Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-12546 in the wild and no public exploit code.\n\nAffected product: The Eclipse Foundation Eclipse Mosquitto. 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-2018-12546/ (Markdown: https://insights.sbomify.com/CVE-2018-12546/index.md)","id":"CVE-2018-12546","markdown":"https://insights.sbomify.com/CVE-2018-12546/index.md","name":"CVE-2018-12546","record":{"aliases":["ALPINE-CVE-2018-12546","DEBIAN-CVE-2018-12546","GHSA-mx88-h56f-w25v","UBUNTU-CVE-2018-12546"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MQTT broker","requires_auth":"low_privilege","summary":"Revoked clients can still receive retained messages, allowing unauthorized data access in Eclipse Mosquitto MQTT brokers.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"mosquitto","vendor":"eclipse"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"In Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) when a client publishes a retained message to a topic, then has its access to that topic revoked, the retained message will still be published to clients that subscribe to that topic in the future.
