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-2020-8176 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @shopify/koa-shopify-auth (npm): affected from 3.1.61; fixed in 3.1.63\n- @shopify/koa-shopify-auth (npm): affected from 3.1.61; fixed in 3.1.63\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-2020-8176/ (Markdown: https://insights.sbomify.com/CVE-2020-8176/index.md)","id":"CVE-2020-8176","markdown":"https://insights.sbomify.com/CVE-2020-8176/index.md","name":"CVE-2020-8176","record":{"aliases":["GHSA-jqh7-w5pr-cr56"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js authentication library","requires_auth":"none","summary":"An attacker can inject JavaScript payloads via the shop parameter in the koa-shopify-auth library, potentially executing code in the victim's browser.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"koa-shopify-auth","vendor":"shopify"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A cross-site scripting vulnerability exists in koa-shopify-auth v3.1.61-v3.1.62 that allows an attacker to inject JS payloads into the `shop` parameter on the `/shopify/auth/enable_cookies` endpoint.","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":"Cross-site scripting in @shopify/koa-shopify-auth","id":"CVE-2020-8176","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Path traversal in https://github.com/curl/curl","id":"CVE-2020-8177"},"packages":[{"ecosystem":"npm","fixed":["3.1.63"],"introduced":["3.1.61"],"last_affected":[],"package":"@shopify/koa-shopify-auth","purl":null,"source":"GHSA-jqh7-w5pr-cr56"},{"ecosystem":"npm","fixed":["3.1.63"],"introduced":["3.1.61"],"last_affected":[],"package":"@shopify/koa-shopify-auth","purl":"pkg:npm/%40shopify/koa-shopify-auth","source":"GHSA-jqh7-w5pr-cr56"}],"prev":{"headline":"Uncontrolled resource consumption in jpeg-js","id":"CVE-2020-8175"},"products":["koa-shopify-auth"],"published":"2020-07-02","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":"An attacker can inject JavaScript payloads via the shop parameter in the koa-shopify-auth library, potentially executing code in the victim's browser.","url":"https://insights.sbomify.com/CVE-2020-8176/"}
