postgresql: Fix of 13 CVEs
Type: advisorySources: OSV
- CVE-2026-6464: teach psql to skip in-line data after a COPY ... FROM STDIN that fails before PGRES_COPY_IN, so the data is no longer executed as SQL - CVE-2026-6471: restrict logical decoding output plugins to the new output_plugin_libraries parameter. NOTE: this is a deliberate default-deny change, matching upstream and RHSA-2026:67491. Installations using a third-party output plugin (for example decoderbufs/Debezium) must add it to output_plugin_libraries in postgresql.conf and reload before logical replication slots can be created again. Audit with: SELECT DISTINCT plugin FROM pg_replication_slots WHERE plugin IS NOT NULL; - CVE-2026-16239: cross-check the output row type of a portal running EXECUTE or FETCH - CVE-2026-18408: do not perform backquote expansion on the argument of psql's \unrestrict command
