CVE-2026-49203
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 · uneditedCrucial management API endpoints for cellular eSIM allocation do not validate caller authorization, allowing remote profiles to be rewritten or deleted.
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 · moderate confidenceThe vulnerability exists in cellular eSIM management API endpoints that handle profile allocation. These critical endpoints lack proper caller authorization validation, enabling remote unauthenticated actors to rewrite or delete eSIM profiles. This represents a broken access control vulnerability in the eSIM provisioning infrastructure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device model and firmware versionAccess the device administration interface or check the device label for the model (Acer Connect M6e 5g) and navigate to firmware/version settings to determine the installed firmware versionAffected if Firmware version is m6e_ai_1.00.000019 or earlier (the <= range indicates earlier versions are also affected)
-
Locate eSIM management API endpoint availabilityReview device documentation or perform network reconnaissance to identify if eSIM management API endpoints (typically paths like /api/esim, /esim/profiles, or similar cellular provisioning URLs) are exposed on the deviceAffected if eSIM management API endpoints are accessible on the device (even behind authentication)
-
Verify API authorization controls existExamine API responses or configuration files for presence of authorization validation logic - check whether API calls include role-based access control (RBAC) checks, profile ownership validation, or permission checks before allowing profile modification or deletion operationsAffected if API accepts and processes profile write/delete requests without verifying caller has permission to modify that specific profile (authentication present but authorization missing)
-
Test API behavior with unauthorized requestsIf accessible, attempt to send a profile modification or deletion request to the eSIM API from an account without administrative privileges or from a context without proper profile access rights, and observe if the operation is accepted or rejectedAffected if The API allows profile manipulation without proper authorization validation (operation succeeds when it should fail)
A user is affected if they have an Acer Connect M6e 5g device running firmware m6e_ai_1.00.000019 or earlier with exposed eSIM management API endpoints that accept profile modifications without verifying caller authorization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement robust authentication and authorization checks on all eSIM management API endpoints, including role-based access control (RBAC) to ensure only authorized systems or personnel can modify cellular profiles.
