Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-34728 exists.\n\nAffected packages and fixed versions:\n- phpmyfaq/phpmyfaq (Packagist): affected all versions; fixed in 4.1.1\n- phpmyfaq/phpmyfaq (Packagist): affected all versions; fixed in 4.1.1\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-2026-34728/ (Markdown: https://insights.sbomify.com/CVE-2026-34728/index.md)","id":"CVE-2026-34728","markdown":"https://insights.sbomify.com/CVE-2026-34728/index.md","name":"CVE-2026-34728","record":{"aliases":["GHSA-38m8-xrfj-v38x"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"phpMyFAQ","requires_auth":"low_privilege","summary":"An attacker can delete arbitrary files on the server via path traversal in the media browser, potentially leading to data loss or service disruption.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"phpmyfaq","vendor":"phpmyfaq"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"phpMyFAQ is an open source FAQ web application. Prior to version 4.1.1, the MediaBrowserController::index() method handles file deletion for the media browser. When the fileRemove action is triggered, the user-supplied name parameter is concatenated with the base upload directory path without any path traversal validation. The FILTER_SANITIZE_SPECIAL_CHARS filter only encodes HTML special characters (\u0026, ', \", \u003c, \u003e) and characters with ASCII value \u003c 32, and does not prevent directory traversal sequences like ../. Additionally, the endpoint does not validate CSRF tokens, making it exploitable via CSRF attacks.
