An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-1941 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- protobuf (PyPI): affected all versions; fixed in 3.18.3, 3.19.5, 3.20.2, 4.21.6\n- protobuf (PyPI): affected all versions; fixed in 3.18.3\n- protobuf (PyPI): affected all versions; fixed in 3.18.3\n- protobuf (PyPI): affected from 3.19.0; fixed in 3.19.5\n- protobuf (PyPI): affected from 3.19.0; fixed in 3.19.5\n- protobuf (PyPI): affected from 3.20.0; fixed in 3.20.2\n- protobuf (PyPI): affected from 3.20.0; fixed in 3.20.2\n- protobuf (PyPI): affected from 4.0.0; fixed in 4.21.6\n- protobuf (PyPI): affected from 4.0.0; fixed in 4.21.6\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-2022-1941/ (Markdown: https://insights.sbomify.com/CVE-2022-1941/index.md)","id":"CVE-2022-1941","markdown":"https://insights.sbomify.com/CVE-2022-1941/index.md","name":"CVE-2022-1941","record":{"aliases":["ALSA-2025:7138","AZL-13172","AZL-13174","AZL-25856","AZL-35018","AZL-35125","AZL-35147","AZL-38908","AZL-39031","AZL-39061","CLEANSTART-2026-DG47238","CLEANSTART-2026-PU59944","CLSA-2025-1758039948","CLSA-2026-1770164040","DEBIAN-CVE-2022-1941","GHSA-8gq9-2x98-w8hf","PYSEC-2026-899","RHSA-2025:7138","RLSA-2025:7138","UBUNTU-CVE-2022-1941"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Protocol Buffers library","requires_auth":"none","summary":"Attackers can cause denial of service in applications using Protocol Buffers by sending specially crafted messages that trigger out-of-memory failures.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"protobuf-cpp","vendor":"google"},{"product":"protobuf-python","vendor":"google"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1286","name":"Improper Validation of Syntactic Correctness of Input"}],"description":"A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures.
