HarmonyOS: Authentication Bypass by Primary Weakness
CVE-2025-53167 is a high-severity authentication bypass by primary weakness vulnerability in HarmonyOS from Huawei, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected HarmonyOS versions: 5.1.0; 5.0.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.23% 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
- Check which version of HarmonyOS you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on consumer.huawei.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
