Prior to 0.3.85 and 1.3.3, LangChain contains older runtime code paths that deserialize run inputs, run outputs, or other application-controlled payloads using overly broad object allowlists. These paths may call load() with allowed_objects=\"all\". This does not enable arbitrary Python object deserialization, but it does allow any trusted LangChain-serializable object to be revived, which is broader than these runtime paths require. As a result, attacker-supplied LangChain serialized constructor dictionaries may cause trusted runtime paths to instantiate classes with untrusted constructor arguments. This vulnerability is fixed in 0.3.85 and 1.3.3.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-44843","reference_id":"","reference_type":"","scores":[{"value":"0.00045","scoring_system":"epss","scoring_elements":"0.14347","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00045","scoring_system":"epss","scoring_elements":"0.14227","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00045","scoring_system":"epss","scoring_elements":"0.14346","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-44843"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44843","reference_id":"","reference_type":"","scores":[{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44843"},{"reference_url":"https://github.com/advisories/GHSA-pjwx-r37v-7724","reference_id":"GHSA-pjwx-r37v-7724","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-pjwx-r37v-7724"},{"reference_url":"https://github.com/langchain-ai/langchain/security/advisories/GHSA-pjwx-r37v-7724","reference_id":"GHSA-pjwx-r37v-7724","reference_type":"","scores":[{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-05-27T14:06:50Z/"}],"url":"https://github.com/langchain-ai/langchain/security/advisories/GHSA-pjwx-r37v-7724"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/376084?format=json","purl":"pkg:pypi/langchain-core@0.3.85","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/langchain-core@0.3.85"},{"url":"http://public2.vulnerablecode.io/api/packages/376083?format=json","purl":"pkg:pypi/langchain-core@1.3.3","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/langchain-core@1.3.3"}],"aliases":["CVE-2026-44843","GHSA-pjwx-r37v-7724"],"risk_score":4.0,"exploitability":"0.5","weighted_severity":"8.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-sjb2-w7tj-fqh2"}],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/langchain-core@0.3.85"}
