CWE
  • CWE-693 - Protection Mechanism Failure
Summary
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.

  • CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor
Summary
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.

CWE
  • CWE-202 - Exposure of Sensitive Information Through Data Queries
Summary
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.

CWE
  • CWE-789 - Memory Allocation with Excessive Size Value
Summary
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-2026-105613 (GCVE-0-2026-105613)
Vulnerability from cvelistv5
Published

CWE
  • CWE-789 - Memory Allocation with Excessive Size Value
Summary
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.

CWE
Summary
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

  • CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary
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

  • CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary
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

CWE
  • CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
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. The problem is resolved in PostgreSQL Anonymizer 3.1.1 and further versions

CVE-2026-9617 (GCVE-0-2026-9617)
Vulnerability from cvelistv5
Published

Modified
2026-05-28 03:55
CWE
  • CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary
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

CWE
  • CWE-427 - Uncontrolled Search Path Element
Summary
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

CWE
  • CWE-427 - Uncontrolled Search Path Element
Summary
PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a custom operator in the public schema and place malicious code in that operator. This operator will later be executed with superuser privileges when the extension is created. 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 if a superuser adds a new schema in her/his own search_path and grants the CREATE privilege on that schema to untrusted users, both actions being clearly discouraged by the PostgreSQL documentation. The problem is resolved in PostgreSQL Anonymizer 3.0.1 and further versions

CVE-2024-2339 (GCVE-0-2024-2339)
Vulnerability from cvelistv5
Published
2024-03-08 20:07
Modified
2024-08-02 19:53
CWE
  • CWE-20 - Improper Input Validation
Summary
PostgreSQL Anonymizer v1.2 contains a vulnerability that allows a user who owns a table to elevate to superuser. A user can define a masking function for a column and place malicious code in that function. When a privileged user applies the masking rules using the static masking or the anonymous dump method, the malicious code is executed and can grant escalated privileges to the malicious user. PostgreSQL Anonymizer v1.2 does provide a protection against this risk with the restrict_to_trusted_schemas option, but that protection is incomplete. Users that don't own a table, especially masked users cannot exploit this vulnerability. The problem is resolved in v1.3.

CVE-2024-2338 (GCVE-0-2024-2338)
Vulnerability from cvelistv5
Published

Modified
2024-08-01 19:11
CWE
  • CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary
PostgreSQL Anonymizer v1.2 contains a SQL injection vulnerability that allows a user who owns a table to elevate to superuser when dynamic masking is enabled. PostgreSQL Anonymizer enables users to set security labels on tables to mask specified columns. There is a flaw that allows complex expressions to be provided as a value. This expression is then later used as it to create the masked views leading to SQL Injection. If dynamic masking is enabled, this will lead to privilege escalation to superuser after the label is created. Users that don't own a table, especially masked users cannot exploit this vulnerability. The problem is resolved in v1.3.

PostgreSQL Anonymizer enables users to set security labels on tables to mask specified columns. There is a flaw that allows complex expressions to be provided as a value. This expression is then later used as it to create the masked views leading to SQL Injection. If dynamic masking is enabled, this will lead to privilege escalation to superuser after the label is created. Users that don\u0027t own a table, especially masked users cannot exploit this vulnerability. The problem is resolved in v1.3."
