How to Fix CVE-2025-59352

To remediate this vulnerability, upgrade all affected Github.com/dragonflyoss/dragonfly dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/dragonflyoss/dragonfly fixed: 2.1.0
Upgrade github.com/dragonflyoss/dragonfly to 2.1.0
d7y.io/dragonfly/v2 fixed: 2.1.0
Upgrade d7y.io/dragonfly/v2 to 2.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/dragonflyoss/dragonfly

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-59352, inspect your project dependencies for Github.com/dragonflyoss/dragonfly:

inspect dependencies for github.com/dragonflyoss/dragonfly

Analyze the terminal output to locate any version of Github.com/dragonflyoss/dragonfly in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-202: Exposure of Sensitive Information Through Data Queries, where when trying to keep information confidential, an attacker can often infer some of the information by using statistics. In Github.com/dragonflyoss/dragonfly, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact 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. ```golang 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)) ``` ### Patches - Dragonfy v2.1.0 and above. ### Workarounds There are no effective workarounds, beyond upgrading. ### References A third party security audit was performed by Trail of Bits, you can see the [full report](https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf).
