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-2021-4339 in the wild and no public exploit code.\n\nAffected product: stylemix Directory Listings WordPress plugin – uListing. 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-2021-4339/ (Markdown: https://insights.sbomify.com/CVE-2021-4339/index.md)","id":"CVE-2021-4339","markdown":"https://insights.sbomify.com/CVE-2021-4339/index.md","name":"CVE-2021-4339","record":{"aliases":["GHSA-99h6-wmg5-777v"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can retrieve all user emails via a missing capability check in the uListing WordPress plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"ulisting","vendor":"stylemixthemes"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The uListing plugin for WordPress is vulnerable to authorization bypass due to a missing capability check in the \"ulisting/includes/route.php\" file on the /1/api/ulisting-user/search REST-API route in versions up to, and including, 1.6.6.
