Common Vulnerabilities and Exposures (CVE)
CVE-2026-15742
Integer wraparound in PostgreSQL fuzzystrmatch allows a user to direct writes to a huge range of addresses, executing arbitrary code as the operating system user running the database, via extreme inputs to SQL function levenshtein() or leve...
CVE-2026-15741
SQL injection in PostgreSQL EXTRACT() deparse allows an object owner to execute arbitrary SQL as a superuser via a hostile object definition. Attacks affect expression deparse consumers broadly, including pg_dump, psql commands like \sf, a...
CVE-2026-14681
Improper enforcement of message integrity in PostgreSQL GSSAPI support allows a user to negotiate GSSAPI contrary to pg_hba.conf rules, via initial direct TLS connection. Despite a pg_hba.conf that appears to require GSSAPI, the connection...

CVE-2026-14679
Stack buffer overflow in PostgreSQL argument name matching allows an object creator to achieve unknown impacts via OUT parameter count. The attack can write only 0x0 and 0x1 bytes. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and...
CVE-2026-14678
Buffer over-read in PostgreSQL pg_trgm 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 1...
CVE-2026-14677
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 operatin...
CVE-2026-14676
Heap buffer overflow in PostgreSQL pg_stat_statements allows the query author to execute arbitrary code as the operating system user running the database, via crafted queries containing array constants. Within major version 18, minor versi...
CVE-2026-14673

CVE-2026-14670
Heap buffer overflow in PostgreSQL plperl return of a tied hash allows the function owner to execute arbitrary code as the operating system user running the database, via a crafted function body. Versions before PostgreSQL 18.6, 17.11, 16....
CVE-2026-14669
Heap buffer overflow in PostgreSQL to_char(timestamptz) allows the party choosing the timezone to execute arbitrary code as the operating system user running the database, via a long POSIX timezone abbreviation. Versions before PostgreSQL ...
CVE-2026-14668
Type confusion regarding input of PostgreSQL ctid data type selectivity estimator allows an object creator to view a calculation derived from the value of an arbitrary 4-byte span of memory, via a chosen non-ctid input. While the calculati...
CVE-2026-14666
Incomplete tracking in PostgreSQL of changes to role membership, role attributes, and database ownership allows a query to continue using cached row-level security policies after those changes require a different policy, via plan reuse. St...
CVE-2026-14664
Heap buffer overflow in PostgreSQL regexp allows the query author to execute arbitrary code as the operating system user running the database, via text that would not pass encoding validation. This shares heritage with CVE-2026-2006, but t...
