Security readout for executives and security teams
Plain-English summary
CVE-2022-0834 is a stored cross-site scripting issue in the Amelia WordPress booking plugin. An attacker could place script content in a customer last name field, and that script may run when someone views the affected booking calendar date.
Executive priority
Prioritize remediation for public WordPress booking sites because this can expose visitors or staff to attacker-controlled browser script. Treat it as high priority where Amelia is internet-facing and outdated.
Technical view
Sources describe insufficient sanitization and escaping of the lastName parameter in Amelia’s AddCustomerController.php. The issue affects Amelia versions up to and including 1.0.46 and is mapped to CWE-79 with CVSS 3.1 score 7.2.
Likely exposure
Exposure is likely limited to WordPress sites running Amelia Booking for Appointments and Events Calendar at version 1.0.46 or earlier, especially where public booking or customer creation workflows are enabled.
Exploitation context
The source bundle does not show CISA KEV listing or other cited evidence of active exploitation. The CVSS vector indicates network reachability, low complexity, no privileges required, changed scope, and limited confidentiality and integrity impact.
Researcher notes
The narrative source states versions up to and including 1.0.46 are affected. The supplied affected-product record appears inconsistent, listing version 0 and defaultStatus unaffected, so validate against Wordfence and CVE records before final scoping.
Mitigation direction
- Inventory WordPress sites using the Amelia booking plugin.
- Identify any Amelia installations at version 1.0.46 or earlier.
- Check vendor or Wordfence guidance for the fixed release before changing production.
- Update Amelia to a vendor-supported fixed version when confirmed.
- If no fix is available, assess temporarily disabling exposed booking workflows.
Validation and detection
- Confirm the installed Amelia plugin version from WordPress administration or asset inventory.
- Review booking calendar pages for unexpected script execution or altered customer names.
- Inspect customer records for suspicious lastName values containing markup or script-like content.
- Check web and WordPress logs for unusual booking or customer creation activity.
