CVE-2026-44734 | OpenProject is open-source, web-based project management sof… | CVSS 6.5 MEDIUM

Description

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.
