In MariaDB Server versions 10.6.1 to before 10.6.26, 10.11.1 to before 10.11.17, 11.4.1 to before 11.4.11, 11.8.1 to before 11.8.7, and 12.3.1 a high severity vulnerability CVE-2026-44171 was detected. This vulnerability allows an attacker to create or overwrite files outside the intended target directory. This occurs due to a path traversal flaw in the mbstream utility, which fails to check for directory traversal sequences (like /../) when unpacking an archive. While a legitimate backup never contains such paths, an attacker can provide a specially crafted archive to exploit this issue and perform arbitrary file writes. To address this issue, users should upgrade MariaDB Server to versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, or 12.3.2. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-44171.

In MongoDB versions Versions before 8.3.3, 8.2.10, 8.0.10, 7.0.35 a medium severity vulnerability CVE-2026-9748 was detected. This vulnerability allows a user to cause a mongod server crash, leading to a Denial of Service (DoS). This occurs because the $_internalConvertBucketIndexStats stage incorrectly uses PauseExecution as a mechanism to skip documents when an index stats conversion fails on non-timeseries input. However, PauseExecution is not a general-purpose skip signal; it is an internal TeeBuffer signal used solely by the $facet stage. When $_internalConvertBucketIndexStats is placed before $facet in a pipeline, the TeeBuffer receives this unexpected signal, triggers a hard invariant assertion, and crashes the server. To address this issue, users should upgrade MongoDB to a patched version 7.0.35 and later, 8.0.24 and later, 8.2.10 and later, 8.3.3 and later.

In pgAdmin 4 versions from 1.0.0 up to, but not including, 9.16.0. a medium severity vulnerability CVE-2026-12050 was detected. This vulnerability allows an authenticated user with a connected PostgreSQL session to execute arbitrary SQL statements. This occurs due to an SQL injection flaw in the named restore point endpoint (POST /browser/server/restore_point/{gid}/{sid}), where the user-supplied value field is interpolated directly into the SQL string instead of being passed as a bound parameter. While the injected SQL executes under the user’s existing database role and does not cross privilege boundaries, it bypasses application-layer restrictions, allowing SQL execution outside of the documented Query Tool interface. To address this issue, users should upgrade pgAdmin 4 to a patched version 9.16 or later. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-12050.

In MariaDB Server versions 10.6.1 to before 10.6.27, 10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, and 12.3.1 a high severity vulnerability CVE-2026-48163 was detected. This vulnerability allows a malicious joiner node to execute arbitrary shell commands on the donor node. This occurs due to improper validation of parameters sent by the joiner during a State Snapshot Transfer (SST) via the rsync method, which the donor node unsafely interpolates into the command line. To address this issue, users should upgrade MariaDB Server to versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, or 12.3.2. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-48163.

In ChromaDB Python versions 0.5.0 or later a high severity vulnerability CVE-2026-45831 was detected. This vulnerability allows an authenticated user to perform cross-tenant actions and gain unauthorized access to isolated data. This occurs because the SimpleRBACAuthorizationProvider evaluates whether a user holds a given permission, but fails to check which tenant, database, or collection that permission actually applies to. Consequently, attackers can bypass intended access restrictions across different tenant environments. There’s no fix available for this issue at the moment. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-45831.

In ChromaDB Python versions from including0.5.0 up to, including, 1.5.9 a high severity vulnerability CVE-2026-45832 was detected. This vulnerability allows an attacker to bypass authorization controls and gain unauthorized access to data. This occurs because all V1 collection-level endpoints improperly pass None for the tenant and database parameters to the authorization layer. By interacting directly with these V1 endpoints, attackers can successfully circumvent intended access restrictions. There’s no fix available for this issue at the moment. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-45832.

In MongoDB versions from including 7.0.0 and before 7.0.35, including 8.0.0 and before 8.0.24, including 8.2.0 and before 8.2.10, including 8.3.0 and before 8.3.3 a medium severity vulnerability CVE-2026-9750 was detected. This vulnerability allows an authenticated user to cause a server crash (Denial of Service) or return incorrect query results. This occurs due to insufficient separation between user-controlled document fields and internal metadata during query execution. By creating specifically crafted documents, an attacker can interfere with internal metadata processing. There’s no fix available for this issue at the moment. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-9750.

In MariaDB Server versions 10.6.1 to before 10.6.27, 10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, and 12.3.1 a high severity vulnerability CVE-2026-48165 was detected. This vulnerability allows a high-privileged MariaDB user to execute arbitrary shell commands with the privileges of the mariadbd process on the galera joiner node. This occurs due to improper handling of the wsrep_sst_receive_address or wsrep_sst_donor global system variables. To address this issue, users should upgrade MariaDB Server to versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, or 12.3.2. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-48165.

In SQLite versions before 3.53.2 a high severity vulnerability CVE-2026-11824 was detected. This vulnerability allows an attacker to cause a Denial of Service (crash) or potentially execute arbitrary code. This occurs due to a heap-based buffer overflow in the FTS5 full-text search extension (specifically within the fts5ChunkIterate() function). By supplying a specially crafted database with malicious continuation page metadata (where the szLeaf value is smaller than 4), an attacker can trigger an integer underflow. This results in an inflated remaining byte count during FTS5 MATCH query processing, leading to the overflow of attacker-controlled data into the heap. This vulnerability affects applications compiled with the SQLITE_ENABLE_FTS5 flag. To address this issue, users should upgrade SQLite to version 3.53.2.
