An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4249 in the wild and no public exploit code.\n\nAffected product: Wso2 Api Manager. 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-2026-4249/ (Markdown: https://insights.sbomify.com/CVE-2026-4249/index.md)","id":"CVE-2026-4249","markdown":"https://insights.sbomify.com/CVE-2026-4249/index.md","name":"CVE-2026-4249","record":{"aliases":["GHSA-7469-8h9r-c5xc"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WSO2 API Manager","requires_auth":"none","summary":"Unauthenticated attackers can cause persistent denial of service in WSO2 API Gateway products by sending malicious JSON payloads to throttling events.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WSO2","cpe":[{"product":"api_control_plane","vendor":"wso2"},{"product":"api_manager","vendor":"wso2"},{"product":"traffic_manager","vendor":"wso2"},{"product":"universal_gateway","vendor":"wso2"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-707","name":"Improper Neutralization"}],"description":"The throttling event handling mechanism in multiple WSO2 products accepts user-supplied JSON payloads without sufficient validation of their structure and content.
