CVE-2026-31974
3.0 · LOWOverview
CVE-2026-31974 is a low-severity vulnerability affecting openproject openproject. It was published on March 11, 2026 and has a CVSS 3.1 base score of 3.0 (LOW).
This vulnerability has a CVSS 3.1 base score of 3.0, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
OpenProject is an open-source, web-based project management software. Prior to 17.2.0, OpenProject SMTP test endpoint (POST /admin/settings/mail_notifications) accepts arbitrary host and port values and exhibits measurable differences in response behaviour depending on whether the target IP exists and whether the port is open. An attacker with access can use these timing and error distinctions to map internal hosts and identify which services/ports are reachable. Similarly, you can create webhooks in OpenProject and point them to arbitrary IPs, resulting in the same kind of SSRF issue which allows attackers to scan the internal network. This vulnerability is fixed in 17.2.0.
Remediation
Check the references section for vendor advisories and patches from openproject. Update openproject to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
