CVE-2026-14673 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 function. Within major versions 18, 16...

CVE-2026-14672

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-2026-14672

CVE-2026-14672 describes an observable response discrepancy in PostgreSQL SCRAM authentication that can let an unauthenticated user infer the existence of a target user by observing the SCRAM iteration count. The issue requires the probed user to have a non-default scram_iterations value, since a...

CVE-2026-14668

The CVE concerns PostgreSQL: a type confusion in the ctid data type selectivity estimator allows an object creator to observe a calculation derived from an arbitrary 4-byte span of memory. The flaw can yield substantial memory value recovery (precision loss occurs). Affected versions are PostgreS...

CVE-2026-14669 PostgreSQL to_char heap buffer overflow executes arbitrary code

Heap buffer overflow in PostgreSQL tochartimestamptz 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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected...
