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-2026-13397 in the wild and no public exploit code.\n\nAffected product: CODECHILD HTML::Bare. 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-2026-13397/ (Markdown: https://insights.sbomify.com/CVE-2026-13397/index.md)","id":"CVE-2026-13397","markdown":"https://insights.sbomify.com/CVE-2026-13397/index.md","name":"CVE-2026-13397","record":{"aliases":["GHSA-xfxg-9rjg-hqrw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl HTML parser","requires_auth":"none","summary":"An attacker can cause a denial of service by providing malformed HTML attributes that trigger an infinite loop in the HTML::Bare Perl parser.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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":"HTML::Bare versions through 0.04 for Perl will hang in an infinite loop when parsing malformed attributes.\n\nThe parserc_parse function never advances the attribute-parse state cursor on certain malformed attribute forms, looping forever.\n\nNameless attributes such as \"\u003ca ='c'\u003e\" or unbalanced quotes \"\u003ca b='''''''c'\u003e\" can trigger this condition.\n\nNote that the latest version available on CPAN is version 0.02.
