Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16042 exists.\n\nAffected product: Unknown LWS Optimize. 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-2026-16042/ (Markdown: https://insights.sbomify.com/CVE-2026-16042/index.md)","id":"CVE-2026-16042","markdown":"https://insights.sbomify.com/CVE-2026-16042/index.md","name":"CVE-2026-16042","record":{"aliases":["GHSA-6h82-r4vw-xr2m"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated users can flush site caches without authorization, causing performance degradation and potential denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The LWS Optimize  WordPress plugin before 3.4 does not perform a capability check on its cache-clearing actions, allowing any authenticated user, including Subscribers, to flush the site's caches and force repeated cache rebuilds.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"LWS Optimize \u003c 3.4 - Subscriber+ Cache Deletion","id":"CVE-2026-16042","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Insufficient validation of guest board admin privileges on archive import","id":"CVE-2026-16044"},"packages":[],"prev":{"headline":"MStore API \u003c 4.21.0 - Unauthenticated Product Review Creation","id":"CVE-2026-16041"},"products":["LWS Optimize"],"published":"2026-08-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-04","vendors":["Unknown"]},"summary":"Authenticated users can flush site caches without authorization, causing performance degradation and potential denial of service.","url":"https://insights.sbomify.com/CVE-2026-16042/"}
