CVE-2026-85085Network attack vector

Session-backed application access via unverified WebView origin

Published Sep 4, 2026 · Updated Sep 4, 2026

Origin-verification failure in Canva for Android before 2.376.0 allows remote attackers to access Canva through a user's session. The privileged WebView accepts an external origin without verifying that the loaded page is an expected source before exposing session-backed communication. Exploitation requires a user to load an attacker-controlled page; the published record does not identify the exposed session operations or a narrower code locus.
