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-2022-29496 exists.\n\nAffected product: Blynk-Library. 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-2022-29496/ (Markdown: https://insights.sbomify.com/CVE-2022-29496/index.md)","id":"CVE-2022-29496","markdown":"https://insights.sbomify.com/CVE-2022-29496/index.md","name":"CVE-2022-29496","record":{"aliases":["GHSA-4v52-cfm2-5xvm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Blynk IoT library","requires_auth":"none","summary":"A stack-based buffer overflow in the Blynk library allows remote attackers to execute arbitrary commands via a specially crafted network request.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"blynk-library","vendor":"blynk"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow vulnerability exists in the BlynkConsole.h runCommand functionality of Blynk -Library v1.0.1.
