It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-64614 in the wild and no public exploit code.\n\nAffected product: EGOR Data::Deque::Shared. 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-2026-64614/ (Markdown: https://insights.sbomify.com/CVE-2026-64614/index.md)","id":"CVE-2026-64614","markdown":"https://insights.sbomify.com/CVE-2026-64614/index.md","name":"CVE-2026-64614","record":{"aliases":["GHSA-j7qm-25rr-qxjr"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl shared deque library","requires_auth":"low_privilege","summary":"Local attackers can read sensitive IPC data or hijack shared memory segments due to insecure file permissions and missing symlink protections in the Perl library.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":3.8,"severity":"low","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Data::Deque::Shared versions before 0.06 for Perl create a world-readable mmap backing file and open it without O_EXCL or O_NOFOLLOW.\n\nThe segment is created in deque.h with open(path, O_RDWR|O_CREAT, 0666).
