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."}],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":2.3,"vectorString":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","baseSeverity":"LOW"}},{"cvssV3_1":{"version":"3.1","baseScore":3.1,"vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:P/RL:X/RC:R","baseSeverity":"LOW"}},{"cvssV3_0":{"version":"3.0","baseScore":3.1,"vectorString":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:P/RL:X/RC:R","baseSeverity":"LOW"}},{"cvssV2_0":{"version":"2.0","baseScore":2.1,"vectorString":"AV:N/AC:H/Au:S/C:P/I:N/A:N/E:POC/RL:ND/RC:UR"}}],"timeline":[{"time":"2026-07-04T00:00:00.000Z","lang":"en","value":"Advisory disclosed"},{"time":"2026-07-04T02:00:00.000Z","lang":"en","value":"VulDB entry created"},{"time":"2026-07-04T14:51:42.000Z","lang":"en","value":"VulDB entry last update"}],"credits":[{"lang":"en","value":"Dem0 (VulDB User)","type":"reporter"},{"lang":"en","value":"VulDB CNA Team","type":"coordinator"}],"references":[{"url":"https://vuldb.com/vuln/376328","name":"VDB-376328 | langchain-ai langgraph Task Result Cache _cache.py _freeze weak hash","tags":["vdb-entry","technical-description"]},{"url":"https://vuldb.com/vuln/376328/cti","name":"VDB-376328 | CTI Indicators (IOB, IOC, TTP, IOA)","tags":["signature","permissions-required"]},{"url":"https://vuldb.com/cve/CVE-2026-14742","name":"CVE-2026-14742 | CVE Analysis and Report","tags":["third-party-advisory"]},{"url":"https://vuldb.com/submit/849217","name":"Submit #849217 | langchain-ai langgraph 1.2.4 Use of Weak Hash","tags":["third-party-advisory"]},{"url":"https://github.com/langchain-ai/langgraph/issues/8009","tags":["exploit","issue-tracking"]},{"url":"https://github.com/langchain-ai/langgraph/pull/8069","tags":["issue-tracking","patch"]},{"url":"https://github.com/langchain-ai/langgraph/","tags":["product"]}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-06T17:59:36.498934Z","id":"CVE-2026-14742","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-06T17:59:43.776Z"}}]}}
