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-2019-9942 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- twig/twig (Packagist): affected all versions; fixed in 1.38.0\n- twig/twig (Packagist): affected all versions; fixed in 1.38.0\n- twig/twig (Packagist): affected from 2.0.0; fixed in 2.7.0\n- twig/twig (Packagist): affected from 2.0.0; fixed in 2.7.0\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-2019-9942/ (Markdown: https://insights.sbomify.com/CVE-2019-9942/index.md)","id":"CVE-2019-9942","markdown":"https://insights.sbomify.com/CVE-2019-9942/index.md","name":"CVE-2019-9942","record":{"aliases":["DSA-4419-1","GHSA-vxrc-68xx-x48g","UBUNTU-CVE-2019-9942"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Twig template engine","requires_auth":"none","summary":"An attacker can bypass Twig sandbox restrictions to call __toString() on unauthorized objects, potentially disclosing sensitive information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"twig","vendor":"symfony"}],"cvss":{"score":3.7,"severity":"low","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[],"description":"A sandbox information disclosure exists in Twig before 1.38.0 and 2.x before 2.7.0 because, under some circumstances, it is possible to call the __toString() method on an object even if not allowed by the security policy in place.","ecosystems":["Packagist"],"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":"Twig Sandbox Information Disclosure","id":"CVE-2019-9942","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"information_disclosure","year":"2019"},"n_packages":4,"n_references":4,"next":{"headline":"Missing authorization in n/a","id":"CVE-2019-9943"},"packages":[{"ecosystem":"Packagist","fixed":["1.38.0"],"introduced":["0"],"last_affected":[],"package":"twig/twig","purl":null,"source":"GHSA-vxrc-68xx-x48g"},{"ecosystem":"Packagist","fixed":["1.38.0"],"introduced":["0"],"last_affected":[],"package":"twig/twig","purl":"pkg:composer/twig/twig","source":"GHSA-vxrc-68xx-x48g"},{"ecosystem":"Packagist","fixed":["2.7.0"],"introduced":["2.0.0"],"last_affected":[],"package":"twig/twig","purl":null,"source":"GHSA-vxrc-68xx-x48g"},{"ecosystem":"Packagist","fixed":["2.7.0"],"introduced":["2.0.0"],"last_affected":[],"package":"twig/twig","purl":"pkg:composer/twig/twig","source":"GHSA-vxrc-68xx-x48g"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2019-9939"},"products":["n/a"],"published":"2019-03-23","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"An attacker can bypass Twig sandbox restrictions to call __toString() on unauthorized objects, potentially disclosing sensitive information.","url":"https://insights.sbomify.com/CVE-2019-9942/"}
