Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16066 exists.\n\nAffected product: Unknown Welcart e-Commerce. 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-2026-16066/ (Markdown: https://insights.sbomify.com/CVE-2026-16066/index.md)","id":"CVE-2026-16066","markdown":"https://insights.sbomify.com/CVE-2026-16066/index.md","name":"CVE-2026-16066","record":{"aliases":["GHSA-xgc5-xxmg-c9x4"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authors can inject scripts into product names, executing code in visitors' browsers via the Welcart e-Commerce plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Welcart e-Commerce WordPress plugin before 2.11.34 does not sanitise or escape a product field before outputting it on the product pages, allowing users with the Author role and above to inject arbitrary web scripts that execute in the browser of any visitor viewing the product page.","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":"Welcart e-Commerce \u003c 2.11.34 - Author+ Stored XSS via Product Name","id":"CVE-2026-16066","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Event Booking Manager for WooCommerce (Pro) \u003c 5.0.3 - Unauthenticated Payment Bypass via Client-Controlled Ticket Price","id":"CVE-2026-16067"},"packages":[],"prev":{"headline":"Welcart e-Commerce \u003c 2.11.32 - Editor+ SQL Injection via CSV Import","id":"CVE-2026-16065"},"products":["Welcart e-Commerce"],"published":"2026-08-12","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":"2026-08-12","vendors":["Unknown"]},"summary":"Authors can inject scripts into product names, executing code in visitors' browsers via the Welcart e-Commerce plugin.","url":"https://insights.sbomify.com/CVE-2026-16066/"}
