## What is CVE-2026-23755?

CVE-2026-23755 is a high-severity vulnerability in D-Link D-View 8, published on 21 Jan 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

D-Link D-View 8 versions 2.0.1.107 and below contain an uncontrolled search path vulnerability in the installer. When executed with elevated privileges via UAC, the installer attempts to load version.dll from its execution directory, allowing DLL preloading. An attacker can supply a malicious version.dll alongside the legitimate installer so that, when a victim runs the installer and approves the UAC prompt, attacker-controlled code executes with administrator privileges. This can lead to full system compromise.

Weakness: CWE-427 (Uncontrolled Search Path Element)

What it is: CVE-2026-23755 is a high-severity vulnerability in D-Link D-View 8, published on 21 Jan 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: There is no known exploitation of CVE-2026-23755 in the wild and no public exploit code.

Affected product: D-Link D-View 8. 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.
