{"id":"AZL-108189","summary":"CVE-2026-107350 affecting package pgbouncer 1.25.2-1","details":"Improper authentication in PgBouncer 1.17.0 through 1.26.0 allows a remote attacker who knows the password of a user listed in auth_file to log in as any other user that authenticates using SCRAM, including PgBouncer admin users and backend superusers. A second StartupMessage sent during SCRAM authentication against a non-existent database is not rejected and switches the user being logged in as, while the SCRAM exchange is still verified against the keys of the first user.","modified":"2026-10-15T14:17:16.450147820Z","published":"2026-10-14T18:17:25Z","upstream":["CVE-2026-107350"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107350"}],"affected":[{"package":{"name":"pgbouncer","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/pgbouncer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.25.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-108189.json"}}],"schema_version":"1.9.0"}
