An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-49594 exists.\n\nAffected product: instipod DuoUniversalKeycloakAuthenticator. 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-2023-49594/ (Markdown: https://insights.sbomify.com/CVE-2023-49594/index.md)","id":"CVE-2023-49594","markdown":"https://insights.sbomify.com/CVE-2023-49594/index.md","name":"CVE-2023-49594","record":{"aliases":["GHSA-23qf-mx2g-p3gq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak authentication plugin","requires_auth":"high_privilege","summary":"A crafted HTTP request during Keycloak login via the DuoUniversalKeycloakAuthenticator plugin can disclose sensitive information to an attacker.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"duouniversalkeycloakauthenticator","vendor":"michaelkelly"}],"cvss":{"score":4.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-201","name":"Insertion of Sensitive Information Into Sent Data"}],"description":"An information disclosure vulnerability exists in the challenge functionality of instipod DuoUniversalKeycloakAuthenticator 1.0.7 plugin.
