CVE-2026-1201524.3 MED—
———Use after free in PostgreSQL pg_show_all_settings() allows a database user to retrieve memory contents, via loading a module while the function is scanning custom-variable placeholders that the module replaces and frees. Within major versions 16-18, minor versions before PostgreSQL 18.7, 17.12, and 16.16 are affected. Versions before PostgreSQL 16 are unaffected.2hCVE-2026-1201508.8 HIG—
———Use after free in PostgreSQL expanded-record domain checks allows an object creator to execute arbitrary code as the operating system user running the database, via repeated checks of a domain over a composite type that cause reuse of a dangling memory-context pointer. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.5hCVE-2026-1201478.8 HIG—
———Use after free in the PostgreSQL dblink extension allows an object creator to execute arbitrary code as the operating system user running the database, via type conversion code that re-enters dblink and closes a connection whose results an outer dblink call is reading. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.5hCVE-2026-1201438.8 HIG—
———Use after free in PostgreSQL trigger functions allows an object creator to execute arbitrary code as the operating system user running the database, via a cursor over a transition table. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.2hCVE-2026-1163328.8 HIG—
———Use after free in PostgreSQL portal setup allows an object creator to execute arbitrary code as the operating system user running the database, via running user-defined code during planning or executor startup that closes the portal currently being prepared. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.2hCVE-2026-1163238.8 HIG—
———Use after free in PostgreSQL pltcl allows an object creator to execute arbitrary code as the operating system user running the database, via a domain CHECK that re-enters the Tcl interpreter and frees or changes a string still used by the outer result conversion. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.5h
