An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-30189 in the wild and no public exploit code.\n\nAffected product: Open-Xchange GmbH OX Dovecot Pro. 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-2025-30189/ (Markdown: https://insights.sbomify.com/CVE-2025-30189/index.md)","id":"CVE-2025-30189","markdown":"https://insights.sbomify.com/CVE-2025-30189/index.md","name":"CVE-2025-30189","record":{"aliases":["ALPINE-CVE-2025-30189","AZL-69833","AZL-69835","DEBIAN-CVE-2025-30189","DSA-6019-1","GHSA-396v-898v-98hg","SUSE-SU-2025:21159-1","UBUNTU-CVE-2025-30189","openSUSE-SU-2025:15676-1","openSUSE-SU-2025:20113-1"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Dovecot mail server","requires_auth":"none","summary":"Enabling cache causes userdb drivers to share cache keys, allowing attackers to impersonate other users after a cached login.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-1250","name":"Improper Preservation of Consistency Between Independent Representations of Shared State"}],"description":"When cache is enabled, some passdb/userdb drivers incorrectly cache all users with same cache key, causing wrong cached information to be used for these users.
