An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-0291 in the wild and no public exploit code.\n\nAffected product: expresstech Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-0291/ (Markdown: https://insights.sbomify.com/CVE-2023-0291/index.md)","id":"CVE-2023-0291","markdown":"https://insights.sbomify.com/CVE-2023-0291/index.md","name":"CVE-2023-0291","record":{"aliases":["GHSA-qfx5-pmrr-ggvv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can delete arbitrary media files due to a missing capability check in the Quiz And Survey Master WordPress plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"quiz_and_survey_master","vendor":"expresstech"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The Quiz And Survey Master for WordPress is vulnerable to authorization bypass due to a missing capability check on the function associated with the qsm_remove_file_fd_question AJAX action in versions up to, and including, 8.0.8.
