Hi, The following vulnerability was published for deskflow. CVE-2026-41476[0]: | Deskflow is a keyboard and mouse sharing app. Prior to 1.26.0.138, | a remote memory-safety vulnerability in Deskflow's clipboard | deserialization allows a connected peer to trigger an out-of-bounds | read by sending a malformed clipboard update. The issue is in the | implementation of src/lib/deskflow/IClipboard.cpp. This is reachable | because ClipboardChunk::assemble() in | src/lib/deskflow/ClipboardChunk.cpp validates only the outer | clipboard transfer size. It does not validate the internal structure | of the serialized clipboard blob, so malformed inner lengths reach | IClipboard::unmarshall() unchanged. This vulnerability is fixed in | 1.26.0.138. https://github.com/deskflow/deskflow/security/advisories/GHSA-3jp5-g964-cgmh If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
