An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-28784 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- craftcms/cms (Packagist): affected from 4.0.0-RC1; fixed in 4.17.0-beta.1\n- craftcms/cms (Packagist): affected from 4.0.0-RC1; fixed in 4.17.0-beta.1\n- craftcms/cms (Packagist): affected from 5.0.0-RC1; fixed in 5.9.0-beta.1\n- craftcms/cms (Packagist): affected from 5.0.0-RC1; fixed in 5.9.0-beta.1\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-2026-28784/ (Markdown: https://insights.sbomify.com/CVE-2026-28784/index.md)","id":"CVE-2026-28784","markdown":"https://insights.sbomify.com/CVE-2026-28784/index.md","name":"CVE-2026-28784","record":{"aliases":["GHSA-qc86-q28f-ggww"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Craft CMS","requires_auth":"high_privilege","summary":"Authenticated attackers can achieve remote code execution via Twig SSTI in Craft CMS if admin changes are allowed or specific utilities are accessible.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"craft_cms","vendor":"craftcms"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1336","name":"Improper Neutralization of Special Elements Used in a Template Engine"}],"description":"Craft is a content management system (CMS). Prior to 5.8.22 and 4.16.18, it is possible to craft a malicious payload using the Twig map filter in text fields that accept Twig input under Settings in the Craft control panel or using the System Messages utility, which could lead to a RCE. For this to work, you must have administrator access to the Craft Control Panel, and allowAdminChanges must be enabled for this to work, which is against our recommendations for any non-dev environment. Alternatively, you can have a non-administrator account with allowAdminChanges disabled, but you have access to the System Messages utility. Users should update to the patched versions (5.8.22 and 4.16.18) to mitigate the issue.","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":"Craft is affected by potential authenticated Remote Code Execution via Twig SSTI","id":"CVE-2026-28784","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"craftcms:craft_cms","products":["craftcms:craft_cms"],"type":"code_injection","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Ghostfolio: Time-Based Blind SQL Injection in Manual Asset Import","id":"CVE-2026-28785"},"packages":[{"ecosystem":"Packagist","fixed":["4.17.0-beta.1"],"introduced":["4.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":null,"source":"GHSA-qc86-q28f-ggww"},{"ecosystem":"Packagist","fixed":["4.17.0-beta.1"],"introduced":["4.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":"pkg:composer/craftcms/cms","source":"GHSA-qc86-q28f-ggww"},{"ecosystem":"Packagist","fixed":["5.9.0-beta.1"],"introduced":["5.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":null,"source":"GHSA-qc86-q28f-ggww"},{"ecosystem":"Packagist","fixed":["5.9.0-beta.1"],"introduced":["5.0.0-RC1"],"last_affected":[],"package":"craftcms/cms","purl":"pkg:composer/craftcms/cms","source":"GHSA-qc86-q28f-ggww"}],"prev":{"headline":"Craft has a Twig Function Blocklist Bypass","id":"CVE-2026-28783"},"products":["cms"],"published":"2026-03-04","related":[{"cvss_score":10,"headline":"Craft CMS Code Injection","id":"CVE-2025-32432","kev_date_added":"2026-03-20","published":"2025-04-25"},{"cvss_score":9.3,"headline":"Craft CMS Code Injection","id":"CVE-2024-56145","kev_date_added":"2025-06-02","published":"2024-12-18"},{"cvss_score":8.1,"headline":"Craft CMS Code Injection","id":"CVE-2025-23209","kev_date_added":"2025-02-20","published":"2025-01-18"},{"cvss_score":6.9,"headline":"Craft CMS External Control of Assumed-Immutable Web Parameter","id":"CVE-2025-35939","kev_date_added":"2025-06-02","published":"2025-05-07"},{"cvss_score":10,"headline":"Craft CMS Remote Code Execution vulnerability","id":"CVE-2023-41892","kev_date_added":null,"published":"2023-09-13"},{"cvss_score":9.8,"headline":"Craft CMS Remote Code Injection","id":"CVE-2021-27903","kev_date_added":null,"published":"2021-06-30"},{"cvss_score":9.8,"headline":"SEOmatic for CraftCMS allows Server-Side Template Injection","id":"CVE-2020-9757","kev_date_added":null,"published":"2020-03-04"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-06","vendors":["craftcms"]},"summary":"Authenticated attackers can achieve remote code execution via Twig SSTI in Craft CMS if admin changes are allowed or specific utilities are accessible.","url":"https://insights.sbomify.com/CVE-2026-28784/"}
