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-2026-30048 exists.\n\nAffected packages and fixed versions:\n- @developer.notchatbot/webchat (npm): affected all versions up to 1.5.0; no fix listed\n- @developer.notchatbot/webchat (npm): affected all versions up to 1.5.0; no fix listed\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-2026-30048/ (Markdown: https://insights.sbomify.com/CVE-2026-30048/index.md)","id":"CVE-2026-30048","markdown":"https://insights.sbomify.com/CVE-2026-30048/index.md","name":"CVE-2026-30048","record":{"aliases":["GHSA-w3vx-52j6-9fjp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"NotChatbot WebChat widget","requires_auth":"low_privilege","summary":"Attackers can inject arbitrary JavaScript into chat history via unsanitized input, leading to code execution when history is reloaded.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","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":"A stored cross-site scripting (XSS) vulnerability exists in the NotChatbot WebChat widget thru 1.4.4.

This allows an attacker to inject arbitrary JavaScript code which is executed when the chat history is reloaded.
