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-2026-16063 exists.\n\nAffected product: Unknown Event Booking Manager for WooCommerce. 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-2026-16063/ (Markdown: https://insights.sbomify.com/CVE-2026-16063/index.md)","id":"CVE-2026-16063","markdown":"https://insights.sbomify.com/CVE-2026-16063/index.md","name":"CVE-2026-16063","record":{"aliases":["GHSA-c58x-hvfg-9vjh"],"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":"Authors can inject JavaScript into event timelines, executing code in visitors' browsers, including administrators, via the Event Booking Manager 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 Event Booking Manager for WooCommerce  WordPress plugin before 5.3.7 does not sanitise or escape event timeline content submitted by users with post-editing access before storing it and rendering it on the public event page, allowing users with the Author role and above to inject arbitrary JavaScript that executes in the browser of any visitor viewing the event, including administrators.","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":"Event Booking Manager for WooCommerce \u003c 5.3.7 - Author+ Stored XSS via Event Timeline Content","id":"CVE-2026-16063","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 \u003c 5.3.7 - Contributor+ Arbitrary Post Modification via mpwem_quick_edit_event","id":"CVE-2026-16064"},"packages":[],"prev":{"headline":"Event Booking Manager for WooCommerce \u003c 5.3.7 - Contributor+ PHP Object Injection via Event Timeline and FAQ Content","id":"CVE-2026-16062"},"products":["Event Booking Manager for WooCommerce"],"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":"2026-08-03","vendors":["Unknown"]},"summary":"Authors can inject JavaScript into event timelines, executing code in visitors' browsers, including administrators, via the Event Booking Manager plugin.","url":"https://insights.sbomify.com/CVE-2026-16063/"}
