The vulnerability allowed arbitrary code execution via a malicious hyperlink in a spreadsheet document. CVE-2024-7263 was subsequently discovered during the analysis of the patch for the first vulnerability. Both flaws affected the plugin component promecefpluginhost.exe and could be triggered by a single click. The vulnerabilities impacted WPS Office versions from 12.2.0.13110 to 12.2.0.17119.
