Directory traversal vulnerability in the SwiftKey language-pack update implementation on Samsung Galaxy S4, S4 Mini, S5, and S6 devices allows remote web servers to write to arbitrary files, and consequently execute arbitrary code in a privileged context, by leveraging control of the skslm.swiftkey.net domain name and providing a .. (dot dot) in an entry in a ZIP archive, as demonstrated by a traversal to the /data/dalvik-cache directory.
Conclusion & alert: CVE-2015-4641 is rated High Exploit Risk (74.5/100): CVSS Medium severity, with medium exploitation likelihood (EPSS 3.68%). Core evidence: 4 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +3.01% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
