CVE-2016-20069: WordPress Booking Calendar Contact Form 1.0.23 SQL Injection
WordPress Booking Calendar Contact Form 1.0.23 contains an unauthenticated blind SQL injection vulnerability in the shortcode function that fails to sanitize the calendar parameter before using it in database queries. Attackers can inject SQL commands through the calendar shortcode parameter to execute arbitrary SQL queries and extract sensitive database information.
Security readout for executives and security teams
This is a high-risk issue in a WordPress booking form plugin. A public visitor may be able to make the site’s database answer unintended queries through an unsanitized calendar parameter. The main business risk is exposure of sensitive WordPress database data on sites still running the affected plugin version. Exposure is likely limited to WordPress sites with dwbooster Booking Calendar Contact Form 1.0.23 installed and reachable, especially pages rendering the affected shortcode or booking form. Prioritize externally reachable WordPress sites using this plugin. Treat confirmed exposure as urgent because exploitation requires no login and could expose sensitive database information. Mitigation focus: Inventory WordPress sites for the affected plugin and version.; Disable or remove the plugin until vendor guidance is confirmed.; Check the vendor and VulnCheck advisory for any supported fixed release..

CWE-89: Database access and collection lookup
Injection into data stores can inform collection, data access, and exfiltration detection reviews. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references database injection or access, so collection and exfiltration review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
