Security readout for executives and security teams
Plain-English summary
Samsung Internet before version 14.0.1.62 had a component protection issue. In a specific condition, an untrusted application could make the browser execute an arbitrary activity. Business urgency depends on how many managed devices still run older Samsung Internet versions; the source bundle does not provide severity scoring or impact detail.
Executive priority
Treat this as a targeted mobile application update issue. Prioritize fleet inventory and upgrade compliance, but avoid emergency escalation unless internal exposure is high or new vendor evidence shows exploitation or higher impact.
Technical view
CVE-2021-25418 is mapped to CWE-269 and affects Samsung Internet before 14.0.1.62. The public description states improper component protection allowed untrusted applications to execute arbitrary activity under a specific condition. No CVSS vector, affected CPEs, or deeper technical prerequisites are provided in the bundle.
Likely exposure
Exposure is most likely on devices or fleets with Samsung Internet installed below 14.0.1.62. The source bundle lists Samsung Mobile Samsung Internet with unspecified affected versions, so exposure should be validated by installed application version rather than assumed broadly.
Exploitation context
The bundle does not report active exploitation, and KEV is false. The cited description does not provide exploit prerequisites, public proof-of-concept status, or evidence of attacks in the wild.
Researcher notes
Public evidence is sparse. The key known facts are affected product, fixed version boundary, CWE-269 classification, and the untrusted-application trigger. The phrase “specific condition” is not explained in the provided sources, limiting independent exposure modeling.
Mitigation direction
- Upgrade Samsung Internet to version 14.0.1.62 or later.
- Use Samsung’s June 2021 mobile security guidance for vendor-specific remediation details.
- Prioritize managed devices where Samsung Internet is present and outdated.
- Limit installation of untrusted applications through existing mobile device policy.
Validation and detection
- Inventory Samsung Internet versions across managed devices.
- Flag any installation below version 14.0.1.62.
- Confirm updated devices report Samsung Internet 14.0.1.62 or later.
- Track devices with missing application inventory as unresolved exposure.

Improper Privilege Management
Improper Privilege Management represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
