The Pulsar IO Apache Kafka Source Connector, Sink Connector, and Kafka Connect Adaptor Sink Connector log sensitive configuration properties in plain text in application logs.\n\n\nThis vulnerability can lead to unintended exposure of credentials in log files, potentially allowing attackers with access to these logs to obtain Apache Kafka credentials. The vulnerability's impact is limited by the fact that an attacker would need access to the application logs to exploit this issue.\n\nThis issue affects Apache Pulsar IO's Apache Kafka connectors in all versions before 3.0.11, 3.3.6, and 4.0.4.\n\n\n3.0.x version users should upgrade to at least 3.0.11.\n\n3.3.x version users should upgrade to at least 3.3.6.\n\n4.0.x version users should upgrade to at least 4.0.4.\n\n\nUsers operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N","score":6.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-532"],"references":["https://lists.apache.org/thread/zv5fwwrh374r1p5cmksxcd40ssxxko3d","https://pulsar.apache.org/security/","http://www.openwall.com/lists/oss-security/2025/04/09/2"],"products":["apache:pulsar"],"source":"nvd","synced_at":"2026-10-19T22:00:57.946988208+00:00"},"epss":{"cve":"CVE-2025-30677","score":0.0073,"percentile":0.54286,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rcqj-3fmp-5cqx","url":"https://osv.dev/vulnerability/GHSA-rcqj-3fmp-5cqx","summary":"Apache Pulsar Kafka Connector Logs Sensitive Information in Application Logs","modified":"2025-07-15T23:35:54.161131Z","packages":[{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-io-kafka-connect-adaptor","purl":"pkg:maven/org.apache.pulsar/pulsar-io-kafka-connect-adaptor","ranges":["<3.0.11"],"fixed":["3.0.11"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-io-kafka-connect-adaptor","purl":"pkg:maven/org.apache.pulsar/pulsar-io-kafka-connect-adaptor","ranges":[">=3.3.0 <3.3.6"],"fixed":["3.3.6"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-io-kafka-connect-adaptor","purl":"pkg:maven/org.apache.pulsar/pulsar-io-kafka-connect-adaptor","ranges":[">=4.0.0 <4.0.4"],"fixed":["4.0.4"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-io-kafka","purl":"pkg:maven/org.apache.pulsar/pulsar-io-kafka","ranges":["<3.0.11"],"fixed":["3.0.11"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-io-kafka","purl":"pkg:maven/org.apache.pulsar/pulsar-io-kafka","ranges":[">=3.3.0 <3.3.6"],"fixed":["3.3.6"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-io-kafka","purl":"pkg:maven/org.apache.pulsar/pulsar-io-kafka","ranges":[">=4.0.0 <4.0.4"],"fixed":["4.0.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
