Vulnerabilities 15
-
High 8.8CVE-2026-14662 Public exploit
PostgreSQL tsvector and tsquery undersize allocations, via integer wraparound
Integer wraparound in PostgreSQL tsvector and tsquery data type functions allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds, via crafted large inputs. This may execute arbitrary code as the operating s…
-
High 8.8
PostgreSQL regexp heap buffer overflow executes arbitrary code
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 this case involved un…
-
High 8.8CVE-2026-14669 Public exploit
PostgreSQL to_char heap buffer overflow executes arbitrary code
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 18.6, 17.11, 16.15, …
-
High 8.8
PostgreSQL plperl tied object heap buffer overflow executes arbitrary code
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, 16.15, 15.19, and 14.24…
-
High 8.8
PostgreSQL refint plan cache type confusion executes arbitrary code
Type confusion in PostgreSQL module "refint" allows an object creator to execute arbitrary code as the operating system user running the database. The fix for this emerged as a non-security bug report, and the fix appear in the git repository with subject "re…
-
High 8.8
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 runnin…
-
High 8.8
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-incompati…
-
High 8.8
PostgreSQL fuzzystrmatch writes effectively-arbitrary addresses, via integer wraparound
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 levenshtein_less_equal(…
-
High 8.8
PostgreSQL type confusion in cursor CLOSE + DECLARE executes arbitrary code
Type confusion in PostgreSQL "portal"/cursor lifecycle allows a user to execute arbitrary code as the operating system user running the database, via re-creation of a cursor or other portal with different types. Versions before PostgreSQL 18.6, 17.11, 16.15, …
-
High 8.8
PostgreSQL psql \unrestrict lets superuser of pg_dump origin server execute arbitrary code in psql client
Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql \restrict meta-command in…
-
High 8.8
PostgreSQL pg_dump heap buffer overflow executes arbitrary code
Heap buffer overflow in PostgreSQL pg_dump of long function transform lists allows an object creator to execute arbitrary code as the operating system user running pg_dump, via a crafted transform list. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, an…
-
High 8.2
PostgreSQL stack buffer overflow in argument match writes 0x0 and 0x1 to server memory
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 14.24 are affected.
-
High 8.1
PostgreSQL ctid type confusion in selectivity estimator discloses derivative of arbitrary read
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 calculation loses precision, …
-
High 8.1
PostgreSQL psql COPY FROM STDIN early failure processes data lines as psql commands
Untrusted data inclusion in PostgreSQL psql COPY may allow a server administrator to elicit execution of data lines as psql commands, via error injection. If the "COPY FROM STDIN" or "\copy FROM STDIN" command fails before the server indicates that it awaits …
-
High 7.2CVE-2026-6471 Public exploit
PostgreSQL logical decoding can dlopen arbitrary file
Missing authorization in PostgreSQL logical decoding allows a non-superuser holding REPLICATION privilege to dlopen any file visible to the operating system account running the server, via the choice of logical decoding plugin. This in turn runs arbitrary cod…
