CVE-2026-17902Network attack vector

Clipboard image disclosure via cross-buffer paste

Published Jul 30, 2026 · Updated Jul 30, 2026

Information disclosure in Google Chrome's Editing component before 151.0.7922.72 on Linux allows remote attackers to read clipboard images. ClipboardCommands::GetFragmentFromClipboard hardcodes the standard clipboard for its image fallback instead of honoring the active PRIMARY selection, inserting the wrong buffer's image as a data URL into editable content. Exploitation requires a user to middle-click paste in attacker-controlled editable content, where page listeners can capture the inserted image.
