MariaDB server is a community developed fork of MySQL server. From 12.3.1 until 12.3.3 and 13.0.2, SYS_REFCURSOR handling is affected because cursor-array reallocation can leave stale references in routine contexts. A low-privileged attacker can open a large number of SYS_REFCURSORs and then fetch one to trigger a use-after-free that can enable remote code execution when combined with another vulnerability. This issue is fixed in versions 12.3.3 and 13.0.2.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3311 advisory.

    MariaDB server is a community developed fork of MySQL server. From 10.11.1 until 10.11.19, 11.4.13,     11.8.9, 12.3.3, and 13.0.2, ALTER TABLE ... CONVERT ... PARTITION does not apply filename encoding to     user-specified partition names before using them in filesystem path construction. An authenticated     database user can use a partition name requiring filename escaping to make the conversion operate on table     files the user is not authorized to access, allowing unauthorized table reads or modifications. This issue     is fixed in versions 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-102523)

    A flaw was found in MariaDB. An authenticated user with permission to use the CONNECT storage engine can     exploit an incorrect boundary check when handling DOS table types to write beyond the allocated stack     buffer. This flaw could lead to arbitrary code execution or cause the database server to crash, resulting     in a Denial of Service (DoS). (CVE-2026-107815)

    MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,     11.4.13, 11.8.9, 12.3.3, and 13.0.2, the qc_info plugin could be confused by a query containing embedded     null bytes. Reading information_schema.query_cache_info after such a query was cached could access data     beyond the end of a heap-allocated buffer, potentially disclosing adjacent memory or crashing the server.
    This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-107816)

    MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,     11.4.13, 11.8.9, 12.3.3, and 13.0.2, the mysql_json plugin assumed that imported MySQL tables contained     valid MySQL binary JSON data. A specially prepared MySQL table containing invalid JSON data could cause     out-of-bounds reads, information disclosure, or a server crash. This issue is fixed in versions 10.6.28,     10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-107817)

    MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,     11.4.13, 11.8.9, 12.3.3, and 13.0.2, MariaDB insufficiently validated counts, offsets, lengths, and field     boundaries in FRM metadata while opening binary FRM files. An attacker able to place a crafted FRM file in     the data directory could trigger out-of-bounds reads or writes, crash the server, or potentially execute     code. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
    (CVE-2026-107821)

    MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,     11.4.13, 11.8.9, 12.3.3, and 13.0.2, MariaDB's ACL cache could generate the same database-privilege cache     key for role and localhost user names that matched because both used an empty IP component. An attacker     with CREATE USER could create the colliding principal and, when the original principal's database     privileges were cached, exercise privileges assigned to the other account. This issue is fixed in versions     10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-107822)

    MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,     11.4.13, 11.8.9, 12.3.3, and 13.0.2, the MariaDB view FRM parser did not safely encode embedded newline     characters in a username. An account with CREATE USER and CREATE VIEW WITH GRANT OPTION could create a     crafted username containing additional view metadata, causing the parser to interpret part of the username     as security metadata and potentially escalating database privileges. This issue is fixed in versions     10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-107823)

    A flaw was found in MariaDB. An authenticated database user can exploit an out-of-bounds read     vulnerability by supplying a specially crafted spatial geometry to the ST_Area function. This issue allows     reading beyond allocated memory buffers, leading to unauthorized information disclosure of internal     process memory. An attacker could use this disclosed data to facilitate further attacks, such as bypassing     security protections like Address Space Layout Randomization (ASLR). (CVE-2026-85745)

    MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,     11.4.13, 11.8.9, 12.3.3, and 13.0.2, ST_AsText can write beyond an allocated output buffer when converting     deeply nested GeometryCollections because recursive WKT serialization does not account for bytes consumed     or reserve sufficient space. A low-privileged remote attacker can submit a specially crafted GIS object to     corrupt memory and potentially achieve code execution when combined with another vulnerability. This issue     is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-85746)

    A flaw was found in MariaDB. An authenticated database user with low privileges can trigger a use-after-     free memory corruption condition during cursor FETCH operations involving SYS_REFCURSOR. This flaw allows     an attacker to corrupt memory and hijack program execution flow, potentially leading to privilege     escalation and arbitrary code execution on the host system or causing a denial of service (DoS) by     crashing the database server. (CVE-2026-85748)

    MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19,     11.4.13, 11.8.9, 12.3.3, and 13.0.2, the CONNECT engine plugin file-access UDFs json_file(), bson_file(),     jfile_make(), bfile_make(), and jbin_file() are affected because each does not enforce FILE privilege or     the secure_file_priv setting. A low-privileged attacker can trigger the issue by calling a CONNECT file-     access UDF with a filesystem path, then invoke a CONNECT file-access UDF to access a filesystem path and     read or write files that the database account is not authorized to access, subject to operating-system     permissions. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.

A low-privileged     attacker can trigger the issue when an attacker-created object with crafted identifiers or values is     included in SHOW output or a dump, then create an object with crafted identifiers or values so generated     SQL contains injected statements and execute attacker-injected SQL when the poisoned output is applied.
    This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2. (CVE-2026-86047)

An attacker can trigger the issue with a     table name using the #mysql50# prefix, then use a #mysql50# table name to access files under their legacy     unencoded name and cause crashes, data corruption, data exfiltration, or remote code execution.
