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-2025-10503 in the wild and no public exploit code.\n\nAffected product: Wso2 Identity Server. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2025-10503/ (Markdown: https://insights.sbomify.com/CVE-2025-10503/index.md)","id":"CVE-2025-10503","markdown":"https://insights.sbomify.com/CVE-2025-10503/index.md","name":"CVE-2025-10503","record":{"aliases":["GHSA-6pqq-8j74-wgg5"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Identity Server","requires_auth":"none","summary":"Attackers can inject malicious scripts via the authentication endpoint to steal data or modify the UI, though session hijacking is prevented by httpOnly cookies.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WSO2","cpe":[{"product":"identity_server","vendor":"wso2"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","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":"The authentication endpoint accepts user-supplied input without enforcing expected validation constraints, leading to a lack of proper output encoding.
