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-2021-26119 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- smarty/smarty (Packagist): affected all versions; fixed in 3.1.39\n- smarty/smarty (Packagist): affected all versions; fixed in 3.1.39\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-2021-26119/ (Markdown: https://insights.sbomify.com/CVE-2021-26119/index.md)","id":"CVE-2021-26119","markdown":"https://insights.sbomify.com/CVE-2021-26119/index.md","name":"CVE-2021-26119","record":{"aliases":["DEBIAN-CVE-2021-26119","GHSA-w5hr-jm4j-9jvq","UBUNTU-CVE-2021-26119"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Smarty PHP template engine","requires_auth":"none","summary":"Attackers can execute arbitrary code by escaping the sandbox via template object access in Smarty template engine.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"smarty","vendor":"smarty"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"Smarty before 3.1.39 allows a Sandbox Escape because $smarty.template_object can be accessed in sandbox mode.","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":"Sandbox escape through template_object in smarty","id":"CVE-2021-26119","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"code_injection","year":"2021"},"n_packages":2,"n_references":5,"next":{"headline":"PHP Code Injection by malicious function name in smarty","id":"CVE-2021-26120"},"packages":[{"ecosystem":"Packagist","fixed":["3.1.39"],"introduced":["0"],"last_affected":[],"package":"smarty/smarty","purl":null,"source":"GHSA-w5hr-jm4j-9jvq"},{"ecosystem":"Packagist","fixed":["3.1.39"],"introduced":["0"],"last_affected":[],"package":"smarty/smarty","purl":"pkg:composer/smarty/smarty","source":"GHSA-w5hr-jm4j-9jvq"}],"prev":{"headline":"Flaw in ActiveMQ Artemis OpenWire support","id":"CVE-2021-26118"},"products":["n/a"],"published":"2021-02-22","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":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by escaping the sandbox via template object access in Smarty template engine.","url":"https://insights.sbomify.com/CVE-2021-26119/"}
