An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54177 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- backpack/crud (Packagist): affected from 6.0.0; fixed in 6.8.14\n- backpack/crud (Packagist): affected from 6.0.0; fixed in 6.8.14\n- backpack/crud (Packagist): affected from 7.0.0; fixed in 7.0.38\n- backpack/crud (Packagist): affected from 7.0.0; fixed in 7.0.38\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-2026-54177/ (Markdown: https://insights.sbomify.com/CVE-2026-54177/index.md)","id":"CVE-2026-54177","markdown":"https://insights.sbomify.com/CVE-2026-54177/index.md","name":"CVE-2026-54177","record":{"aliases":["GHSA-8q2w-pv9p-mjvc"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Laravel CRUD library","requires_auth":"high_privilege","summary":"An authenticated administrator can achieve remote code execution by uploading executable files if application-level validation is missing and public disk access is enabled.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"backpack/crud provides Create, Read, Update \u0026 Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.14 and 7.0.38, HasUploadFields methods uploadFileToDisk and uploadMultipleFilesToDisk, used through CrudTrait, and the withFiles() path through FileNameGenerator do not internally reject server-executable file types. An authenticated administrator can achieve remote code execution by using an upload-enabled CRUD field without mimes: and mimetypes: validation when the public disk is web-accessible through php artisan storage:link and the web-server and PHP-FPM configuration executes the stored extension. The legacy path preserves an accepted extension and the newer path derives an extension without blocking dangerous types. The package-level restriction is defense in depth and does not replace application-level upload validation.
