Technical description

Hypequery is a TypeScript semantic layer for ClickHouse. Prior to 2.0.2, escapeValue() in packages/clickhouse/src/core/utils.ts did not escape backslashes before single quotes during parameter substitution, allowing attacker controlled query parameters with a trailing backslash to escape the closing quote and inject arbitrary SQL. This issue is fixed in version 2.0.2.

CVE-2026-153444.9 MED

—

———The WP Photo Album Plus plugin for WordPress is vulnerable to generic SQL Injection via the 'table' parameter in all versions up to, and including, 9.2.04.002 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The export-table endpoint lacks a nonce check, meaning this vulnerability can also be triggered via CSRF by tricking an authenticated administrator into visiting a malicious page.5h CVE-2026-6881—

———IBM Sterling B2B Integrator 6.2.0.0 through 6.2.0.5_2, 6.2.1.0 through 6.2.1.1_2, and 6.2.2.0 through 6.2.2.0_1 and IBM Sterling File Gateway 6.2.0.0 through 6.2.0.5_2, 6.2.1.0 through 6.2.1.1_2, and 6.2.2.0 through 6.2.2.0_1 is vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, which could allow the attacker to view, add, modify, or delete information in the back-end database.4h CVE-2026-50736—

———The pglogical queue mechanism, used to convey out-of-band commands such as replicated DDL from a publisher to a subscriber, executes message payloads on the subscriber at the privilege level of the apply worker, which is equivalent to a PostgreSQL superuser in default installations. A party acting as the publisher can send crafted queue messages that cause arbitrary SQL to be executed on the subscriber as superuser, escalating from a role permitted to use pglogical to full superuser and breaking the isolation between tenants in shared deployments. To exploit the issue an attacker must be able to direct a subscription at an endpoint they control. In default installations this requires privileges normally reserved for a superuser, so the issue is most relevant to managed deployments where the ability to create subscriptions has been delegated to non-superuser roles.13h CVE-2026-153046.5 MED

———The Plugin Organizer plugin for WordPress is vulnerable to SQL Injection via the 'PO_plugin_path' parameter in versions up to, and including, 10.2.4. This is due to insufficient escaping on the user-supplied parameter in the perform_plugin_search() function, where esc_sql() output is passed as the replacement string to preg_replace(), which collapses backslash escapes and defeats the quoting protection; additionally, the AJAX handler lacks both nonce verification and capability checks. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.13h
