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-2026-66639 in the wild and no public exploit code.\n\nAffected product: WPZOOM Forms – Contact Form Plugin for Gutenberg. 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-2026-66639/ (Markdown: https://insights.sbomify.com/CVE-2026-66639/index.md)","id":"CVE-2026-66639","markdown":"https://insights.sbomify.com/CVE-2026-66639/index.md","name":"CVE-2026-66639","record":{"aliases":["GHSA-h6x2-x854-wf57"],"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":"A contributor can inject malicious scripts into WPZOOM Forms, potentially leading to code execution or account takeover for other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Contributor Cross Site Scripting (XSS) in WPZOOM Forms – Contact Form Plugin for Gutenberg \u003c= 2.0.4 versions.","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":"WordPress WPZOOM Forms – Contact Form plugin for Gutenberg plugin \u003c= 2.0.4 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-66639","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Login With Ajax plugin \u003c= 4.5.1 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-66640"},"packages":[],"prev":{"headline":"WordPress Frontend Admin by DynamiApps plugin \u003c= 3.29.10 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2026-66638"},"products":["WPZOOM Forms – Contact Form Plugin for Gutenberg"],"published":"2026-08-18","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":"partial"},"state":"PUBLISHED","updated":"2026-08-18","vendors":["WPZOOM"]},"summary":"A contributor can inject malicious scripts into WPZOOM Forms, potentially leading to code execution or account takeover for other users.","url":"https://insights.sbomify.com/CVE-2026-66639/"}
