Lifecycle Timeline
4DescriptionCVE.org
The Online Scheduling and Appointment Booking System WordPress plugin before 27.8 does not sanitize or properly cast a user-supplied parameter from its unauthenticated front-end booking requests before using it in a SQL query, allowing unauthenticated attackers to perform SQL injection attacks and extract sensitive data such as password hashes from the database.
AnalysisAI
SQL injection in the Online Scheduling and Appointment Booking System WordPress plugin before version 27.8 lets unauthenticated attackers extract sensitive database contents, including WordPress user password hashes, through the plugin's public-facing booking request handler. The flaw stems from a user-supplied parameter being neither sanitized nor properly type-cast before use in a SQL query, and is reachable pre-authentication over the network. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The specific prerequisite is that the site runs the Online Scheduling and Appointment Booking System plugin at a version below 27.8 with its public front-end booking functionality reachable by anonymous visitors - the injectable parameter is delivered through an unauthenticated booking request, so no account, credentials, or user interaction are needed (CVSS PR:N/UI:N, AV:N/AC:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed but lean toward genuine, prioritizable risk for exposed sites. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An anonymous attacker sends a crafted booking request to the plugin's public front-end endpoint, injecting SQL through the unsanitized parameter to run a UNION or blind query against the WordPress database. With no authentication or user interaction required and low attack complexity, they iterate to dump the wp_users table and exfiltrate administrator password hashes for offline cracking. … |
| Remediation | Vendor-released patch: upgrade the Online Scheduling and Appointment Booking System plugin to version 27.8 or later, which addresses the missing sanitization and type-casting of the booking parameter. … Detailed patch versions, workarounds, and compensating controls in full report. |
