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-2022-4137 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.keycloak:keycloak-parent (Maven): affected all versions; fixed in 20.0.5\n- org.keycloak:keycloak-parent (Maven): affected all versions; fixed in 20.0.5\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-2022-4137/ (Markdown: https://insights.sbomify.com/CVE-2022-4137/index.md)","id":"CVE-2022-4137","markdown":"https://insights.sbomify.com/CVE-2022-4137/index.md","name":"CVE-2022-4137","record":{"aliases":["GHSA-9hhc-pj4w-w5rv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak SSO","requires_auth":"none","summary":"Reflected XSS in Keycloak's OAuth endpoint allows attackers to inject scripts via malicious links, potentially compromising user data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"keycloak","vendor":"redhat"},{"product":"single_sign-on","vendor":"redhat"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-81","name":"Improper Neutralization of Script in an Error Message Web Page"}],"description":"A reflected cross-site scripting (XSS) vulnerability was found in the 'oob' OAuth endpoint due to incorrect null-byte handling.
