No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-115644/ (Markdown: https://insights.sbomify.com/CVE-2026-115644/index.md)","id":"CVE-2026-115644","markdown":"https://insights.sbomify.com/CVE-2026-115644/index.md","name":"CVE-2026-115644","record":{"aliases":["GHSA-jmxh-862m-3gxj","UBUNTU-CVE-2026-115644"],"analysis":null,"analysis_generated_by":null,"assigner":"apache","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Apache Kafka Connect contains an authentication bypass vulnerability affecting the admin REST API when admin.listeners is configured with a separate listener from the main listeners property.\n\nWhen operators isolate the admin REST API by explicitly configuring the \"admin.listeners\" property, REST extensions specified via rest.extension.classes (such as BasicAuthSecurityRestExtension) are not registered or applied to the admin resource configuration.\n\nWhile the primary REST API listener (configured via listeners) enforces configured authentication and authorization filters, endpoints mounted under the separate admin listener (/admin/loggers) fail to inherit or instantiate these extension filters. As a result, the admin logger endpoint accepts unauthenticated read and write requests even when security extensions are active on the main listener.\n\nImpact:\n\nAn unauthenticated attacker with network access to the admin listener can:\n\n  1. Read the complete set of logger names and levels, disclosing loaded class names and which security extensions are in use.\n  2. Write logger levels, including with scope=cluster which propagates the change to all workers in the Connect cluster. This can be used to suppress\n     logging (setting root to OFF) or generate excessive log output (setting root to TRACE), potentially impacting availability and observability.\n\nMitigation:\n\n  Users who cannot upgrade immediately can remove the admin.listeners configuration (or leave it unset). When unset, admin resources share the regular listener and inherit its security extensions.\n\nResolution:\n\nFrom Apache Kafka 4.2.2, 4.3.2, and 4.4.0, we make sure the REST extensions specified via \"rest.extension.classes\" will also apply to \"admin.listeners\".","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache Kafka: Connect Admin REST API Authentication Bypass via Unapplied REST Extensions","id":"CVE-2026-115644","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"KNIME Analytics Platform logs credentials of configured proxy when used as an executor","id":"CVE-2026-115657"},"packages":[],"prev":{"headline":"OpenStack Ironic through 39.0.1 allows a denial of service via a configdrive that results in a very large amount of uncompressed data, aka a gzip bomb.","id":"CVE-2026-115638"},"products":["Apache Kafka"],"published":"2026-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Apache Software Foundation"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-115644/"}
