Summary

CVE-2026-68566 is an unauthenticated SQL Injection (CWE-89) vulnerability affecting the BookingPress Appointment Booking Pro WordPress plugin, developed by Repute Infosystems, in versions up to and including 6.0.2. The flaw allows a remote, unauthenticated attacker to inject malicious SQL through the plugin’s booking functionality, potentially exposing sensitive database contents. The vulnerability carries a CVSS v3.1 base score of 9.3 (Critical).

Technical details

  • Root cause: improper neutralization of user-supplied input before it is used in a SQL query (CWE-89), consistent with a blind SQL injection pattern (CAPEC-7).
  • Trigger conditions: no authentication or user interaction is required to exploit the flaw.
  • Attack vector: network-based, exploitable directly against the plugin’s exposed endpoints on a WordPress site running the affected versions.
  • Impact: the CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L) indicates a scope change with high confidentiality impact and low availability impact, meaning an attacker could extract data (e.g., credentials, booking/customer records) from the underlying database and potentially affect components beyond the vulnerable module.

Affected software

  • BookingPress Appointment Booking Pro (WordPress plugin) — all versions up to and including 6.0.2.

Severity

  • CVSS v3.1 Base Score: 9.3 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L

Mitigation and recommended actions

  • Immediate: Update BookingPress Appointment Booking Pro to the latest version released by Repute Infosystems. At the time of publication, the vendor’s most recent release is 6.1 (August 20, 2026); confirm that the installed version is newer than 6.0.2 and includes a fix for this issue.
  • If immediate patching is not possible: restrict or disable public access to the plugin’s booking-related endpoints, deploy a web application firewall rule to block SQL injection patterns targeting the plugin, and monitor database logs for anomalous query activity.
  • General: Regularly audit installed WordPress plugins and apply vendor updates promptly, especially for plugins handling customer-facing forms and unauthenticated input.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
