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…

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…

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…

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, …

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(…

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…

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…

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…

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.

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…

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…

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 …

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…
