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.
AI Analysis
Technical Summary
CVE-2026-44734 is a Missing Authorization (CWE-862) vulnerability 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 a 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
An attacker with authenticated access can modify public cost reports by renaming them or changing their filter configurations without permission checks. This impacts the integrity of cost reports but does not affect confidentiality or availability. There is no indication of data disclosure or denial of service. The vulnerability could cause confusion or misrepresentation of project cost data.
Mitigation Recommendations
Upgrade OpenProject to version 17.3.2 or 17.4.0 or later, where this authorization issue is fixed. Since the vendor advisory confirms the fix in these versions, applying the official update is the recommended remediation. No other mitigations are specified.
