## What is CVE-2026-26334?

CVE-2026-26334 is a high-severity vulnerability in Calero VeraSMART, published on 13 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Calero VeraSMART versions prior to 2026 R1 contain hardcoded static AES encryption keys within Veramark.Framework.dll (Veramark.Core.Config class). These keys are used to encrypt the password of the service account stored in C:\\VeraSMART Data\\app.settings. An attacker with local access to the system can extract the hardcoded keys from the Veramark.Framework.dll module and decrypt the stored credentials. The recovered credentials can then be used to authenticate to the Windows host, potentially resulting in local privilege escalation depending on the privileges of the configured service account.

Weakness: CWE-798 (Use of Hard-coded Credentials)

Check this codebase for CVE-2026-26334 and fix it if it is affected.

What it is: CVE-2026-26334 is a high-severity vulnerability in Calero VeraSMART, published on 13 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-26334 in the wild and no public exploit code.

Affected product: Calero VeraSMART. 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.
