CVE-2026-44734: CWE-862: Missing Authorization in opf openproject
OpenProject is open-source, web-based project management software. Prior to 17.3.2 and 17.4.0, a Missing Authorization vulnerability exists in OpenProject's CostReportsController. The rename and update actions allow any authenticated user to modify the name, filters, and grouping of any Public cost report in the system without verifying ownership or permission level. An attacker who discovers or guesses a public report's numeric ID can rename or overwrite its filter configuration without any warning to the report's owner. This vulnerability is fixed in 17.3.2 and 17.4.0.

Technical Summary
CVE-2026-44734 is a missing authorization vulnerability (CWE-862) in OpenProject's CostReportsController affecting versions before 17.3.2 and 17.4.0. The vulnerability allows any authenticated user to modify the name, filters, and grouping of any public cost report without verifying ownership or permission level. Exploitation requires knowledge or guessing of the public report's numeric ID. This can lead to unauthorized modification of report configurations. The vulnerability is addressed in OpenProject versions 17.3.2 and 17.4.0.
Potential Impact
The vulnerability allows authenticated users to modify public cost reports they do not own, potentially disrupting report configurations and causing unauthorized changes. There is no confidentiality or availability impact reported, but integrity of public cost reports is compromised. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade OpenProject to version 17.3.2 or 17.4.0 or later, where this missing authorization vulnerability is fixed. Since this is not a cloud service, manual patching is required. Patch status is confirmed fixed in these versions.
