Summary
PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a JSON document and placing malicious code inside a particular key-value pair. If a superuser calls the import_database_rules() or import_roles_rules() functions, the malicious code is executed with superuser privileges.
Risk Assessment
This vulnerability poses a serious risk to system security, allowing unauthorized users to gain full access to the database. This could lead to unauthorized access to and modification of data.
Recommendation
It is recommended to update PostgreSQL Anonymizer to version 3.1.1 or later to mitigate this vulnerability. Additionally, conduct an audit of user permissions and monitor calls to import functions.
Other vulnerabilities in PostgreSQL Anonymizer
See all- CVE-2026-83534Medium
PostgreSQL Anonymizer contains a vulnerability in the anon.anonymize_database_parallel() function that allows a table owner to execute arbitrary code with superuser privileges. The issue is fixed in version 3.2.0 and later.
- CVE-2026-19634Medium
PostgreSQL Anonymizer contains a SQL injection vulnerability in two import functions. A user can create a malicious JSON document with specially crafted object names.

- CVE-2026-19633High
PostgreSQL Anonymizer contains a vulnerability allowing unprivileged masked users to execute arbitrary code by abusing operators, domain casts, or view subqueries carrying untrusted expressions. When evaluated in the masking context, malicious code can run with elevated privileges. Fixed in version 3.1.4 and later.
- CVE-2026-13455Medium
A vulnerability in PostgreSQL Anonymizer allows unprivileged masked users to repeatedly call the anon.hash() function and collect (seed, hash_output) pairs to perform an offline brute-force attack and deduce the salt.
