An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-rvg8-pwq2-xj7q in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- base64url (npm): affected all versions; fixed in 3.0.0\n- base64url (npm): affected all versions; fixed in 3.0.0\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/GHSA-rvg8-pwq2-xj7q/ (Markdown: https://insights.sbomify.com/GHSA-rvg8-pwq2-xj7q/index.md)","id":"GHSA-rvg8-pwq2-xj7q","markdown":"https://insights.sbomify.com/GHSA-rvg8-pwq2-xj7q/index.md","name":"GHSA-rvg8-pwq2-xj7q","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js base64url library","requires_auth":"none","summary":"An out-of-bounds read in the base64url library allows attackers to disclose sensitive memory contents when processing numeric inputs.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Versions of `base64url` before 3.0.0 are vulnerable to to out-of-bounds reads as it allocates uninitialized Buffers when number is passed in input on Node.js 4.x and below.\n\n## Recommendation\n\nUpdate to version 3.0.0 or later.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Out-of-bounds Read in base64url","id":"GHSA-rvg8-pwq2-xj7q","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"npm","product":null,"products":[],"type":"information_disclosure","year":"2020"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"npm","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"base64url","purl":null,"source":"GHSA-rvg8-pwq2-xj7q"},{"ecosystem":"npm","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"base64url","purl":"pkg:npm/base64url","source":"GHSA-rvg8-pwq2-xj7q"}],"products":null,"published":"2020-09-01","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An out-of-bounds read in the base64url library allows attackers to disclose sensitive memory contents when processing numeric inputs.","url":"https://insights.sbomify.com/GHSA-rvg8-pwq2-xj7q/"}
