Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Apple Safari detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Apple Safari fails to properly detect HTTP content (especially scripts) loaded within HTTPS pages when the top-level frame uses HTTPS, allowing man-in-the-middle attackers to inject malicious web scripts into the context of secure HTTPS sites by modifying HTTP pages to include HTTPS iframes that reference HTTP-hosted script files.

MitigationThis is a browser-side vulnerability that was patched in older Safari versions; web applications should ensure all external resources (scripts, stylesheets, iframes) are served exclusively over HTTPS to prevent mixed content attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Safari version
    Open Safari, click Safari menu, select 'About Safari' to display the version number (e.g., 3.2.1, 1.1.0, etc.)
    Affected if The displayed version is 3.2.1 or lower, or exactly matches 0.8, 0.9, 1.0, 1.0.0, 1.0.0b1, 1.0.0b2, 1.0.1, 1.0.2, 1.0.3, 1.1, or 1.1.0
  2. Confirm version is within affected range
    Compare your installed version number against the list: versions <= 3.2.1 and the specific versions 0.8, 0.9, 1.0, 1.0.0, 1.0.0b1, 1.0.0b2, 1.0.1, 1.0.2, 1.0.3, 1.1, 1.1.0 are vulnerable
    Affected if Your Safari version appears in the affected list
  3. Verify browser is used for HTTPS browsing
    Check whether Safari is used to access HTTPS websites, particularly ones that may load external resources
    Affected if You use Safari to browse HTTPS sites and those sites load scripts, iframes, or stylesheets from HTTP sources (mixed content)

You are affected if your Safari version is 3.2.1 or lower, or exactly matches one of the listed vulnerable versions (0.8 through 1.1.0), and you use the browser to view HTTPS pages that could load HTTP-hosted resources.
