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-2023-6291 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-2023-6291/ (Markdown: https://insights.sbomify.com/CVE-2023-6291/index.md)","id":"CVE-2023-6291","markdown":"https://insights.sbomify.com/CVE-2023-6291/index.md","name":"CVE-2023-6291","record":{"aliases":["GHSA-mpwq-j3xf-7m5w"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Identity and Access Management","requires_auth":"none","summary":"Attackers can bypass redirect_uri validation to steal access tokens and impersonate users in Keycloak deployments.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"keycloak","vendor":"redhat"},{"product":"migration_toolkit_for_applications","vendor":"redhat"},{"product":"openshift_container_platform","vendor":"redhat"},{"product":"openshift_container_platform_for_ibm_z","vendor":"redhat"},{"product":"openshift_container_platform_for_linuxone","vendor":"redhat"},{"product":"openshift_container_platform_for_power","vendor":"redhat"},{"product":"single_sign-on","vendor":"redhat"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"A flaw was found in the redirect_uri validation logic in Keycloak.
