CVE-2026-77142

HIGHCVSS 8.8/10

Last modified

CVE-2026-77142 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. The frontend company self-service editing feature relies on a template-level visibility flag to hide the edit form for company records a visitor does not own, but the corresponding write operation does not repeat this ownership check on the server side. As a result, a visitor who knows the identifier of a company record from the public directory can submit a modified update request for that record directly and overwrite its data, without the application ever confirming that the visitor owns it..
