An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-87961 in the wild and no public exploit code.\n\nAffected product: schreibfaul1 ESP32-audioI2S. 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-2026-87961/ (Markdown: https://insights.sbomify.com/CVE-2026-87961/index.md)","id":"CVE-2026-87961","markdown":"https://insights.sbomify.com/CVE-2026-87961/index.md","name":"CVE-2026-87961","record":{"aliases":["GHSA-p79f-7v67-j5f7"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"ESP32 audio library","requires_auth":"none","summary":"Attackers can crash ESP32 devices or leak heap memory by sending malicious MP3 files or audio streams to the ESP32-audioI2S library.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"ESP32-audioI2S versions 3.4.4 through 4.0.0 contain a heap-based out-of-bounds read vulnerability in the read_ID3_Header function due to a shadowed length parameter in ID3 synchronized-lyrics processing.
