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-2020-8910 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- google-closure-library (npm): affected all versions; fixed in 20200315.0.0\n- google-closure-library (npm): affected all versions; fixed in 20200315.0.0\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-2020-8910/ (Markdown: https://insights.sbomify.com/CVE-2020-8910/index.md)","id":"CVE-2020-8910","markdown":"https://insights.sbomify.com/CVE-2020-8910/index.md","name":"CVE-2020-8910","record":{"aliases":["GHSA-vh5w-fg69-rc8m","UBUNTU-CVE-2020-8910"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript utility library","requires_auth":"none","summary":"An attacker can exploit a URL parsing flaw in the Google Closure Library to bypass security checks by returning incorrect authority information.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"closure_library","vendor":"google"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-625","name":"Permissive Regular Expression"}],"description":"A URL parsing issue in goog.uri of the Google Closure Library versions up to and including v20200224 allows an attacker to send malicious URLs to be parsed by the library and return the wrong authority.
