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-2026-57077 in the wild and no public exploit code.\n\nAffected product: TODDR YAML::Syck. 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-2026-57077/ (Markdown: https://insights.sbomify.com/CVE-2026-57077/index.md)","id":"CVE-2026-57077","markdown":"https://insights.sbomify.com/CVE-2026-57077/index.md","name":"CVE-2026-57077","record":{"aliases":["ALPINE-CVE-2026-57077","AZL-109505","AZL-92907","BELL-CVE-2026-57077","DEBIAN-CVE-2026-57077","GHSA-5wqv-8x52-77q2","UBUNTU-CVE-2026-57077"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl YAML library","requires_auth":"none","summary":"An out-of-bounds read in YAML::Syck allows attackers to cause denial of service or disclose memory contents by parsing malicious YAML documents.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"YAML::Syck versions before 1.47 for Perl allow an out-of-bounds read via an unbounded newline scan in newline_len.\n\nIn the bundled libsyck newline_len and is_newline dereference the scan pointer, and the following byte for a \"\\r\\n\" pair, with no NUL-terminator or bounds check.
