{"schema":"threatline.record/2","record":{"id":"CVE-2026-107349","aliases":[],"summary":"Infinite loop on empty option name in startup options parameter in PgBouncer","details":"An infinite loop in PgBouncer 1.20.0 through 1.26.0 allows an unauthenticated remote attacker to cause a denial of service. A StartupMessage whose options parameter contains an empty parameter name, such as \"-c=\", makes the ignore_startup_parameters list lookup loop forever. Because PgBouncer serves all clients from a single process, this saturates a CPU core and makes PgBouncer unresponsive to all clients until the process is restarted.","categories":["Unclassified"],"product":"PgBouncer","vendor":"n/a","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107349","source_modified_at":"2026-10-16T20:19:16.649Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"PgBouncer","vendor":"n/a","versions":[{"version":"1.20.0","lessThan":"1.26.1","versionType":"semver","status":"affected"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107349","source_modified_at":"2026-10-16T20:19:16.649Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"PgBouncer","ecosystem":null},"version":"1.26.1","basis":"first unaffected version stated in the CVE record"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00422,"percentile":0.35432,"score_date":"2026-10-23"},"published_at":"2026-10-14T17:34:33.785Z","modified_at":"2026-10-16T20:19:16.649Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107349","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T20:19:16.649Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107349","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.pgbouncer.org/changelog.html"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-16T20:19:04.558160Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T20:19:16.649Z","content_hash":"2d9be81b5e04af2fe51deda9aa2a97345f53921d1cabaca7cce2bca772b97e01"}}
