CVE-2026-115724
VLC for Android before 3.7.2 File Overwrite via Spoofed Mail Attachment Provider
VLC for Android before 3.7.2 contains a confused-deputy file overwrite vulnerability in FileUtils.getUri() that trusts content URIs based only on the com.fsck.k9.attachmentprovider or gmail-ls authority. A co-installed app without permissions can declare these authorities and send a crafted VIEW intent to the exported StartActivity, making VLC write attacker-chosen content under an attacker-chosen name in the shared Download directory, overwriting other apps' files when VLC holds All files access.
