Descrição técnica

Wasmtime 47.0.0 before 48.0.8, 49.0.0 before 49.0.5, and 50.0.0 before 50.0.1 contains a cross-engine type confusion vulnerability because StructType::with_finality_and_supertype does not validate that the supplied supertype belongs to the same Engine. Embedders using multiple engines that create a GC struct type with another engine's supertype can trigger runtime panics or GC heap corruption, causing denial of service; guest WebAssembly cannot trigger it.

——0Type confusion in PostgreSQL allows an object creator to execute arbitrary code as the operating system user running the database, via ALTER ... SET DATA TYPE primarily. Other DDL attack routes exist, such as "ALTER TABLE ... ADD COLUMN; ROLLBACK; ALTER TABLE ... ADD COLUMN". The system had inadequate tracking of typed values, and values were not self-identifying. Stale values could appear in data dictionary entries, PL/pgSQL variables, and many other parts of the system. PostgreSQL Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.20h CVE-2026-184478.8 ALT

——0Type confusion in PostgreSQL plpgsql record-field assignment allows an object creator to execute arbitrary code as the operating system user running the database, via a reentrant domain CHECK that changes a RECORD variable's row type while a value is being cast. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.20h CVE-2026-1201488.1 ALT

——0Type confusion in PostgreSQL extended statistics allows an object creator to execute arbitrary code as the operating system user running the database, via a statistics expression of an anonymous RECORD type whose backend-local type identifier denotes a different row type in another session. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.5h CVE-2026-1201448.8 ALT

——0Type confusion from incomplete PostgreSQL type-cache invalidation allows an object creator to execute arbitrary code as the operating system user running the database, via a composite type change while its cache entry is being populated. Within major version 18, minor versions before PostgreSQL 18.7 are affected. Versions before PostgreSQL 18 are unaffected.20h CVE-2026-1201428.8 ALT

——0Type confusion in PostgreSQL anonymous RECORD types allows an object creator to execute arbitrary code as the operating system user running the database, via row types having dropped attributes in the same positions but with different widths or alignments. Within major versions 17-18, minor versions before PostgreSQL 18.7 and 17.12 are affected. Versions before PostgreSQL 17 are unaffected.20h
