-
High 8.8
PostgreSQL pg_stat_statements heap buffer overflow executes arbitrary code
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 versions before PostgreSQ…
-
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 expression deparse allows SQL injection via EXTRACT argument
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, and any similar usage…
-
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 pg_restore_attribute_stats() executes arbitrary code
Type confusion in PostgreSQL pg_restore_attribute_stats() allows an object creator to execute arbitrary code as the operating system user running the database, via conflation of range and multirange values. Within major version 18, minor versions before Postg…
-
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…
-
Medium 6.5
PostgreSQL pgcrypto, for OpenSSL-disabled ciphers, silently encrypts to and decrypts from cleartext
Cleartext storage in PostgreSQL pgcrypto disabled ciphers allows a user to recover cleartext, via direct observation of the faulty ciphertext. The OpenSSL version and OpenSSL configuration determine the disabled ciphers. If the application accepts encrypted d…
-
Medium 5.3
PostgreSQL observable response discrepancy with non-default scram_iterations provides user existence oracle
Observable response discrepancy in PostgreSQL SCRAM authentication allows an unauthenticated user to test the existence of a user via observing the SCRAM iteration count. This requires the probed user to have a non-default scram_iterations count, because the …
-
Medium 4.3
PostgreSQL pg_trgm picksplit reads past end of buffer
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 18.6, 17.11, 16.15, 15…
-
Medium 4.3
PostgreSQL ascii() function reads past end of buffer
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. Vers…
-
Medium 4.3
PostgreSQL fails to check type USAGE privilege
Missing authorization in PostgreSQL DDL commands allows an object creator to achieve denial of service against ALTER and DROP of the type, via creating a dependency on the type. Many DDL operations did check the privilege, but assigning a range subtype and re…
-
Medium 4.2
PostgreSQL row security caching disregards role modifications
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. Stale policies continu…
-
Medium 4.2
PostgreSQL improper enforcement of GSSAPI encryption when coupled with SSL
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 may exchange data o…
-
Low 3.8
PostgreSQL amcheck does not clear untrusted search path
Untrusted search path in PostgreSQL amcheck allows a grantee of amcheck function EXECUTE privilege to execute arbitrary functions as the owners of expression indexes that depend on the search path, via setting a hostile search path before calling the amcheck …
-
Low 3.8
PostgreSQL ECPG integer underflow can crash the client
Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client overwrites a huge memory region with bytes outside at…
-
Low 3.8
PostgreSQL ALTER TABLE ALTER TYPE resets extended statistics ownership
Incorrect ownership assignment in PostgreSQL ALTER TABLE ALTER TYPE command reassigns ownership of dependent statistics objects to the current user. This wrongly allows the table owner to run DROP STATISTICS and ALTER STATISTICS via this improper ownership. I…
