PostgreSQL 18 Support: Frequently Asked Questions
Is the PostgreSQL 18 still supported?
Yes. The PostgreSQL 18 is currently supported by PostgreSQL, and third-party support is available as an alternative — issue management, vulnerability remediation, and compliance help independent of the vendor contract.
When is the PostgreSQL 18 end of service life (EOSL) date?
PostgreSQL lists the end of service life for the PostgreSQL 18 as Nov 14, 2030.
Can I keep using the PostgreSQL 18 after its EOSL date?
Yes. EOSL means PostgreSQL stops issuing patches and support — the software itself keeps running. Third-party support covers it from there: issue management, security vulnerability remediation, and the compliance documentation auditors ask for, for as long as you choose to run it.
How much does third-party support for the PostgreSQL 18 cost?
Typically 40-70% below the OEM maintenance renewal price. Exact pricing depends on quantity, service level and location — request a quote and we respond within 24 hours.

45 published CVEs affect the PostgreSQL 18, including 28 rated critical or high severity. Our 24/7 engineers help you assess exposure, prioritize fixes and apply available patches.
| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2026-19385 | HIGH | 8.8 | Aug 13, 2026 | 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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-18408 | HIGH | 8.8 | Aug 13, 2026 | 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 input expansion. The fix for CVE-2025-8714 introduced \restrict and \unrestrict to block this attack, but \unrestrict itself was sufficient for an attack. pg_dumpall is also affected. pg_restore is affected when used to generate a plain-for |
| CVE-2026-16239 | HIGH | 8.8 | Aug 13, 2026 | 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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-16238 | HIGH | 8.8 | Aug 13, 2026 | 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 PostgreSQL 18.5 are affected. Versions before PostgreSQL 18 are unaffected. |
| CVE-2026-15742 | HIGH | 8.8 | Aug 13, 2026 | 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(). Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-15741 | HIGH | 8.8 | Aug 13, 2026 | 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 in non-core tools. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-14680 | HIGH | 8.8 | Aug 13, 2026 | 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-incompatible data structures not intended for access from SQL. The system intended to prevent such function calls, but this prevention had gaps. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-14677 | HIGH | 8.8 | Aug 13, 2026 | 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 running the database. CVE-2026-6473 had fixed similar problems. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-14676 | HIGH | 8.8 | Aug 13, 2026 | 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 PostgreSQL 18.5 are affected. Versions before PostgreSQL 18 are unaffected. |
| CVE-2026-14671 | HIGH | 8.8 | Aug 13, 2026 | 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 "refint: Remove plan cache.", without a CVE number. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-14670 | HIGH | 8.8 | Aug 13, 2026 | 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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-14669 | HIGH | 8.8 | Aug 13, 2026 | 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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-14664 | HIGH | 8.8 | Aug 13, 2026 | 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 round-tripped through pg_wchar. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. |
| CVE-2026-14662 | HIGH | 8.8 | Aug 13, 2026 | 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 system user running the database. These types are typically sourced from application logic, not taken from the application's user. Hence, application users attacking the database, through the application as a conduit, are unlikely. CVE-20 |
| CVE-2026-6637 | HIGH | 8.8 | May 14, 2026 | Stack buffer overflow in PostgreSQL module "refint" allows an unprivileged database user to execute arbitrary code as the operating system user running the database. A distinct attack is possible if the application declares a user-controlled column as a "refint" cascade primary key and facilitates user-controlled updates to that column. In that case, a SQL injection allows a primary key update value provider to execute arbitrary SQL as the database user performing the primary key update. Vers |
| CVE-2026-6477 | HIGH | 8.8 | May 14, 2026 | Use of inherently dangerous function PQfn(..., result_is_int=0, ...) in PostgreSQL libpq lo_export(), lo_read(), lo_lseek64(), and lo_tell64() functions allows the server superuser to overwrite a client stack buffer with an arbitrarily-large response. Like gets(), PQfn(..., result_is_int=0, ...) stores arbitrary-length, server-determined data into a buffer of unspecified size. Because both the \lo_export command in psql and pg_dump call lo_read(), the server superuser can overwrite pg_dump or |
| CVE-2026-6475 | HIGH | 8.8 | May 14, 2026 | Symlink following in PostgreSQL pg_basebackup plain format and in pg_rewind allows an origin superuser to overwrite local files, e.g. /var/lib/postgres/.bashrc, that hijack the operating system account. It will remain the case that starting the server after these commands implicitly trusts the origin superuser, due to features like shared_preload_libraries. Hence, the attack has practical implications only if one takes relevant action between these commands and server start, like moving the fi |
| CVE-2026-6473 | HIGH | 8.8 | May 14, 2026 | Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. |
| CVE-2026-2006 | HIGH | 8.8 | Feb 12, 2026 | Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. |
| CVE-2026-2005 | HIGH | 8.8 | Feb 12, 2026 | Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected. |
