CVE-2026-110181

PostgreSQL Anonymizer: Function declared with SQL-standard syntax leak anonymized data

PostgreSQL Anonymizer contains a vulnerability related to anonymization functions defined using SQL-standard function bodies. PostgreSQL analyses such functions at declaration time, while Anonymizer only attempts to check them at execution time. This problem can be exploited by any user with the TEMPORARY privilege. The issue is fixed in PostgreSQL Anonymizer 3.3.0 and later versions.

CVE-2026-105613

PostgreSQL Anonymizer: Unbounded memory allocation (DoS) in range-based dummy functions

PostgreSQL Anonymizer's range-based dummy functions dont constraint the range size. This vulnerability can be exploited to exhaust the memory of a backend and OOM-kill it (when ovecommit is on), which results in a cluster-wide crash recovery. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.

PostgreSQL Anonymizer: Unbounded image-decode memory allocation (DoS) in anon.image_blur()

PostgreSQL Anonymizer's `anon.image_blur()` function doesn't check the declared dimension of the provided image, allowing an attacker to provide a small image with enormous declared dimensions. This vulnerability can be exploited to exhaust the memory of a backend and OOM-kill it (when ovecommit is on), which results in a cluster-wide crash recovery. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.

CVE-2026-105615

PostgreSQL Anonymizer: Masked roles can read the statistics of masked columns in pg_stats

PostgreSQL's optimized statistics on a table are visible as long as you have SELECT privilege on said table. A masked role can therefore read a limited subset of the data through the statistics view's histograms and mcvs. The vulnerability is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.

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

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.

PostgreSQL Anonymizer: Cached plans bypass transparent dynamic masking after a role change or a new masking rule

PostgreSQL Anonymizer doesn't invalidate plans prepared after a rule was added or a role changed. Users using such plans can still see the unmasked data until the end of the session. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.

PostgreSQL Anonymizer: RESTRICTED functions are reachable through a subLink

PostgreSQL Anonymizer contains a vulnerability that allows unprivileged masked users to repeatedly call the anon.hash() function and collects (seed, hash_output) pairs to perform an offline brute-force attack and deduce the salt. A masked role can run a RESTRICTED function when the call is placed inside the sub-select. The problem is resolved in PostgreSQL Anonymizer 3.2.3 and later versions

PostgreSQL Anonymizer: SQL injection in import_database_rules() and import_roles_rules() via crafted object names / JSON

PostgreSQL Anonymizer contains a SQL injection vulnerability in two import functions. A user can create a malicious JSON document containing specially crafted object names. If a superuser subsequently calls anon.import_database_rules() or anon.import_roles_rules(), the malicious code is executed with superuser privileges. The issue is fixed in PostgreSQL Anonymizer 3.1.4 and later

PostgreSQL Anonymizer: unprivileged masked users can execute code via operators, domain casts and view subqueries

PostgreSQL Anonymizer contains a vulnerability that allows unprivileged masked users to execute arbitrary code by abusing operators, domain casts, or view subqueries that carry untrusted expressions. When these objects are evaluated in the context of the extension’s masking mechanisms, the malicious code can run with elevated privileges. The issue is fixed in PostgreSQL Anonymizer 3.1.4 and later versions

PostgreSQL Anonymizer: SQL injection in the rules import functions

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.

CVE-2026-9617

PostgreSQL Anonymizer: malicious column name allows SQL injection via anon.k_anonymity() function

PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a table and placing malicious code inside a column identifier. If a superuser calls the k-anonymity function, the malicious code is executed with superuser privileges. The risk is higher with PostgreSQL 14 or with instances upgraded from PostgreSQL 14 or a prior version. With PostgreSQL 15 and later, the creation permission on the public schema is revoked by default and this exploit can only be achieved by a user who was explicitly granted the CREATE TABLE privilege. The problem is resolved in PostgreSQL Anonymizer 3.1.0 and further versions

Improper search_path protection in PostgreSQL Anonymizer 2.5 allows any user with create privilege to gain superuser privileges

PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a temporary view based on a function containing malicious code. When the anon.get_tablesample_ratio function is then called, the malicious code is executed with superuser privileges. This privilege elevation can be exploited by users having the CREATE privilege in PostgreSQL 15 and later. The risk is higher with PostgreSQL 14 or with instances upgraded from PostgreSQL 14 or a prior version because the creation permission on the public schema is granted by default. The problem is resolved in PostgreSQL Anonymizer 3.0.1 and further versions
