iOS and iPadOS: Channel Accessible by Non-Endpoint
CVE-2025-31214 is a high-severity channel accessible by non-endpoint vulnerability in iOS and iPadOS from Apple, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 18.5 as the first without the flaw, so updating iOS and iPadOS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.55% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update iOS and iPadOS to 18.5 or a later version.
- Update iPadOS to 18.5 or a later version.
- Update Iphone OS to 18.5 or a later version.
- Read the advisory on support.apple.com for workarounds and exact fixed builds.

The underlying weakness: Channel Accessible by Non-Endpoint
The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint.
How developers prevent this class of flaw
- In order to establish secure communication between two parties, it is often important to adequately verify the identity of entities at each end of the communication channel. Always fully authenticate both ends of any communications channel.
- Adhere to the principle of complete mediation.
- A certificate binds an identity to a cryptographic key to authenticate a communicating party. Often, the certificate takes the encrypted form of the hash of the identity of the subject, the public key, and information such as time of issue or expiration using the issuer's private key. The certificate can be validated by deciphering the certificate with the issuer's public key. See also X.509 certificate signature chains and the PGP certification structure.
