## What is CVE-2026-102608?

CVE-2026-102608 is a critical command injection vulnerability in zoneminder, published on 16 Oct 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

ZoneMinder is a free, open source closed-circuit television software application. Prior to 1.38.3, downloadEvents() manually wraps a monitor Name value in single quotes instead of using escapeshellarg() before placing it in shell commands when a user with monitor-create or monitor-edit permission stores a monitor Name containing shell metacharacters and a user with Events View permission exports that monitor's events. In this attack mechanism, the stored monitor Name reaches both the ffmpeg concatenation command and the tar or zip archive command and breaks out of manual quoting. Arbitrary commands execute as the web server user. This issue is fixed in version 1.38.3.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

What it is: CVE-2026-102608 is a critical command injection vulnerability in zoneminder, published on 16 Oct 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-102608 in the wild and no public exploit code.

Affected product: zoneminder. 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.
