Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54178 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- backpack/crud (Packagist): affected from 5.0.0; no fix listed\n- backpack/crud (Packagist): affected from 5.0.0; no fix listed\n- backpack/crud (Packagist): affected from 6.0.0; fixed in 6.8.12\n- backpack/crud (Packagist): affected from 6.0.0; fixed in 6.8.12\n- backpack/crud (Packagist): affected from 7.0.0; fixed in 7.0.35\n- backpack/crud (Packagist): affected from 7.0.0; fixed in 7.0.35\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-2026-54178/ (Markdown: https://insights.sbomify.com/CVE-2026-54178/index.md)","id":"CVE-2026-54178","markdown":"https://insights.sbomify.com/CVE-2026-54178/index.md","name":"CVE-2026-54178","record":{"aliases":["GHSA-8xjm-wqrp-2f25"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Laravel CRUD library","requires_auth":"low_privilege","summary":"Authenticated users can delete arbitrary files on the server by manipulating upload field parameters, affecting Laravel Backpack CRUD users.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"},{"id":"CWE-285","name":"Improper Authorization"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"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. Prior to 6.8.12 and 7.0.35, HasUploadFields::uploadMultipleFilesToDisk in src/app/Models/Traits/HasUploadFields.php trusts disk-relative paths from clear_\u003cattribute\u003e[] and passes them to Storage::disk()-\u003edelete without confirming that the paths are persisted on the current model record. An authenticated user with Update access to a CRUD using this mutator through src/app/Models/Traits/CrudTrait.php can delete another record's attachment, a shared asset, or another operational file on the configured disk by submitting its path. The newer MultipleFiles uploader is not affected because it intersects requested deletions with the record's persisted file list. This flaw does not permit reading the deleted files. The 5.x line remains affected through its final releases.
