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-g3qw-9pgp-xpj4 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- njwt (npm): affected all versions; fixed in 1.0.0\n- njwt (npm): affected all versions; fixed in 1.0.0\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-g3qw-9pgp-xpj4/ (Markdown: https://insights.sbomify.com/GHSA-g3qw-9pgp-xpj4/index.md)","id":"GHSA-g3qw-9pgp-xpj4","markdown":"https://insights.sbomify.com/GHSA-g3qw-9pgp-xpj4/index.md","name":"GHSA-g3qw-9pgp-xpj4","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js JWT library","requires_auth":"none","summary":"An out-of-bounds read in the njwt library allows attackers to expose sensitive information or cause denial of service via crafted input.","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 `njwt` prior to 1.0.0 are vulnerable to out-of-bounds reads when a number is passed into the `base64urlEncode` function. \n\nOn Node.js 6.x or lower this can expose sensitive information and on any other version of Node.js this creates a Denial of Service vulnerability.\n\n## Recommendation\n\nUpgrade to version 1.0.0.","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 njwt","id":"GHSA-g3qw-9pgp-xpj4","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":["1.0.0"],"introduced":["0"],"last_affected":[],"package":"njwt","purl":null,"source":"GHSA-g3qw-9pgp-xpj4"},{"ecosystem":"npm","fixed":["1.0.0"],"introduced":["0"],"last_affected":[],"package":"njwt","purl":"pkg:npm/njwt","source":"GHSA-g3qw-9pgp-xpj4"}],"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 njwt library allows attackers to expose sensitive information or cause denial of service via crafted input.","url":"https://insights.sbomify.com/GHSA-g3qw-9pgp-xpj4/"}
