CVE-2026-18408: Inclusion of Functionality from Untrusted Control Sphere

Untrusted data inclusion in pgdump 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 input expansion. The fix for CVE-2025-871...

CVE-2026-6464: Inclusion of Functionality from Untrusted Control Sphere

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 input rows, psql processes the in-line...

CVE-2026-14668: Access of Resource Using Incompatible Type

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, substantial memory value recovery...

CVE-2026-14679: Stack-based Buffer Overflow

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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected...

CVE-2026-15742: Integer Overflow or 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 levenshteinlessequal. Versions before PostgreSQL 18.5, 17.11,...

CVE-2026-14664: Heap-based Buffer Overflow

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 unanticipated data growth when...

CVE-2026-6471: Missing Authorization

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 code as that account. Versions before...

CVE-2026-14672: Observable Response Discrepancy

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 scramiterations count, because the authentication challenge for a...

CVE-2026-14678: Buffer Over-read

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-2026-14666: Improper Preservation of Consistency Between Independent Representations of Shared State

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 continue until some other event invalidates t...

CVE-2026-14681: Improper Enforcement of Message Integrity During Transmission in a Communication Channel

Improper enforcement of message integrity in PostgreSQL GSSAPI support allows a user to negotiate GSSAPI contrary to pghba.conf rules, via initial direct TLS connection. Despite a pghba.conf that appears to require GSSAPI, the connection may exchange data over TLS encryption alone. If the TLS...

CVE-2026-16241: Integer Underflow (Wrap or Wraparound)

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 attacker knowledge or control. This...
