An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-42839 in the wild and no public exploit code.\n\nAffected product: Frappe ERPNext. 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-2026-42839/ (Markdown: https://insights.sbomify.com/CVE-2026-42839/index.md)","id":"CVE-2026-42839","markdown":"https://insights.sbomify.com/CVE-2026-42839/index.md","name":"CVE-2026-42839","record":{"aliases":["GHSA-hc32-c5xw-9f2m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"ERPNext","requires_auth":"high_privilege","summary":"Authenticated users can inject malicious scripts into item fields, leading to stored XSS execution in the POS interface for other operators.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fluid Attacks","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"An authenticated ERPNext user with Item record edit permissions can persist arbitrary HTML/JavaScript in the item_name, description, or image fields of an Item and trigger unescaped rendering in the Point of Sale (POS) cart interface for every operator who adds that item to a transaction.This issue affects ERPNext: 16.16.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"ERPNext 16.16.0 - Stored XSS in POS cart item rendering","id":"CVE-2026-42839","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"ERPNext 16.16.0 - Stored XSS in POS customer section via unescaped template literals","id":"CVE-2026-42840"},"packages":[],"prev":{"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2026-42838"},"products":["ERPNext"],"published":"2026-06-03","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-03","vendors":["Frappe"]},"summary":"Authenticated users can inject malicious scripts into item fields, leading to stored XSS execution in the POS interface for other operators.","url":"https://insights.sbomify.com/CVE-2026-42839/"}
