Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54746 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hatchet-dev/hatchet (Go): affected from 0.40.0; fixed in 0.91.2\n- github.com/hatchet-dev/hatchet (Go): affected from 0.40.0; fixed in 0.91.2\n- github.com/hatchet-dev/hatchet (Go): affected from 0.40.0; fixed in 0.91.2\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-2026-54746/ (Markdown: https://insights.sbomify.com/CVE-2026-54746/index.md)","id":"CVE-2026-54746","markdown":"https://insights.sbomify.com/CVE-2026-54746/index.md","name":"CVE-2026-54746","record":{"aliases":["GHSA-8x7x-83cf-c3pg","GO-2026-6309"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Hatchet task orchestrator","requires_auth":"low_privilege","summary":"Authenticated users can modify or disconnect other tenants' workers by guessing UUIDs, causing cross-tenant integrity issues and denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Hatchet is a platform for orchestrating background tasks, AI agents, and durable workflows at scale. From 0.40.0 until 0.91.1, the Dispatcher gRPC service does not verify that a request's worker ID belongs to the tenant identified by the bearer-token context in Dispatcher/UpsertWorkerLabels and Dispatcher/Unsubscribe. An authenticated owner of any tenant who guesses another tenant's worker UUID can overwrite that worker's affinity labels or disconnect the worker from the dispatcher. This can cause cross-tenant integrity impact and denial of service on multi-tenant Hatchet Cloud or shared self-hosted deployments. Single-tenant deployments are not practically affected because the attacker and target tenant are the same.
