AndBible Arbitrary Code Execution via Crafted Module Upload

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-107057

AndBible is a mobile Android application. It is client-side software intended for personal use rather than an internet-facing service, API, or infrastructure component. The vulnerability requires user-initiated action to upload a crafted file into the local application environment, which is not a typical public-internet-facing attack surface.

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

External exposure likelihood

Horizon Alert

Summary of the vulnerability and why it matters

An identified critical vulnerability in the AndBible application could allow unauthorized code execution through the upload of a specially crafted file. While this vulnerability is present, its actual risk to our organization is considered very unlikely due to the nature of the application and the specific user actions required for exploitation. The primary concern at this time is to confirm if this application is in use within our environment.

  • Malicious code can be uploaded to the app.
  • Confirm if this personal app is used internally.
  • Focus on relevance, not immediate technical fixes.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by uploading a specially crafted zip file. This allows them to execute arbitrary code on the affected device, as the application does not sufficiently validate the contents of uploaded modules.

  • Unauthenticated network access required.
  • Uploading a crafted module zip.
  • Arbitrary code execution.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated attacker to execute arbitrary code on a user's device by uploading a specially crafted zip file, potentially leading to a compromise of the application and any data it accesses.

  • Application code and user-installed modules.
  • Uploading a malicious zip file.
  • Arbitrary code execution on the device.

Operational Fix

Recommended remediation, mitigation, and detection steps

For this CVE, the primary responsibility likely falls to the application owner or the team managing the AndBible deployment, supported by the security or platform team for risk assessment and remediation planning. The first practical step is to identify all instances of AndBible, determine their reachability and criticality, confirm the accountable owner for each instance, and then develop a remediation plan based on the identified risks and operational constraints.

  • Application owners should coordinate remediation.
  • Verify AndBible instances and their reachability.
  • Plan remediation based on risk and impact.

Frequently asked questions

What is AndBible?

AndBible is an open-source, mobile Android application designed for personal Bible study. It allows users to read scripture, use reference tools, and extend its functionality by importing customized module files, which typically contain supplemental text or study materials.

What does CWE-926 mean for CVE-2026-107057?

This CVE involves CWE-926, which refers to improper validation of files or permissions. In this case, the application fails to properly check the contents of a module zip file before processing it, which could allow a malicious file to run unauthorized commands on the device.

How does an attacker trigger this vulnerability?

An attacker would need to trick a user into uploading a specially crafted zip file into the application as a module. Simply having the app installed or connected to the internet does not trigger the bug; the vulnerability requires an explicit user action to import the malicious file.

Is my device at risk based on Halo Surface Signal?

Halo Surface Signal indicates that this risk is very unlikely because AndBible is a client-side mobile app, not an internet-facing server. Since the app is intended for personal use and requires manual file interaction, it does not present a standard remote network attack surface.

What should I do if AndBible is installed?

The first step is to confirm if the application is in use within your environment. If identified, evaluate its purpose and reachability. Coordinate with the application owner or your security team to track the situation and plan for updates or removal according to your internal policies.
