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-2023-0733 exists.\n\nAffected product: Unknown Newsletter Popup. 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-2023-0733/ (Markdown: https://insights.sbomify.com/CVE-2023-0733/index.md)","id":"CVE-2023-0733","markdown":"https://insights.sbomify.com/CVE-2023-0733/index.md","name":"CVE-2023-0733","record":{"aliases":["GHSA-xc2c-p2fc-pq4v"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts via unsanitized settings in the Newsletter Popup WordPress plugin, leading to stored XSS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"newsletter_popup","vendor":"newsletter_popup_project"}],"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 Newsletter Popup WordPress plugin through 1.2 does not sanitise and escape some of its settings, which could allow unauthenticated users to perform Stored Cross-Site Scripting attacks","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":"Newsletter Popup \u003c= 1.2 - Unauthenticated Stored XSS","id":"CVE-2023-0733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Improper Authorization in wallabag/wallabag","id":"CVE-2023-0734"},"packages":[],"prev":{"headline":"SourceCodester Online Eyewear Shop POST Request Users.php registration cross site scripting","id":"CVE-2023-0732"},"products":["Newsletter Popup"],"published":"2023-05-30","related":[{"cvss_score":8.8,"headline":"Newsletter Popup \u003c= 1.2 - Record Deletion via CSRF","id":"CVE-2023-0766","kev_date_added":null,"published":"2023-05-30"}],"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":"2025-01-10","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious scripts via unsanitized settings in the Newsletter Popup WordPress plugin, leading to stored XSS.","url":"https://insights.sbomify.com/CVE-2023-0733/"}
