## What is CVE-2026-4606?

CVE-2026-4606 is a critical vulnerability in GeoVision GV-Edge Recording Manager, published on 23 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

GV Edge Recording Manager (ERM) v2.3.1 improperly runs application components with SYSTEM-level privileges, allowing any local user to gain full control of the operating system. 

During installation, ERM creates a Windows service that runs under the LocalSystem account. 

When the ERM application is launched, related processes are spawned under SYSTEM privileges rather than the security context of the logged-in user. 

Functions such as 'Import Data' open a Windows file dialog operating with SYSTEM permissions, enabling modification or deletion of protected system files and directories. 

Any ERM function invoking Windows file open/save dialogs exposes the same risk. 

This vulnerability allows local privilege escalation and may result in full system compromise.

Weakness: CWE-250 (Execution with Unnecessary Privileges)

What it is: CVE-2026-4606 is a critical vulnerability in GeoVision GV-Edge Recording Manager, published on 23 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-4606 in the wild and no public exploit code.

Affected product: GeoVision GV-Edge Recording Manager. 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.
