## What is CVE-2026-40623?

CVE-2026-40623 is a high-severity missing authorization vulnerability in SenseLive X3050, published on 23 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A vulnerability in SenseLive X3050's web management interface allows critical system and network configuration parameters to be modified without sufficient validation and safety controls. Due to inadequate enforcement of constraints on sensitive functions, parameters such as IP addressing, watchdog timers, reconnect intervals, and service ports can be set to unsupported or unsafe values. These configuration changes directly affect core device behaviour and recovery mechanisms. The lack of proper validation and safeguards allows critical system functions to be altered in a manner that can destabilize device operation or render the device persistently unavailable.

Weakness: CWE-862 (Missing Authorization)

Check this codebase for CVE-2026-40623 and fix it if it is affected.

What it is: CVE-2026-40623 is a high-severity missing authorization vulnerability in SenseLive X3050, published on 23 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-40623 in the wild and no public exploit code.

Affected product: SenseLive X3050. 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.
