A peer exposes the gRPC API and HTTP API for consumption by other peers. These APIs allow peers to send requests that force the recipient peer to create files in arbitrary file system locations, and to read arbitrary files. This allows peers to steal other peers’ secret data and to gain remote code execution (RCE) capabilities on the peer’s machine.

file, err := os.OpenFile(t.DataFilePath, os.O_RDWR, defaultFileMode)
if err != nil {
       return 0, err
}
defer file.Close()
if _, err = file.Seek(req.Range.Start, io.SeekStart); err != nil {
       return 0, err
}
n, err := io.Copy(file, io.LimitReader(req.Reader, req.Range.Length))

Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files. Typical impact: unauthorized file read or write outside the intended directory.

Kodem intelligence

• Dragonfy v2.1.0 and above.

1. What is CVE-2025-59352? CVE-2025-59352 is a medium-severity path traversal vulnerability in github.com/dragonflyoss/dragonfly (go), affecting versions < 2.1.0. It is fixed in 2.1.0. Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files.
2. Which packages are affected by CVE-2025-59352?
   • github.com/dragonflyoss/dragonfly (go) (versions < 2.1.0)
   • d7y.io/dragonfly/v2 (go) (versions < 2.1.0)
3. Is there a fix for CVE-2025-59352? Yes. CVE-2025-59352 is fixed in 2.1.0. Upgrade to this version or later.
4. Is CVE-2025-59352 exploitable, and should I be worried? Whether CVE-2025-59352 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

5. What actually determines whether CVE-2025-59352 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
6. How do I fix CVE-2025-59352?
   • Upgrade github.com/dragonflyoss/dragonfly to 2.1.0 or later
   • Upgrade d7y.io/dragonfly/v2 to 2.1.0 or later
