File disclosure via weak transfer hotspot passphrase
Published Jun 23, 2025 · Updated Jan 6, 2026
Information disclosure in OPPO ColorOS 15.0.2 and earlier allows physically proximate attackers to read Clone Phone transfer data. Clone Phone creates a Wi-Fi hotspot protected only by a weak WPA passphrase, allowing the passphrase to be brute-forced and the transfer network accessed. The attacker must be within Wi-Fi range while a migration is active; exposure is limited to files traversing that temporary hotspot.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
