Arbitrary code execution via unchecked playlist data
Published Aug 21, 2025 · Updated May 15, 2026
Stack-based buffer overflow in Encorex Xenorate 2.50 and earlier allows attackers to execute arbitrary code via a crafted .xpl playlist. The .xpl parser accepts more than 88 attacker-controlled bytes without a bounds check, overwriting the SEH record used to redirect execution. Exploitation requires a user to open the file, and the resulting code runs with that user's application privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
