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-2026-8594 in the wild and no public exploit code.\n\nAffected product: NEZUMI Text::LineFold. 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-2026-8594/ (Markdown: https://insights.sbomify.com/CVE-2026-8594/index.md)","id":"CVE-2026-8594","markdown":"https://insights.sbomify.com/CVE-2026-8594/index.md","name":"CVE-2026-8594","record":{"aliases":["AZL-89297","DEBIAN-CVE-2026-8594","GHSA-xfcf-wwr2-w555","MGASA-2026-0320","UBUNTU-CVE-2026-8594"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl text processing library","requires_auth":"none","summary":"Attackers can cause denial of service by triggering excessive resource consumption through duplicate output generation in the Text::LineFold Perl module.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":6.2,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-407","name":"Inefficient Algorithmic Complexity"},{"id":"CWE-405","name":"Asymmetric Resource Consumption (Amplification)"}],"description":"Text::LineFold versions through 2019.001 for Perl duplicate the output based on the number of special break characters.\n\nText::LineFold splits the input string by specific line break characters (such as VT, FF and others) into segments, but applies the break function to the entire string, not just the segment.\n\nA side effect of this is that the full input can be duplicated for each segment.
