CVE-2026-105616— PostgreSQL Anonymizer: The secret salt and shift of anon are readable by any role in pg_roles or pg_db_role_setting

Quick assessment

Affected

DALIBO PostgreSQL Anonymizer

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 通过命令限制了非角色成员对盐值（salt）和偏移量（shift）的访问。然而，如果这些参数是在数据库、用户或两者上设置的，它们仍可通过或系统视图被查看到。PostgreSQL Anonymizer 的文档建议使用或来设置盐值。该问题已在 PostgreSQL Anonymizer 3.3.0 及更高版本中得到修复。

Vulnerability Title

PostgreSQL Anonymizer: The secret salt and shift of anon are readable by any role in pg_roles or pg_db_role_setting

Source: CVE Program / CVE List V5

Vulnerability Description

PostgreSQL restricts acces to the salt and shift via the `SHOW` command for users not member of `pg_read_all_settings`. But they are visible in `pg_db_role_setting` or `pg_roles` if they were set on the database, user or both. PostgreSQL Anonymizer's documentation recommends to use ALTER DATABASE / ALTER ROLE for the salt. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.
