An attacker can exploit it over the internet without logging in, 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-2023-4620 exists.\n\nAffected product: Unknown Booking Calendar. 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-2023-4620/ (Markdown: https://insights.sbomify.com/CVE-2023-4620/index.md)","id":"CVE-2023-4620","markdown":"https://insights.sbomify.com/CVE-2023-4620/index.md","name":"CVE-2023-4620","record":{"aliases":["GHSA-j6vq-hjmf-4p85"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts via booking data, potentially compromising administrator accounts in the Booking Calendar plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"booking_calendar","vendor":"wpbookingcalendar"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The Booking Calendar WordPress plugin before 9.7.3.1 does not sanitize and escape some of its booking from data, allowing unauthenticated users to perform Stored Cross-Site Scripting attacks against 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":"Booking Calendar \u003c 9.7.3.1 - Unauthenticated Stored XSS","id":"CVE-2023-4620","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Use-after-free in Linux kernel's af_unix component","id":"CVE-2023-4622"},"packages":[],"prev":{"headline":"Gaining remote control over Govee devices","id":"CVE-2023-4617"},"products":["Booking Calendar"],"published":"2023-10-16","related":[{"cvss_score":9.8,"headline":"Booking Calendar \u003c= 9.9 - Unauthenticated SQL Injection","id":"CVE-2024-1207","kev_date_added":null,"published":"2024-02-08"},{"cvss_score":6.5,"headline":"WordPress Booking Calendar Plugin \u003c 9.7.4 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-51520","kev_date_added":null,"published":"2024-02-01"},{"cvss_score":6.4,"headline":"WP Booking Calendar \u003c= 10.2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via bookingform Shortcode","id":"CVE-2024-6930","kev_date_added":null,"published":"2024-07-24"},{"cvss_score":5.4,"headline":"WordPress Booking Calendar plugin \u003c= 9.2.1 - Cross-Site Request Forgery (CSRF) vulnerabiulity","id":"CVE-2022-33177","kev_date_added":null,"published":"2022-09-06"},{"cvss_score":5.3,"headline":"WP Booking Calendar \u003c= 10.10 - Unauthenticated Post-Confirmation Booking Manipulation","id":"CVE-2024-13821","kev_date_added":null,"published":"2025-02-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-02","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious scripts via booking data, potentially compromising administrator accounts in the Booking Calendar plugin.","url":"https://insights.sbomify.com/CVE-2023-4620/"}
