+Subject: org-latex-preview: Add protection when `untrusted-content' is non-nil
+
+* lisp/org/org.el (org--latex-preview-when-risky): New variable
+controlling how to handle LaTeX previews in Org files from untrusted
+origin.
+(org-latex-preview): Consult `org--latex-preview-when-risky' before
+generating previews.
+
+This patch adds a layer of protection when LaTeX preview is requested
+for an email attachment, where `untrusted-content' is set to non-nil.
