A vulnerability was determined in langchain-ai langgraph up to 1.2.4. The affected element is the function _freeze of the file libs/langgraph/langgraph/_internal/_cache.py of the component Task Result Cache. This manipulation of the argument default_cache_key causes use of weak hash. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is described as difficult. The exploit has been publicly disclosed and may be utilized. The pull request to fix this issue awaits acceptance.

A flaw was found in langgraph. A remote attacker could exploit this vulnerability by manipulating the `default_cache_key` argument within the `_freeze` function of the Task Result Cache component. This manipulation leads to the use of a weak hash, which may result in limited information disclosure.

This flaw in langgraph, rated as Low impact, could lead to limited information disclosure. Exploitation requires a remote attacker to manipulate the `default_cache_key` argument, which is considered difficult due to the high complexity of the attack. The vulnerability's limited scope and challenging exploitability reduce its overall risk in typical Red Hat deployments. Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
