CVE-2026-108755: Allocation of Resources Without Limits or Throttling in hatchet-dev hatchet
Description
Hatchet through 0.110.5 contains an allocation of resources without limits vulnerability that allows unauthenticated attackers to exhaust memory via the SNS ingestion endpoint. Attackers can send arbitrarily large or concurrent request bodies to POST /api/v1/sns/{tenant}/{event} with any UUID, which the SnsUpdate handler buffers before signature verification, degrading availability.

Technical Analysis
Hatchet versions up to 0.110.5 contain a vulnerability where the SNS ingestion endpoint (/api/v1/sns/{tenant}/{event}) accepts arbitrarily large or concurrent POST request bodies with any UUID. The SnsUpdate handler buffers these requests before verifying their signatures, leading to unbounded memory allocation. This lack of resource limits or throttling can be exploited by unauthenticated attackers to exhaust memory resources and degrade service availability.
Potential Impact
The vulnerability allows unauthenticated attackers to cause a denial of service by exhausting memory resources on the affected system. This degrades the availability of the hatchet service by overwhelming it with large or concurrent requests to the SNS ingestion endpoint.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider implementing external rate limiting or request size restrictions at the network or application gateway level to mitigate potential exploitation.
