A security researcher uncovered an unsecured Elasticsearch database belonging to Adobe Creative Cloud subscription service that was accessible to anyone without any password or authentication. The exposed data is severe enough to expose Adobe CC users to highly targeted and convincing phishing attacks. Adobe responded to the security incident swiftly and shut off public access to the database on the same day. It’s unknown if the database had been unauthorizedly accessed by anyone else before the researcher discovered it, but in case they did, users should be suspicious of phishing emails.
