Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-6134 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 23.0.3\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 23.0.3\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-2023-6134/ (Markdown: https://insights.sbomify.com/CVE-2023-6134/index.md)","id":"CVE-2023-6134","markdown":"https://insights.sbomify.com/CVE-2023-6134/index.md","name":"CVE-2023-6134","record":{"aliases":["GHSA-cvg2-7c3j-g36j"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak SSO","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary scripts in victim browsers via crafted OIDC redirect URIs, potentially leading to session hijacking or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"keycloak","vendor":"redhat"},{"product":"openshift_container_platform","vendor":"redhat"},{"product":"openshift_container_platform_for_power","vendor":"redhat"},{"product":"openshift_container_platform_ibm_z_systems","vendor":"redhat"},{"product":"single_sign-on","vendor":"redhat"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token.
