CVE-2026-14662 (GCVE-0-2026-14662)

Vulnerability from cvelistv5 – Published: 2026-08-13 13:00 – Updated: 2026-08-29 23:07

Title

PostgreSQL tsvector and tsquery undersize allocations, via integer wraparound

Summary

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-2026-6473 had fixed similar problems. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.

Severity

8.8 (High)

CVE-2026-14664 (GCVE-0-2026-14664)

Vulnerability from cvelistv5 – Published: 2026-08-13 13:00 – Updated: 2026-08-29 23:07

Title

PostgreSQL regexp heap buffer overflow executes arbitrary code

Summary

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 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.

Severity

8.8 (High)

CVE-2026-14668 (GCVE-0-2026-14668)

Vulnerability from cvelistv5 – Published: 2026-08-13 13:00 – Updated: 2026-08-29 23:07

Title

PostgreSQL ctid type confusion in selectivity estimator discloses derivative of arbitrary read

Summary

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 appears possible. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.

Severity

8.1 (High)

CVE-2026-14677 (GCVE-0-2026-14677)

Vulnerability from cvelistv5 – Published: 2026-08-13 13:00 – Updated: 2026-08-29 23:07

Title

PostgreSQL 32-bit pltcl and plperl undersize allocations, via integer wraparound

Summary

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 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.

Severity

Vulnerability from cvelistv5 – Published: 2026-08-13 13:00 – Updated: 2026-08-29 23:07

Title

PostgreSQL stack buffer overflow in argument match writes 0x0 and 0x1 to server memory

Summary

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.

Severity

CVE-2026-14680 (GCVE-0-2026-14680)

Vulnerability from cvelistv5 – Published: 2026-08-13 13:00 – Updated: 2026-08-29 23:07

Title

PostgreSQL type confusion via "internal" arguments

Summary

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 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.

Severity

8.8 (High)

Title

PostgreSQL expression deparse allows SQL injection via EXTRACT argument

Summary

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 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
