{"id":"CVE-2024-41801","aliases":["EUVD-2024-39190","GHSA-g92v-vrq6-4fpw"],"status":"published","title":"OpenProject packaged installation has Open Redirect Vulnerability in Sign-In in default configuration","description":"OpenProject is open source project management software. Prior to version 14.3.0, using a forged HOST header in the default configuration of packaged installations and using the \"Login required\" setting, an attacker could redirect to a remote host to initiate a phishing attack against an OpenProject user's account. This vulnerability affects default packaged installation of OpenProject without any additional configuration or modules on Apache (such as mod_security, manually setting a host name, having a fallthrough VirtualHost). It might also affect other installations that did not take care to fix the HOST/X-Forwarded-Host headers. Version 14.3.0 includes stronger protections for the hostname from within the application using the HostAuthorization middleware of Rails to reject any requests with a host name that does not match the configured one. Also, all generated links by the application are now ensured to use the built-in hostname. Users who aren't able to upgrade immediately may use mod_security for Apache2 or manually fix the Host and X-Forwarded-Host headers in their proxying application before reaching the application server of OpenProject. Alternatively, they can manually apply the patch to opt-in to host header protections in previous versions of OpenProject.","severity":{"version":"3.1","score":4.7,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00337,"percentile":0.27454,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-601"],"published":"2024-07-25T16:50:16Z","modified":"2026-10-28T02:30:31Z","products":[{"vendor":"openproject","product":"openproject"},{"vendor":"opf","product":"openproject"}],"references":[{"url":"https://github.com/opf/openproject/security/advisories/GHSA-g92v-vrq6-4fpw","tags":["x_refsource_CONFIRM","x_transferred","Vendor Advisory","advisory"]},{"url":"https://github.com/user-attachments/files/16371759/host-protection.patch","tags":["x_refsource_MISC","x_transferred","Patch","web"]},{"url":"https://www.openproject.org/docs/release-notes/14-3-0","tags":["x_refsource_MISC","x_transferred","Release Notes","web"]},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/41xxx/CVE-2024-41801.json","tags":["advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2024-41801","tags":["advisory"]}],"sources":{"cve":[{"id":"CVE-2024-41801","title":"OpenProject packaged installation has Open Redirect Vulnerability in Sign-In in default configuration","description":"OpenProject is open source project management software.
