CVE-2026-63409
Last modified
CVE-2026-63409 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. Deskflow is a keyboard and mouse sharing app. From 1.17.0 until continuous build 1.26.0.296, a malicious Deskflow server can send an odd-length DSOP vector to ServerProxy::setOptions() in src/lib/client/ServerProxy.cpp, causing the missing value after the final option key to be read beyond the vector during the PacketStreamFilter::filterEvent to ServerProxy::handleData() to ServerProxy::parseHandshakeMessage() call chain and crash the connected client. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
