CVE-2026-67528

MEDIUMPre-NVD 4.34.3
EchelonGraph scoreLOW confidence

This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). 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).

OpenProject is open-source, web-based project management software. Prior to 17.6.0, GET /api/v3/custom_options/:id resolved CustomOption records by global numeric id and allowed UserCustomField and GroupCustomField options without checking visible(current_user), so authenticated non-admin users could enumerate sequential custom option ids and read labels belonging to admin_only user or group custom fields. This issue is fixed in 17.6.0.
