CVE-2026-20993

Analysis

Samsung Assistant prior to version 9.3.10.7 improperly exports certain Android application components. This security flaw arises from misconfigured component access controls, allowing other local applications or processes to invoke or interact with these components without proper authorization [1].

To exploit this vulnerability, an attacker must have already installed a malicious application on the device or have local access. No special privileges beyond local app execution are required, as the improper export makes the components accessible to any app running on the same device. The attack surface is thus limited to local exploitation, but it does not require additional authentication or network access [1].

The primary impact is information disclosure: a local attacker can leverage the improperly exported components to read saved information stored by Samsung Assistant. This could include sensitive data such as user preferences, cached content, or other personal information managed by the assistant feature, potentially leading to privacy breaches or further targeted attacks [1].

Samsung has addressed this issue by releasing version 9.3.10.7 of Samsung Assistant, which corrects the component export configuration. Users are advised to update their devices through the official Samsung update channel to mitigate the risk. No workarounds were published for earlier versions [1].
