Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-4794 and fix it if it is affected.\n\nWhat it is: CVE-2026-4794 is a low-severity cross-site scripting vulnerability in PaperCut NG/MF, published on 31 Mar 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-4794 in the wild and no public exploit code.\n\nAffected product: PaperCut NG/MF. 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-2026-4794/ (Markdown: https://insights.sbomify.com/CVE-2026-4794/index.md)","id":"CVE-2026-4794","markdown":"https://insights.sbomify.com/CVE-2026-4794/index.md","name":"CVE-2026-4794","record":{"aliases":["GHSA-m6wx-rxrp-cc9p"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PaperCut NG/MF","requires_auth":"low_privilege","summary":"Authenticated administrators can inject scripts via UI fields to compromise other admin sessions or perform unauthorized actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PaperCut","cpe":[{"product":"papercut_mf","vendor":"papercut"},{"product":"papercut_ng","vendor":"papercut"}],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:N/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":"Multiple cross-site scripting (XSS) vulnerabilities in PaperCut NG/MF before 25.0.10 allow authenticated administrator users to inject arbitrary web script or HTML code via different UI fields.
