Local information disclosure requiring user interaction
Published Oct 13, 2026 · Updated Oct 13, 2026
Out-of-bounds read in Microsoft Office Excel allows attackers to disclose information locally via unspecified vectors. The public record does not identify the affected function, triggering input, or how the out-of-bounds data becomes visible. Exploitation requires user interaction but no attacker privileges; the documented consequence is information disclosure, not data modification or service interruption.
