An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL data sources are affected.

In the current development version of Eclipse aeriOS, for which no official release has yet been published, the Identity Manager (IdM) deployment included insecure default configurations and credentials for security-sensitive services.

The Helm chart exposed the Keycloak service and its PostgreSQL backing database through Kubernetes NodePort services by default, while the Docker Compose deployment similarly exposed PostgreSQL on all network interfaces. The deployment included fixed default credentials for the Keycloak administrator and PostgreSQL database user, and the previous Helm chart configuration did not provide adequate secret management for these credentials. In addition, predefined application users with known credentials were provided for development and testing without sufficiently warning operators against their use in production environments.

An attacker able to reach the exposed services could use the published default credentials to obtain administrative access to the Identity Manager or direct access to its database. This could allow unauthorized access to or modification of identity-management data, including users, roles, client credentials, sessions, and cryptographic material, and could enable the creation of privileged identities or tokens accepted by other aeriOS components.

The issue has been addressed by generating a random Keycloak administrator password by default, managing Keycloak and PostgreSQL credentials through Kubernetes Secrets, and restricting PostgreSQL to an internal service in both the Helm chart and Docker Compose deployment. OpenLDAP is also restricted to an internal service. The predefined users intended for development and testing are retained, but the documentation now explicitly warns that their default credentials must not be used in production and that these users should be removed or their credentials changed after installation.

https://www.postgresql.org/about/news/postgresql-175-169-1513-1418-and-1321-released-3072/ announces the release of PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21, all of which include a fix for:

CVE-2025-4207: PostgreSQL GB18030 encoding validation can read one byte past end of allocation for text that fails validation

CVSS v3.1 Base Score: 5.9

Supported, Vulnerable Versions: 13 - 17.

A buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to achieve temporary denial of service on platforms where a 1-byte over-read can elicit process termination.

This affects the database server and also libpq.

Versions before PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 are affected.

The snprintf implementation in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 does not properly handle system-call errors, which allows attackers to obtain sensitive information or have other unspecified impact via unknown vectors, as demonstrated by an out-of-memory error.

Improper neutralization of quoting syntax in PostgreSQL libpq functions PQescapeLiteral(), PQescapeIdentifier(), PQescapeString(), and PQescapeStringConn() allows a database input provider to achieve SQL injection in certain usage patterns. Specifically, SQL injection requires the application to use the function result to construct input to psql, the PostgreSQL interactive terminal. Similarly, improper neutralization of quoting syntax in PostgreSQL command line utility programs allows a source of command line arguments to achieve SQL injection when clientencoding is BIG5 and serverencoding is one of EUCTW or MULEINTERNAL. Versions before PostgreSQL 17.3, 16.7, 15.11, 14.16, and 13.19 are affected.

If PostgreSQL is configured with LDAP authentication, and your LDAP configuration allows anonymous binds, it is possible for a user to authenticate themselves with an empty password.

Affected versions: 8.3, 8.2

Fixed in versions: 8.3.8, 8.2.14

Severity: A - A vulnerability that is exploitable for privilege escalation without requiring a prior login.

A security flaw was found in the way DES and extended DES based crypt() password encryption function performed encryption of certain keys, when the key to be encrypted was provided in the Unicode encoding (certain keys were truncated before being DES digested). When the resulting ciphertext for such a previously shortened key was used as a pattern in a password protected resource, intended to be matched against subsequently encrypted value of the password field, retrieved from the user authentication dialog, it could lead to authentication bypass.

PostgreSQL 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 truncates the common name to only 32 characters when verifying SSL certificates, which allows remote attackers to spoof connections when the host name is exactly 32 characters.

PostgreSQL 9.2.x before 9.2.4, 9.1.x before 9.1.9, 9.0.x before 9.0.13, and 8.4.x before 8.4.17, when using OpenSSL, generates insufficiently random numbers, which might allow remote authenticated users to have an unspecified impact via vectors related to the "contrib/pgcrypto functions."

PostgreSQL 9.2.x before 9.2.4 and 9.1.x before 9.1.9 does not properly check REPLICATION privileges, which allows remote authenticated users to bypass intended backup restrictions by calling the (1) pgstartbackup or (2) pgstopbackup functions.

PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 allows remote authenticated users to obtain sensitive column values by triggering constraint violation and then reading the error message.

Multiple stack-based buffer overflows in json parsing in PostgreSQL before 9.3.x before 9.3.10 and 9.4.x before 9.4.5 allow attackers to cause a denial of service (server crash) via unspecified vectors, which are not properly handled in (1) json or (2) jsonb values.

Double free vulnerability in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 allows remote attackers to cause a denial of service (crash) by closing an SSL session at a time when the authentication timeout will expire during the session shutdown sequence.

contrib/pgcrypto in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 uses different error responses when an incorrect key is used, which makes it easier for attackers to obtain the key via a brute force attack.

PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 does not properly handle errors while reading a protocol message, which allows remote attackers to conduct SQL injection attacks via crafted binary data in a parameter and causing an error, which triggers the loss of synchronization and part of the protocol message to be treated as a new message, as demonstrated by causing a timeout or query cancellation.

The tochar function in PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 allows remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a (1) large number of digits when processing a numeric formatting template, which triggers a buffer over-read, or (2) crafted timestamp formatting template, which triggers a buffer overflow.

Stack-based buffer overflow in the printf function implementations in PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1, when running on a Windows system, allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a floating point number with a large precision, as demonstrated by using the tochar function.

Multiple buffer overflows in contrib/pgcrypto in PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 allow remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.

It was found that PostgreSQL client programs mishandle database and role names containing newlines, carriage returns, double quotes, or backslashes. By crafting such an object name, roles with the CREATEDB or CREATEROLE option could escalate their privileges to superuser when a superuser next executes maintenance with a vulnerable program. Vulnerable programs include pgdumpall, pgupgrade, vacuumdb, reindexdb, and clusterdb.

It was discovered that certain SQL statements containing CASE/WHEN commands could crash the PostgreSQL server, or disclose a few bytes of server memory, potentially leading to arbitrary code execution.
