An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47972 exists.\n\nAffected product: sticky-notes-color-widgets Sticky Notes Color Widgets. 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-2021-47972/ (Markdown: https://insights.sbomify.com/CVE-2021-47972/index.md)","id":"CVE-2021-47972","markdown":"https://insights.sbomify.com/CVE-2021-47972/index.md","name":"CVE-2021-47972","record":{"aliases":["GHSA-6vpc-p46x-xmf7"],"analysis":{"component_type":"mobile_application","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Sticky Notes app","requires_auth":"none","summary":"Attackers can crash the Sticky Notes \u0026 Color Widgets application by inputting excessively long character strings into note fields.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"Sticky Notes \u0026 Color Widgets 1.4.2 contains a denial of service vulnerability that allows attackers to crash the application by creating notes with excessively long character strings.
