SCA: Apache Kafka Client Arbitrary File Read and Server Side Request Forgery Vulnerability (GHSA-vgq5-3255-v292)

high Tenable Self-Hosted Container Security Plugin ID 435134

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A possible arbitrary file read and SSRF vulnerability has been identified in Apache Kafka Client. Apache
 Kafka Clients accept configuration data for setting the SASL/OAUTHBEARER connection with the brokers,
 including "sasl.oauthbearer.token.endpoint.url" and "sasl.oauthbearer.jwks.endpoint.url". Apache Kafka
 allows clients to read an arbitrary file and return the content in the error log, or sending requests to
 an unintended location. In applications where Apache Kafka Clients configurations can be specified by an
 untrusted party, attackers may use the "sasl.oauthbearer.token.endpoint.url" and
 "sasl.oauthbearer.jwks.endpoint.url" configuratin to read arbitrary contents of the disk and environment
 variables or make requests to an unintended location. In particular, this flaw may be used in Apache Kafka
 Connect to escalate from REST API access to filesystem/environment/URL access, which may be undesirable in
 certain environments, including SaaS products. Since Apache Kafka 3.9.1/4.0.0, we have added a system
 property ("-Dorg.apache.kafka.sasl.oauthbearer.allowed.urls") to set the allowed urls in SASL JAAS
 configuration. In 3.9.1, it accepts all urls by default for backward compatibility. However in 4.0.0 and
 newer, the default value is empty list and users have to set the allowed urls explicitly. (CVE-2025-27817)
