A vulnerability (CVE-2026-14742) was found in langchain-ai langgraph up to version 1.2.4, where the _freeze function in the Task Result Cache (a system that stores computed task results to avoid recalculating them) uses a weak hash when processing the default_cache_key argument. This could potentially be exploited remotely, though the attack requires significant technical skill and is considered difficult to execute.
