CVE-2024-20829
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMissing proper interaction for opening deeplink in Samsung Internet prior to version v24.0.0.0 allows remote attackers to open an application without proper interaction.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSamsung Internet browser versions prior to v24.0.0.0 contain a vulnerability where deeplinks can be opened without proper user interaction. This missing validation allows remote attackers hosting malicious webpages to automatically launch arbitrary applications on the user's device without confirmation, potentially leading to unintended app execution or phishing scenarios.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Find installed Samsung Internet versionOpen Android Settings > Apps > Samsung Internet, or open Play Store and search for Samsung Internet to view the installed versionAffected if The displayed version is below 24.0.0.0 (for example 23.x, 22.x, etc.)
-
Verify deeplink behavior (if version is below 24.0.0.0)Host a webpage with a malicious deeplink (e.g., tel://, geo://, or other custom scheme) and access it via Samsung Internet - the browser may automatically launch the target app without user confirmationAffected if The target application launches automatically without any user prompt or confirmation dialog appearing
-
Confirm browser is default handlerCheck if Samsung Internet is set as the default browser for handling deeplinks in Android Settings > Apps > Default apps > Browser appAffected if Samsung Internet is the default browser and the vulnerability is present in the installed version
A user is affected if Samsung Internet browser version is below 24.0.0.0 and deeplinks from malicious webpages can open apps automatically without user interaction.
