## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 9.3
- **Public exploit available:** Yes
- **Affected products:** Gorse-io Gorse
- **Weaknesses:** CWE-306 (Missing Authentication for Critical Function)
- **Tags:** go, web_application

## Description

Gorse before 0.5.10 contains an authentication bypass vulnerability in the /api/dump and /api/restore endpoints that allows unauthenticated attackers to access protected functionality when admin_api_key is empty, which is the default configuration. Remote attackers can exfiltrate the entire database including user records, items, and feedback data containing personally identifiable information, or completely overwrite the dataset without authentication.

## CrowdSec analysis

[CVE-2026-56782](https://euvd.enisa.europa.eu/vulnerability/CVE-2026-56782) is a critical authentication bypass vulnerability in Gorse versions before 0.5.10, affecting the `/api/dump` and `/api/restore` endpoints when the default empty `admin_api_key` configuration is used. Unauthenticated remote attackers can exfiltrate the entire database, including personally identifiable user, item, and feedback data, or overwrite datasets, potentially causing data breaches, integrity loss, and service disruption.

CrowdSec has been tracking this vulnerability and its exploits since 23rd of July 2026.

CrowdSec has not observed any significant exploitation activity targeting CVE-2026-56782 across its network. As a result, no community-driven trend analysis is available for this vulnerability at this time.

Attackers target the Gorse `/api/dump` endpoint to bypass authentication and retrieve the database when the `admin_api_key` is empty. Exploitation typically follows identification of a Gorse instance through the root page and uses an unauthenticated `GET` request that returns an octet-stream database dump.
