MediumCVE-2026-13767expresstech · quiz and survey master (qsm) – quiz maker & survey maker +1 moreQuiz and Survey Master (QSM) <= 11.2.0 - Authenticated (Custom+) SQL Injection via 'pages' ParameterThe Quiz Master Next plugin for WordPress is vulnerable to SQL Injection via stored quiz page data in versions up to, and including, 11.2.0. This is due to insufficient escaping on the user-supplied 'pages' parameter persisted by the qsm_ajax_save_pages() AJAX handler (sanitize_text_field only) and lack of sufficient preparation on the existing SQL query built in qsm_options_questions_tab_content() at line 143, where the stored page IDs are interpolated into an IN() clause via implode() with no $wpdb->prepare() and no integer casting. This makes it possible for authenticated attackers, with Author-level access and above (who can own a quiz they are entitled to edit), to plant a SQL payload that is executed second-order whenever any user (including an administrator) views the quiz's Questions tab, allowing them to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.EPSS0.41%MediumCVE-2026-11780expresstech · quiz and survey master (qsm) – quiz maker & survey maker +1 moreQuiz and Survey Master (QSM) <= 11.2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'question_title' ParameterThe Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'question_title' parameter in all versions up to, and including, 11.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.EPSS0.42%MediumCVE-2026-15963expresstech · quiz and survey master (qsm) – quiz maker & survey maker +1 moreQuiz and Survey Master (QSM) <= 11.2.1 - Authenticated (Contributor+) SQL Injection via 'randon_category' Quiz OptionThe Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to generic SQL Injection via 'randon_category' Quiz Option in all versions up to, and including, 11.2.1 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 custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.EPSS0.45%HighCVE-2026-96558expresstech · quiz and survey master (qsm) – quiz maker & survey maker +1 moreQuiz and Survey Master (QSM) <= 11.2.6 - Unauthenticated Stored DOM-Based Cross-Site Scripting via 'qsm_hidden_questions' ParameterThe Quiz and Survey Master (QSM) – Quiz Maker & Survey Maker plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'qsm_hidden_questions' parameter in all versions up to, and including, 11.2.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the attacker to force the mlw_results INSERT to fail by submitting an over-length or duplicate qsm_unique_key value, which triggers the audit trail code branch that writes the unescaped payload to wp_mlw_qm_audit_trail.form_data.EPSS0.24%
