Apache ShenYu (incubating): Insufficiently Protected Credentials
CVE-2022-23223 is a high-severity insufficiently protected credentials vulnerability in Apache ShenYu (incubating) from Apache, 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. The record lists version 2.4.2 as the first without the flaw, so updating Apache ShenYu (incubating) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 4.31% chance of exploitation within 30 days, which is in the top 8.7% of all scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Apache ShenYu (incubating) to 2.4.2 or a later version.
- Read the advisory on lists.apache.org 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.

The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
