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"}}]}}
