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-2017-20285 in the wild and no public exploit code.\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-2017-20285/ (Markdown: https://insights.sbomify.com/CVE-2017-20285/index.md)","id":"CVE-2017-20285","markdown":"https://insights.sbomify.com/CVE-2017-20285/index.md","name":"CVE-2017-20285","record":{"aliases":["DEBIAN-CVE-2017-20285","GHSA-c454-fc94-q86x","UBUNTU-CVE-2017-20285"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl YAML library","requires_auth":"none","summary":"Attackers can execute arbitrary code or delete files by crafting malicious YAML documents that trigger unsafe DESTROY methods in Perl applications.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"},{"id":"CWE-470","name":"Use of Externally-Controlled Input to Select Classes or Code"}],"description":"YAML versions before 1.30 for Perl allow a loaded document to trigger the DESTROY method of arbitrary classes.\n\nA perl/hash:Class tag blesses a hash into the class it names.
