Security readout for executives and security teams
Plain-English summary
A malicious webpage may cause Microsoft Edge to fill stored contact information after two consecutive taps without clear user intent. The likely impact is limited privacy exposure, such as an address, email, or phone number. It does not affect data integrity or availability according to the supplied CVSS assessment.
Executive priority
Handle through the normal browser patch cycle rather than emergency response, unless sensitive environments have extensive autofill use or delayed Edge updates. Prioritize confirming deployed versions because the supplied affected-version information is incomplete.
Technical view
CVE-2026-0102 is a CWE-359 privacy weakness in Chromium-based Microsoft Edge. Exploitation requires network access, high complexity, and user interaction. Successful triggering may disclose limited autofill metadata. The supplied CVSS v3.1 score is 3.1, with low confidentiality impact and no integrity or availability impact.
Likely exposure
Exposure is limited to users of affected Chromium-based Edge builds who have relevant autofill data stored and interact with a malicious webpage. The bundle lists version 1.0.0.0 but provides no reliable affected-build range or fixed-build number, so organizations should confirm applicability through Microsoft’s advisory and endpoint inventory.
Exploitation context
The supplied bundle does not provide evidence of active exploitation, and the CVE is not identified as KEV. Abuse requires a victim to visit a malicious webpage and perform two consecutive taps under specific conditions. High attack complexity and required user interaction reduce likelihood, but stored personal information may still be exposed.
Researcher notes
The provided vector is AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N with E:U, RL:O, and RC:C. The bundle does not describe the underlying browser mechanism, affected build range, fixed build, proof of concept, or observed attacks. Testing should remain defensive and avoid exposing real stored personal data.
Mitigation direction
- Review Microsoft’s advisory for affected and fixed Edge build information.
- Update Microsoft Edge through the organization’s approved maintenance process.
- Consider limiting stored autofill data on higher-risk or shared endpoints.
- Recheck Microsoft guidance if an applicable fixed build cannot be confirmed.
Validation and detection
- Inventory deployed Microsoft Edge versions across managed endpoints.
- Compare installed builds with Microsoft’s current affected and fixed version guidance.
- Confirm browser update policies are enabled and successfully applying updates.
- Verify sensitive or shared endpoints do not retain unnecessary autofill information.

Exposure of Private Personal Information to an Unauthorized Actor
Exposure of Private Personal Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
