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-2020-8215 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- canvas (npm): affected all versions; fixed in 1.6.11\n- canvas (npm): affected all versions; fixed in 1.6.11\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-2020-8215/ (Markdown: https://insights.sbomify.com/CVE-2020-8215/index.md)","id":"CVE-2020-8215","markdown":"https://insights.sbomify.com/CVE-2020-8215/index.md","name":"CVE-2020-8215","record":{"aliases":["GHSA-73rg-x683-m3qw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js canvas library","requires_auth":"none","summary":"A buffer overflow in the node-canvas library allows attackers to execute arbitrary code or cause denial of service via malicious images.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"canvas","vendor":"automattic"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow is present in canvas version \u003c= 1.6.9, which could lead to a Denial of Service or execution of arbitrary code when it processes a user-provided image.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Buffer overflow in canvas","id":"CVE-2020-8215","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Information disclosure in Pulse Connect Secure","id":"CVE-2020-8216"},"packages":[{"ecosystem":"npm","fixed":["1.6.11"],"introduced":["0"],"last_affected":[],"package":"canvas","purl":null,"source":"GHSA-73rg-x683-m3qw"},{"ecosystem":"npm","fixed":["1.6.11"],"introduced":["0"],"last_affected":[],"package":"canvas","purl":"pkg:npm/canvas","source":"GHSA-73rg-x683-m3qw"}],"prev":{"headline":"Path traversal in servey","id":"CVE-2020-8214"},"products":["node-canvas"],"published":"2020-07-20","related":[],"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":"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A buffer overflow in the node-canvas library allows attackers to execute arbitrary code or cause denial of service via malicious images.","url":"https://insights.sbomify.com/CVE-2020-8215/"}
