It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-15588 exists.\n\nAffected product: Cert Manager support for Red Hat OpenShift release 1.17. 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-2026-15588/ (Markdown: https://insights.sbomify.com/CVE-2026-15588/index.md)","id":"CVE-2026-15588","markdown":"https://insights.sbomify.com/CVE-2026-15588/index.md","name":"CVE-2026-15588","record":{"aliases":["AZL-92994","BELL-CVE-2026-15588","CLSA-2026-1787154316","CLSA-2026-1788000309","CLSA-2026-1792167748","CLSA-2026-1792168154","CLSA-2026-1792168400","DEBIAN-CVE-2026-15588","ECHO-2015-e9ba-ec13","GHSA-hrq7-vgh7-p534","OESA-2026-3241","OESA-2026-3242","OESA-2026-3243","RHSA-2026:39985","RHSA-2026:40485","RHSA-2026:42329","ROOT-OS-DEBIAN-12-CVE-2026-15588","SUSE-SU-2026:23880-1","SUSE-SU-2026:23928-1","SUSE-SU-2026:23971-1","SUSE-SU-2026:23980-1","SUSE-SU-2026:4348-1","SUSE-SU-2026:4367-1","SUSE-SU-2026:4710-1","UBUNTU-CVE-2026-15588","openSUSE-SU-2026:11415-1","openSUSE-SU-2026:21977-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GLib GDBus component","requires_auth":"low_privilege","summary":"An unauthenticated attacker can cause a denial of service in applications using GLib's GDBus by sending excessively long data streams, leading to resource exhaustion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib.
