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-2013-0277 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- activerecord (RubyGems): affected all versions; fixed in 2.3.17\n- activerecord (RubyGems): affected all versions; fixed in 2.3.17\n- activerecord (RubyGems): affected from 3.0.0; fixed in 3.1.0\n- activerecord (RubyGems): affected from 3.0.0; fixed in 3.1.0\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-2013-0277/ (Markdown: https://insights.sbomify.com/CVE-2013-0277/index.md)","id":"CVE-2013-0277","markdown":"https://insights.sbomify.com/CVE-2013-0277/index.md","name":"CVE-2013-0277","record":{"aliases":["DEBIAN-CVE-2013-0277","GHSA-fhj9-cjjh-27vm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby on Rails","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via crafted serialized YAML attributes in Ruby on Rails ActiveRecord.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"rails","vendor":"rubyonrails"},{"product":"ruby_on_rails","vendor":"rubyonrails"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[],"description":"ActiveRecord in Ruby on Rails before 2.3.17 and 3.x before 3.1.0 allows remote attackers to cause a denial of service or execute arbitrary code via crafted serialized attributes that cause the +serialize+ helper to deserialize arbitrary YAML.","ecosystems":["RubyGems"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Active Record contains deserialization of arbitrary YAML","id":"CVE-2013-0277","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"rubyonrails:rails","products":["rubyonrails:rails"],"type":"deserialization","year":"2013"},"n_packages":4,"n_references":11,"next":{"headline":"Denial of service in n/a","id":"CVE-2013-0281"},"packages":[{"ecosystem":"RubyGems","fixed":["2.3.17"],"introduced":["0"],"last_affected":[],"package":"activerecord","purl":null,"source":"GHSA-fhj9-cjjh-27vm"},{"ecosystem":"RubyGems","fixed":["2.3.17"],"introduced":["0"],"last_affected":[],"package":"activerecord","purl":"pkg:gem/activerecord","source":"GHSA-fhj9-cjjh-27vm"},{"ecosystem":"RubyGems","fixed":["3.1.0"],"introduced":["3.0.0"],"last_affected":[],"package":"activerecord","purl":null,"source":"GHSA-fhj9-cjjh-27vm"},{"ecosystem":"RubyGems","fixed":["3.1.0"],"introduced":["3.0.0"],"last_affected":[],"package":"activerecord","purl":"pkg:gem/activerecord","source":"GHSA-fhj9-cjjh-27vm"}],"prev":{"headline":"ActiveRecord vulnerable to modification of protected model attributes","id":"CVE-2013-0276"},"products":["n/a"],"published":"2013-02-13","related":[{"cvss_score":8.1,"headline":"SQL injection in n/a","id":"CVE-2017-17916","kev_date_added":null,"published":"2017-12-29"},{"cvss_score":8.1,"headline":"SQL injection in n/a","id":"CVE-2017-17917","kev_date_added":null,"published":"2017-12-29"},{"cvss_score":8,"headline":"Rails Active Storage has possible Path Traversal in DiskService","id":"CVE-2026-33195","kev_date_added":null,"published":"2026-03-23"},{"cvss_score":7.5,"headline":"Rails possible ReDoS vulnerability in Accept header parsing in Action Dispatch","id":"CVE-2024-26142","kev_date_added":null,"published":"2024-02-27"},{"cvss_score":7.5,"headline":"ReDoS based DoS vulnerability in Action Dispatch","id":"CVE-2023-22792","kev_date_added":null,"published":"2023-02-09"},{"cvss_score":7.5,"headline":"Denial of Service in Action Dispatch","id":"CVE-2021-22902","kev_date_added":null,"published":"2021-06-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or cause denial of service via crafted serialized YAML attributes in Ruby on Rails ActiveRecord.","url":"https://insights.sbomify.com/CVE-2013-0277/"}
