An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66921 exists.\n\nAffected product: n/a. 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-2025-66921/ (Markdown: https://insights.sbomify.com/CVE-2025-66921/index.md)","id":"CVE-2025-66921","markdown":"https://insights.sbomify.com/CVE-2025-66921/index.md","name":"CVE-2025-66921","record":{"aliases":["GHSA-56hc-g777-9p48"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Point of Sale system","requires_auth":"high_privilege","summary":"Remote attackers can inject arbitrary web script or HTML via the name parameter in the Create/Update Item(s) module.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open_source_point_of_sale","vendor":"opensourcepos"}],"cvss":{"score":7.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A Cross-site scripting (XSS) vulnerability in Create/Update Item(s) Module in Open Source Point of Sale v3.4.1 allows remote attackers to inject arbitrary web script or HTML via the \"name\" parameter.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Cross-site scripting in n/a","id":"CVE-2025-66921","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-66923"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-66918"},"products":["n/a"],"published":"2025-12-17","related":[{"cvss_score":8.8,"headline":"Open Source Point of Sale is Vulnerable to SQL Injection Through its Item Search Functionality","id":"CVE-2026-32888","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":8.8,"headline":"Path traversal in n/a","id":"CVE-2026-26746","kev_date_added":null,"published":"2026-02-20"},{"cvss_score":8.8,"headline":"opensourcepos has Cross-Site Request Forgery vulnerability that leads to Unauthorized Administrator Creation","id":"CVE-2025-68434","kev_date_added":null,"published":"2025-12-17"},{"cvss_score":8.1,"headline":"opensourcepos has a Cross-site Scripting vulnerability","id":"CVE-2025-68147","kev_date_added":null,"published":"2025-12-17"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2025-63800","kev_date_added":null,"published":"2025-11-18"},{"cvss_score":7.4,"headline":"Command injection in n/a","id":"CVE-2025-70093","kev_date_added":null,"published":"2026-02-13"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-12-17","vendors":["n/a"]},"summary":"Remote attackers can inject arbitrary web script or HTML via the name parameter in the Create/Update Item(s) module.","url":"https://insights.sbomify.com/CVE-2025-66921/"}
