## What is CVE-2026-27615?

CVE-2026-27615 is a high-severity code injection vulnerability in Alex4SSB ADB-Explorer, published on 25 Feb 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

ADB Explorer is a fluent UI for ADB on Windows. In versions prior to Beta 0.9.26022, ADB-Explorer allows the `ManualAdbPath` settings variable, which determines the path of the ADB binary to be executed, to be set to a Universal Naming Convention (UNC) path in the application's settings file. This allows an attacker to set the binary's path to point to a remote network resource, hosted on an attacker-controlled network share, thus granting the attacker full control over the binary being executed by the app. An attacker may leverage this vulnerability to execute code remotely on a victim's machine with the privileges of the user running the app. Exploitation is made possible by convincing a victim to run a shortcut of the app that points to a custom `App.txt` settings file, which sets `ManualAdbPath` (for example, when downloaded in an archive file). Version Beta 0.9.26022 fixes the issue.

Weakness: CWE-829 (Inclusion of Functionality from Untrusted Control Sphere), CWE-40 (Path Traversal: '\\UNC\share\name\' (Windows UNC Share))

What it is: CVE-2026-27615 is a high-severity code injection vulnerability in Alex4SSB ADB-Explorer, published on 25 Feb 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-27615 exists.

Affected product: Alex4SSB ADB-Explorer. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
