code available, nor is there evidence of active exploitation or significant community discussion surrounding this vulnerability.
