Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-84934 in the wild and no public exploit code.\n\nAffected product: Unknown JCH 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-2026-84934/ (Markdown: https://insights.sbomify.com/CVE-2026-84934/index.md)","id":"CVE-2026-84934","markdown":"https://insights.sbomify.com/CVE-2026-84934/index.md","name":"CVE-2026-84934","record":{"aliases":["GHSA-gpfv-rv3h-8jx7"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated users can inject scripts via AJAX actions, leading to stored XSS that executes in admin browsers, potentially enabling account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The JCH Optimize WordPress plugin before 6.0.1 does not perform a capability check on one of its authenticated AJAX actions and lets the request choose which internal action runs, allowing any authenticated users such as Subscribers to import arbitrary JCH Optimize WordPress plugin before 6.0.1 settings and store a script that executes in the browser of any visitor or administrator viewing the site.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"JCH Optimize \u003c 6.0.1 - Subscriber+ Stored XSS via getcacheinfo Task Override","id":"CVE-2026-84934","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HT Menu \u003c 1.2.7 - Subscriber+ Stored XSS via Menu Settings","id":"CVE-2026-84935"},"packages":[],"prev":{"headline":"undici vulnerable to cross-user cookie disclosure via Set-Cookie caching in shared caches","id":"CVE-2026-84933"},"products":["JCH Optimize"],"published":"2026-09-05","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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-06","vendors":["Unknown"]},"summary":"Authenticated users can inject scripts via AJAX actions, leading to stored XSS that executes in admin browsers, potentially enabling account takeover.","url":"https://insights.sbomify.com/CVE-2026-84934/"}
