CVE-2026-18907Network attack vector

Arbitrary file write via path traversal filename

Published Aug 5, 2026 · Updated Aug 5, 2026

Relative path traversal in Hola Browser 2.23.1.1 for Android allows remote attackers to write arbitrary files through downloads. The download feature accepts traversal sequences in a filename and uses the resulting path for the file write without neutralizing those sequences. Exploitation requires control of the download filename, and writes remain limited to locations allowed by the Android application sandbox.
