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-2022-39974 exists.\n\nAffected packages and fixed versions:\n- pywasm3 (PyPI): affected all versions; no fix listed\n- pywasm3 (PyPI): affected all versions up to 0.5.0; no fix listed\n- pywasm3 (PyPI): affected all versions up to 0.5.0; no fix listed\n- wasm3 (crates.io): affected all versions up to 0.5.0; no fix listed\n- wasm3 (crates.io): affected all versions up to 0.5.0; no fix listed\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-2022-39974/ (Markdown: https://insights.sbomify.com/CVE-2022-39974/index.md)","id":"CVE-2022-39974","markdown":"https://insights.sbomify.com/CVE-2022-39974/index.md","name":"CVE-2022-39974","record":{"aliases":["GHSA-crf8-h2wq-2h9x","PYSEC-2022-43058"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WASM3 runtime library","requires_auth":"none","summary":"A segmentation fault in the WASM3 library allows attackers to cause a denial of service via crafted WebAssembly instructions.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wasm3","vendor":"wasm3_project"}],"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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"WASM3 v0.5.0 was discovered to contain a segmentation fault via the component op_Select_i32_srs in wasm3/source/m3_exec.h.","ecosystems":["PyPI","crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"WASM3 Improper Input Validation vulnerability","id":"CVE-2022-39974","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":5,"n_references":1,"next":{"headline":"Liferay Portal Missing Authorization vulnerability","id":"CVE-2022-39975"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":[],"package":"pywasm3","purl":"pkg:pypi/pywasm3","source":"PYSEC-2022-43058"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0"],"package":"pywasm3","purl":null,"source":"GHSA-crf8-h2wq-2h9x"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0"],"package":"pywasm3","purl":"pkg:pypi/pywasm3","source":"GHSA-crf8-h2wq-2h9x"},{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["0.5.0"],"package":"wasm3","purl":null,"source":"GHSA-crf8-h2wq-2h9x"},{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["0.5.0"],"package":"wasm3","purl":"pkg:cargo/wasm3","source":"GHSA-crf8-h2wq-2h9x"}],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2022-39960"},"products":["n/a"],"published":"2022-09-20","related":[{"cvss_score":9.8,"headline":"pywasm3 contains a heap buffer overflow which leads to segmentation fault","id":"CVE-2024-34249","kev_date_added":null,"published":"2024-05-06"},{"cvss_score":8.4,"headline":"pywasm3 has an Invalid Memory Read, Leading to DoS and Potential Code Execution","id":"CVE-2024-27528","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":8.4,"headline":"wasm3 uncontrolled memory allocation vulnerability","id":"CVE-2024-27529","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":8.4,"headline":"pywasm3 contains a Use-After-Free in ForEachModule","id":"CVE-2024-27530","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":7.8,"headline":"Buffer overflow in wasm3","id":"CVE-2022-28990","kev_date_added":null,"published":"2022-05-20"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-27527","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2024-34246","kev_date_added":null,"published":"2024-05-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-28","vendors":["n/a"]},"summary":"A segmentation fault in the WASM3 library allows attackers to cause a denial of service via crafted WebAssembly instructions.","url":"https://insights.sbomify.com/CVE-2022-39974/"}
