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-2026-3962 exists.\n\nAffected product: Jcharis Machine-Learning-Web-Apps. 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-2026-3962/ (Markdown: https://insights.sbomify.com/CVE-2026-3962/index.md)","id":"CVE-2026-3962","markdown":"https://insights.sbomify.com/CVE-2026-3962/index.md","name":"CVE-2026-3962","record":{"aliases":["GHSA-gj88-g2mg-f9rr"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Machine Learning Web Apps","requires_auth":"none","summary":"Remote attackers can execute arbitrary scripts via cross-site scripting in the Jinja2 template handler of the Machine-Learning-Web-Apps application.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A vulnerability was identified in Jcharis Machine-Learning-Web-Apps up to a6996b634d98ccec4701ac8934016e8175b60eb5.
