This is due to insufficient sanitization of user-supplied input before being used in a SQL query. The sanitize_text_field() function applied to the merged_question parameter does not prevent SQL metacharacters like ), OR, AND, and # from being included in the value, which is then directly concatenated into a SQL IN() clause without using $wpdb->prepare() or casting values to integers. This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database."}],"title":"Quiz and Survey Master (QSM) <= 10.3.5 - Authenticated (Contributor+) SQL Injection via 'merged_question' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b32bf1cb-3722-41fc-be51-dabe80416b14?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/quiz-master-next/tags/10.3.5/php/classes/class-qsm-questions.php#L387"},{"url":"https://plugins.trac.wordpress.org/browser/quiz-master-next/tags/10.3.5/php/rest-api.php#L760"},{"url":"https://plugins.trac.wordpress.org/changeset/3486710/quiz-master-next/trunk/php/rest-api.php"},{"url":"https://plugins.trac.wordpress.org/changeset/3486710/quiz-master-next/trunk/php/classes/class-qsm-questions.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')","cweId":"CWE-89","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Thanh Hao"}],"timeline":[{"time":"2026-03-23T10:09:13.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-24T18:44:37.199895Z","id":"CVE-2026-2412","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-24T18:44:44.723Z"}}]}}
