CVE-2025-13470

7.5 · HIGH
Published Nov 21, 2025 CWE-330 EPSS 0.30% (22th pctl)

Overview

CVE-2025-13470 is a high-severity vulnerability. It was published on November 21, 2025 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

In RNP version 0.18.0 a refactoring regression causes the symmetric

session key used for Public-Key Encrypted Session Key (PKESK) packets to

be left uninitialized except for zeroing, resulting in it always being

an all-zero byte array.

Any data encrypted using public-key encryption

in this release can be decrypted trivially by supplying an all-zero

session key, fully compromising confidentiality.

The vulnerability affects only public key encryption (PKESK packets).  Passphrase-based encryption (SKESK packets) is not affected.

Root cause: Vulnerable session key buffer used in PKESK packet generation.

The defect was introduced in commit `7bd9a8dc356aae756b40755be76d36205b6b161a` where initialization

logic inside `encrypted_build_skesk()` only randomized the key for the

SKESK path and omitted it for the PKESK path.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
