0 CVE-2026-93630 is a hostname canonicalization vulnerability in the email HTML sanitizers of Zimbra Collaboration Suite (ZCS). It allows an unauthenticated sender to bypass restrictions on forms targeting the Zimbra host by exploiting improper ordering of validation and canonicalization. The flaw affects ZCS versions prior to 10.1.21. Exploitation requires the recipient to open a crafted email and submit a form, potentially enabling authenticated form requests with the recipient's authentication cookie. However, it does not bypass CSRF-token protections, so state-changing attacks require additional endpoint vulnerabilities.
