## What is CVE-2025-59895?

CVE-2025-59895 is a high-severity denial of service vulnerability in Flexense Disk Pulse Enterprise, published on 28 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Sync Breeze Enterprise Server v10.4.18 and Disk Pulse Enterprise v10.4.18 contain a remote denial-of-service (DoS) vulnerability in the configuration restore functionality. The issue is due to insufficient validation of user-supplied data during this process. An attacker could send malicious requests to alter the configuration file, causing the application to become unresponsive. In a successful scenario, the service may not recover on its own and require a complete reinstallation, as the configuration becomes corrupted and prevents the service from restarting, even manually.

Weakness: CWE-20 (Improper Input Validation)

What it is: CVE-2025-59895 is a high-severity denial of service vulnerability in Flexense Disk Pulse Enterprise, published on 28 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-59895 in the wild and no public exploit code.

Affected product: Flexense Disk Pulse Enterprise. 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.
