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-2026-121652/ (Markdown: https://insights.sbomify.com/CVE-2026-121652/index.md)","id":"CVE-2026-121652","markdown":"https://insights.sbomify.com/CVE-2026-121652/index.md","name":"CVE-2026-121652","record":{"aliases":["GHSA-34v3-xxqp-g5g9"],"analysis":null,"analysis_generated_by":null,"assigner":"AMZN","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/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":"Cross-site scripting (XSS) issue in AWS Amplify maplibre-gl-js-amplify before 4.0.3 might allow remote authenticated users to inject arbitrary web script or HTML via the (1) title, (2) address, or (3) place_name property in GeoJSON feature data rendered by popupRender, or the (4) geofenceId value rendered in AmplifyGeofenceControl.\n\nTo remediate this issue, users should upgrade to 4.0.3 or later.","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":"Stored cross-site scripting (XSS) in AWS Amplify maplibre-gl-js-amplify popup rendering","id":"CVE-2026-121652","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"SQL injection in the Core of Ivanti Endpoint Manager before version 2024 SU8 allows a remote unauthenticated attacker to achieve remote code execution.","id":"CVE-2026-121653"},"nickname":null,"packages":[],"prev":{"headline":"WatchGuard AuthPoint Gateway Capture-replay Allows Unauthorized Administrative Actions","id":"CVE-2026-121640"},"products":["maplibre-gl-js-amplify"],"published":"2026-11-03","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":"2026-11-03","vendors":["AWS"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-121652/"}
