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-2026-4111 in the wild and no public exploit code.\n\nAffected product: Cert Manager support for Red Hat OpenShift release 1.18. 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-2026-4111/ (Markdown: https://insights.sbomify.com/CVE-2026-4111/index.md)","id":"CVE-2026-4111","markdown":"https://insights.sbomify.com/CVE-2026-4111/index.md","name":"CVE-2026-4111","record":{"aliases":["ALSA-2026:5063","ALSA-2026:5080","AZL-79886","BELL-CVE-2026-4111","CLSA-2026-1774375084","CLSA-2026-1774375835","DEBIAN-CVE-2026-4111","ECHO-bb19-1016-174f","GHSA-xrqh-48jh-pjv2","OESA-2026-1641","RHSA-2026:5063","RHSA-2026:5080","RHSA-2026:6647","RHSA-2026:7093","RHSA-2026:7105","RHSA-2026:7106","RLSA-2026:5063","RLSA-2026:5080","UBUNTU-CVE-2026-4111"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Libarchive library","requires_auth":"none","summary":"Attackers can cause persistent denial of service in applications using Libarchive by submitting crafted RAR5 archives that trigger an infinite loop during decompression.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"A flaw was identified in the RAR5 archive decompression logic of the libarchive library, specifically within the archive_read_data() processing path. When a specially crafted RAR5 archive is processed, the decompression routine may enter a state where internal logic prevents forward progress. This condition results in an infinite loop that continuously consumes CPU resources. Because the archive passes checksum validation and appears structurally valid, affected applications cannot detect the issue before processing. This can allow attackers to cause persistent denial-of-service conditions in services that automatically process archives.","ecosystems":["AlmaLinux:10","AlmaLinux:9","Red
