CVE-2021-24426

Name of the Vulnerable Software and Affected Versions The Backup by 10Web – Backup and Restore Plugin WordPress plugin versions 1.0.20 and earlier

Description The issue is related to a reflected Cross-Site Scripting problem. It occurs because the tab parameter is not properly sanitised or escaped before being outputted back in the page. This allows for malicious scripts to be injected into the webpage.

Recommendations For versions 1.0.20 and earlier, as a temporary workaround, consider restricting access to the tab parameter in the affected API endpoint until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
