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-2020-10748 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 10.0.2\n- org.keycloak:keycloak-parent (Maven): affected all versions; fixed in 10.0.2\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-2020-10748/ (Markdown: https://insights.sbomify.com/CVE-2020-10748/index.md)","id":"CVE-2020-10748","markdown":"https://insights.sbomify.com/CVE-2020-10748/index.md","name":"CVE-2020-10748","record":{"aliases":["GHSA-hgpg-593r-hhvp"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"none","summary":"An XSS vulnerability in Keycloak's data filter allows attackers to execute scripts or conduct further attacks via data URLs.","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":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/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's data filter, in version 10.0.1, where it allowed the processing of data URLs in some circumstances.
