An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-3985 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apereo.cas:cas-management-webapp-support (Maven): affected all versions up to 5.2.6; no fix listed\n- org.apereo.cas:cas-management-webapp-support (Maven): affected all versions up to 5.2.6; no fix listed\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-2025-3985/ (Markdown: https://insights.sbomify.com/CVE-2025-3985/index.md)","id":"CVE-2025-3985","markdown":"https://insights.sbomify.com/CVE-2025-3985/index.md","name":"CVE-2025-3985","record":{"aliases":["GHSA-8rx4-fxq5-vj4v"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apereo CAS","requires_auth":"high_privilege","summary":"Remote attackers can cause denial of service in Apereo CAS by exploiting inefficient regular expression complexity in the ResponseEntity function.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"central_authentication_service","vendor":"apereo"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"A vulnerability was found in Apereo CAS 5.2.6.
