An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-28695 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 5.8.7; fixed in 5.9.0-beta.1\n- craftcms/cms (Packagist): affected from 5.8.7; 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-2026-28695/ (Markdown: https://insights.sbomify.com/CVE-2026-28695/index.md)","id":"CVE-2026-28695","markdown":"https://insights.sbomify.com/CVE-2026-28695/index.md","name":"CVE-2026-28695","record":{"aliases":["GHSA-94rc-cqvm-m4pw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Craft CMS","requires_auth":"high_privilege","summary":"Authenticated administrators can achieve remote code execution in Craft CMS via Server-Side Template Injection using the create() function and Symfony Process gadget.","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":7.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/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). There is an authenticated admin RCE in Craft CMS 5.8.21 via Server-Side Template Injection using the create() Twig function combined with a Symfony Process gadget chain. The create() Twig function exposes Craft::createObject(), which allows instantiation of arbitrary PHP classes with constructor arguments. Combined with the bundled symfony/process dependency, this enables RCE. This bypasses the fix implemented for CVE-2025-57811 (patched in 5.8.7).
