OpenProject is open-source, web-based project management software. Prior to 17.6.0, GET /api/v3/time_entries and GET /api/v3/cost_entries rendered _links.workPackage.title and _links.workPackage.href through associated_resource in modules/costs/lib/api/v3/time_entries/time_entry_representer.rb and modules/costs/lib/api/v3/cost_entries/cost_entry_representer.rb without checking WorkPackage.visible or view_work_packages, allowing users with view_time_entries or view_cost_entries to read private work package subjects and ids. This issue is fixed in 17.6.0.

MEDIUMPre-NVD 4.34.3—Trending — 3 sources updated this week
EchelonGraph scoreMEDIUM confidence
This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 85% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
