Name of the Vulnerable Software and Affected Versions: Odyssey CMS versions up to 10.34 Description: A key management error can occur due to the manipulation of the `g-recaptcha-response` argument in an unknown function of the file /modules/odyssey contact form/odyssey contact form.php of the component reCAPTCHA Handler. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. Recommendations: For Odyssey CMS versions up to 10.34, as a temporary workaround, consider restricting access to the reCAPTCHA Handler component until a patch is available. Avoid using the `g-recaptcha-response` argument in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
