Because the apply worker runs at a privilege level equivalent to a PostgreSQL superuser in default installations, any function invoked by such a default expression also runs at that privilege. A party acting as the publisher can use this path to cause functions to be executed on the subscriber as superuser, escalating from a role permitted to use pglogical to full superuser.\n\nThis is a second, independent path to the same superuser escalation tracked under CVE-2026-50736 (the pglogical queue issue). To exploit the issue an attacker must be able to direct a subscription at an endpoint they control. In default installations this requires privileges normally reserved for a superuser, so the issue is most relevant to managed deployments where the ability to create subscriptions has been delegated to non-superuser roles." } ], "metrics": [ { "format": "CVSS", "cvssV4_0": { "version": "4.0", "attackVector": "NETWORK", "attackComplexity": "HIGH", "attackRequirements": "PRESENT", "privilegesRequired": "LOW", "userInteraction": "NONE", "vulnConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "HIGH", "subIntegrityImpact": "HIGH", "subAvailabilityImpact": "HIGH", "baseScore": 9, "baseSeverity": "CRITICAL", "vectorString": "CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H" } } ], "credits": [ { "lang": "en", "value": "Mehmet Ince (@mdisec)", "type": "finder" } ], "source": { "discovery": "EXTERNAL" }, "references": [ { "url": "https://www.enterprisedb.com/docs/security/advisories/cve202650737/" } ] }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-07-28T18:48:38.115237Z", "id": "CVE-2026-50737", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-07-28T18:52:19.292Z" } } ] } }
