| CVE-2026-77151 | 1 Lin-snow | 1 Ech0 | 2026-08-20 | 3.7 Low |
| A security flaw has been discovered in lin-snow Ech0 up to 5.4.1. Affected by this issue is the function MD5Encrypt of the file internal/util/crypto/crypto.go. Performing a manipulation results in risky cryptographic algorithm. Remote exploitation of the attack is possible. The complexity of an attack is rather high. The exploitation is known to be difficult. Upgrading to version 5.4.2 can resolve this issue. The patch is named 9ce19a3b0d0765086a655f45d3a706ec1810404f. It is recommended to upgrade the affected component. | ||||
| CVE-2026-35037 | 2 Ech0, Lin-snow | 2 Ech0, Ech0 | 2026-04-22 | 7.2 High |
| Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, the GET /api/website/title endpoint accepts an arbitrary URL via the website_url query parameter and makes a server-side HTTP request to it without any validation of the target host or IP address. The endpoint requires no authentication. An attacker can use this to reach internal network services, cloud metadata endpoints (169.254.169.254), and localhost-bound services, with partial response data exfiltrated via the HTML <title> tag extraction This vulnerability is fixed in 4.2.8. | ||||
| CVE-2026-35036 | 2 Ech0, Lin-snow | 2 Ech0, Ech0 | 2026-04-15 | 7.5 High |
| Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, Ech0 implements link preview (editor fetches a page title) through GET /api/website/title. That is legitimate product behavior, but the implementation is unsafe: the route is unauthenticated, accepts a fully attacker-controlled URL, performs a server-side GET, reads the entire response body into memory (io.ReadAll). There is no host allowlist, no SSRF filter, and InsecureSkipVerify: true on the outbound client. Anyone who can reach the instance can force the Ech0 server to open HTTP/HTTPS URLs of their choice as seen from the server’s network position (Docker bridge, VPC, localhost from the process view). This vulnerability is fixed in 4.2.8. | ||||
| CVE-2026-33638 | 2 Ech0, Lin-snow | 2 Ech0, Ech0 | 2026-04-02 | 5.3 Medium |
| Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to version 4.2.0, `GET /api/allusers` is mounted as a public endpoint and returns user records without authentication. This allows remote unauthenticated user enumeration and exposure of user profile metadata. A fix is available in v4.2.0. | ||||
