CVE-2026-66843: CWE-829 Inclusion of Functionality from Untrusted Control Sphere in rrrene html_sanitize_exCVE-2026-66843 0 CVE-2026-66843 is a low-severity vulnerability in the html_sanitize_ex library (versions 0.3.1 up to but not including 1.5.3). It involves the inclusion of functionality from an untrusted control sphere via the data attribute of an <object> element in sanitized HTML. This allows a remote attacker to load arbitrary documents into a trusted page. However, this does not result in unconditional cross-site scripting due to browser restrictions on javascript: URLs in <object data> and the opaque origin of data: documents.
