AI-suggested

Organizations should immediately upgrade OpenProject installations to versions 16.6.9, 17.0.6, 17.1.3, or 17.2.1, which contain the necessary fixes to properly escape filenames and prevent XSS injection. If you cannot patch yet, restrict push access to trusted users only and monitor repository commits for suspicious filenames containing HTML or script tags. Implement web application firewalls (WAFs) with rules to detect and block XSS payloads in repository-related HTTP responses. Educate developers and project members about the risks of opening repository pages with untrusted content. Employ Content Security Policy (CSP) headers to limit script execution scope and reduce impact of potential XSS. Regularly audit user permissions and enforce strong authentication mechanisms to reduce risk of compromised accounts. Finally, monitor logs and user activity for signs of exploitation or anomalous behavior related to repository commits.

Description

CVE-2026-32703 is a critical persistent cross-site scripting (XSS) vulnerability in the OpenProject web-based project management software affecting multiple versions prior to 16.6.9, 17.0.6, 17.1.3, and 17.2.1. The flaw exists in the Repositories module where filenames from commits are not properly escaped, allowing attackers with push access to inject malicious HTML/JavaScript code.
