Opera, probably before 7.50, sends Referer headers containing https:// URLs in requests for http:// URLs, which allows remote attackers to obtain potentially sensitive information by reading Referer log data.

Security readout for executives and security teams

This issue concerns legacy Opera behavior where a secure-page URL could be sent as a Referer when the user navigated to an insecure HTTP page. If the secure URL contained sensitive data, that data could appear in the receiving site’s logs. Exposure is most plausible where legacy Opera versions are still used and secure application URLs contain tokens, identifiers, or other sensitive values. The source bundle does not provide precise affected versions or CPEs. Low for most organizations because this is a legacy browser information leak with no cited active exploitation. Prioritize only if old Opera clients remain in operational use or sensitive data appears in URLs. Mitigation focus: Check Opera/vendor guidance for historical fixed versions and upgrade guidance.; Retire or block unsupported legacy Opera builds in managed environments.; Avoid placing secrets, tokens, or sensitive identifiers in URLs..
