## What is CVE-2025-59098?

CVE-2025-59098 is a high-severity vulnerability in dormakaba Access Manager 92xx-k5, published on 26 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The Access Manager is offering a trace functionality to debug errors and issues with the device. The trace functionality is implemented as a simple TCP socket. A tool called TraceClient.exe, provided by dormakaba via the Access Manager web interface, is used to connect to the socket and receive debug information. The data is permanently broadcasted on the TCP socket. The socket can be accessed without any authentication or encryption. 

The transmitted data is based on the set verbosity level. The verbosity level can be set using the http(s) endpoint with the service interface password or with the guessable identifier of the device via the SOAP interface.

The transmitted data contains sensitive data like the Card ID as well as all button presses on Registration units. This allows an attacker with network level access to retrieve all entered PINs on a registration unit.

Weakness: CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere)

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.
