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-2026-5724 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- go.temporal.io/server (Go): affected all versions; fixed in 1.28.4, 1.29.6, 1.30.4\n- go.temporal.io/server (Go): affected all versions; fixed in 1.28.4\n- go.temporal.io/server (Go): affected all versions; fixed in 1.28.4\n- go.temporal.io/server (Go): affected from 1.29.0-135.0; fixed in 1.29.6\n- go.temporal.io/server (Go): affected from 1.29.0-135.0; fixed in 1.29.6\n- go.temporal.io/server (Go): affected from 1.30.0-143.0; fixed in 1.30.4\n- go.temporal.io/server (Go): affected from 1.30.0-143.0; fixed in 1.30.4\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-2026-5724/ (Markdown: https://insights.sbomify.com/CVE-2026-5724/index.md)","id":"CVE-2026-5724","markdown":"https://insights.sbomify.com/CVE-2026-5724/index.md","name":"CVE-2026-5724","record":{"aliases":["CLEANSTART-2026-AW40978","CLEANSTART-2026-ED75868","CLEANSTART-2026-HK90516","ECHO-0bd4-bfde-70a9","GHSA-q98v-9f9w-f49q","GO-2026-5578","MINI-4vq3-gjcq-2v4f","MINI-53g3-8j8p-hrg5","MINI-8wpp-fm4r-3gq6","MINI-fjph-m667-f7cf","MINI-fmmc-w32v-p3hw","MINI-hpj9-r8w3-p3vc","MINI-jp2w-3rgm-85vc","MINI-phwj-xf6g-pmcg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Temporal workflow server","requires_auth":"none","summary":"An attacker with network access can bypass authentication on the streaming replication endpoint to potentially exfiltrate data if replication is configured.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Temporal","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:L/SI:N/SA:N/S:N/AU:N/R:U/RE:L","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"The frontend gRPC server's streaming interceptor chain did not include the authorization interceptor. When a ClaimMapper and Authorizer are configured, unary RPCs enforce authentication and authorization, but the streaming AdminService/StreamWorkflowReplicationMessages endpoint accepted requests without credentials. This endpoint is registered on the same port as WorkflowService and cannot be disabled independently. An attacker with network access to the frontend port could open the replication stream without authentication. Data exfiltration is possible, but  only when a configured replication target is correctly configured and the attacker has knowledge of the cluster configuration, as the history service validates cluster IDs and peer membership before returning replication data.\n\nThe fix was applied per release line: it is present in 1.28.4, 1.29.6, 1.30.4, 1.31.2, and 1.32.0 and later releases on each line.
