Broadcast Receiver Privilege Escalation

Published Jun 4, 2026 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed
Description
Unchecked public access permissions on a core Broadcast Receiver allow unauthorized local software components to invoke administrative operations.

Analysis

AI-generated

Technical impact

Unchecked public access permissions on a core Broadcast Receiver allow local software components to trigger administrative operations without proper authorization. This flaw can be leveraged to gain elevated privileges on the device, enabling an attacker to perform functions normally available only to the device’s administrative tenant. The primary consequence is local privilege escalation, potentially leading to total device compromise.

Affected Systems

Acer Connect M6E 5G Portable WiFi Router is the affected product. No specific firmware versions are listed in the advisory, so all current releases should be considered susceptible until a patch is released.

Risk and Exploitability

The CVSS score of 8.5 indicates a high severity for local privilege escalation. EPSS data is unavailable, and the vulnerability is not listed in the CISA KEV catalog, suggesting no known widespread exploitation at this time. The attack vector is inferred to be local; an attacker must execute code or otherwise invoke the broadcast on the target device. Once triggered, the malicious component can perform privileged administrative actions, potentially disabling the router, reconfiguring it, or accessing sensitive network traffic.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the router firmware to the latest version that includes a fix for the broadcast receiver permission issue.
  • If an update is not immediately available, restrict or disable the broadcast receiver functionality through the device’s configuration interface to prevent unauthorized invocations.
  • Ensure that only authenticated and authorized applications can access system broadcast mechanisms by reviewing and tightening local security settings and logs.
