CVE-2026-18024

Buffer over-read in PostgreSQL ascii SQL function allows a user to disclose up to 3 bytes after the end of a specific allocation, via a crafted text value. This is the same class of defect that CVE-2026-2006 fixed, though this instance has less impact. Versions before PostgreSQL 18.5, 17.11, 16.1...

CVE-2026-15742

The CVE affects PostgreSQL using the fuzzystrmatch extension. A vulnerability in integer wraparound in fuzzystrmatch allows an attacker to direct writes to a very large address range, enabling arbitrary code execution as the OS user running the database, via extreme inputs to levenshtein() or lev...

CVE-2026-14680 PostgreSQL type confusion via "internal" arguments

Type confusion with PostgreSQL "internal" data type arguments allows any user to execute arbitrary code as the operating system user running the database, via calls to functions with that argument type. Type "internal" represents a class of mutually-incompatible data structures not intended for...

CVE-2026-14678 PostgreSQL pg_trgm picksplit reads past end of buffer

Buffer over-read in PostgreSQL pgtrgm index picksplit function reads past end of a heap buffer. This might allow a table maintainer to infer limited memory values, via the lossy signal of index split choices. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected...

CVE-2026-14677 PostgreSQL 32-bit pltcl and plperl undersize allocations, via integer wraparound

Integer wraparound in PostgreSQL 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This may execute arbitrary code as the operating system user running the database. CVE-2026-6473 had fixe...
