CVE-2026-116314— PostgreSQL pg_restore executes arbitrary code due to missing non-plain archive validation
Quick assessment
Affected
n/a PostgreSQL
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
PostgreSQL 的 组件存在输入验证不当的漏洞。攻击者可通过构造恶意归档文件，利用非纯文本（non-plain）归档提供者，在运行 的操作系统用户权限下执行任意代码。 需要特别说明的是：虽然构造的归档数据在恢复目标处合法地触发任意 SQL 语句执行，但这并不应导致 进程本身在操作系统层面执行任意代码。受影响的版本包括 PostgreSQL 18.7 之前、17.12 之前、16.16 之前、15.20 之前以及 14.25 之前的所有版本。

Vulnerability Title
PostgreSQL pg_restore executes arbitrary code due to missing non-plain archive validation
Source: CVE Program / CVE List V5
Vulnerability Description
Improper input validation in PostgreSQL pg_restore allows a non-plain archive provider to execute arbitrary code as the operating system user running pg_restore, via a crafted archive. Note a contrast: crafted archive data may legitimately cause arbitrary SQL to execute at the restore destination, but it does not legitimately confer arbitrary code execution in the pg_restore OS process. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
