CVE-2022-23974 is a high-severity uncontrolled recursion vulnerability in Apache Pinot 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. Affected Apache Pinot versions: Apache Pinot through 0.9.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 2.08% chance of exploitation within 30 days, higher than 82% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Pinot to 0.10.0 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.

Official description
In 0.9.3 or older versions of Apache Pinot segment upload path allowed segment directories to be imported into pinot tables. In pinot installations that allow open access to the controller a specially crafted request can potentially be exploited to cause disruption in pinot service. Pinot release 0.10.0 fixes this. See https://docs.pinot.apache.org/basics/releases/0.10.0

The underlying weakness: Uncontrolled Recursion
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
How developers prevent this class of flaw
- Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
