Published: 11 March 2026
Summary
CVE-2026-3496 is a high-severity SQL Injection (CWE-89) vulnerability in Crocoblock (inferred from references). Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 26.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-3496 is a SQL injection vulnerability in the JetBooking plugin for WordPress, affecting all versions up to and including 4.0.3. The issue stems from insufficient escaping of the user-supplied 'check_in_date' parameter and lack of sufficient preparation in the existing SQL query, allowing attackers to append additional SQL queries.
Unauthenticated attackers can exploit this vulnerability remotely with low attack complexity and no user interaction required, as reflected in its CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Exploitation enables extraction of sensitive information from the database, mapped to CWE-89.
Mitigation details are provided in advisories at the Crocoblock changelog for the JetBooking plugin (https://crocoblock.com/changelog/?plugin=jet-booking) and Wordfence threat intelligence (https://www.wordfence.com/threat-intel/vulnerabilities/id/35e33e30-e102-445a-99d0-27adb7fc4638?source=cve).
