Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-73209 in the wild and no public exploit code.\n\nAffected product: Open-Xchange GmbH OX Dovecot CE. 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-2026-73209/ (Markdown: https://insights.sbomify.com/CVE-2026-73209/index.md)","id":"CVE-2026-73209","markdown":"https://insights.sbomify.com/CVE-2026-73209/index.md","name":"CVE-2026-73209","record":{"aliases":["ALPINE-CVE-2026-73209","AZL-98283","DEBIAN-CVE-2026-73209","GHSA-r5w4-jgmp-fp92","UBUNTU-CVE-2026-73209"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IMAP server","requires_auth":"low_privilege","summary":"Authenticated attackers can crash the IMAP service by sending crafted compressed data, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"An attacker that has valid credentials can send crafted compressed data that causes the affected process to exhaust its stack and crash.
