As of 5 Nov 2026, the latest release of langchain on PyPI is 1.4.9. No published advisory (OSV) matches 1.4.9; 23 more affect older versions only. No field reports on 1.4.9 yet. Security status: clear. pypi:langchain **1.4.9**latest on PyPI **0**advisories matching 1.4.9 **23**advisories on older versions only **0**field reports on 1.4.9 ## What the status means Security status: **clear** · Forge verdict: not enough reports yet Clear: no published advisory (OSV) matched 1.4.9 and no field report flagged it, as of 5 Nov 2026. Clear means no known pattern or advisory matched, not that a tool is safe. Advisories are matched to one exact version. An advisory can only be matched once it is published, and field reports need 5 people, at least 2 verified, before a version gets a Forge Score ([methodology](https://theagentforge.io/methodology)). ## Published advisories (OSV) | Advisory | Kind | Matches 1.4.9 | Fixed in | Published | | --- | --- | --- | --- | --- | | [GHSA-8h5w-f6q9-wg35](https://osv.dev/vulnerability/GHSA-8h5w-f6q9-wg35) CVE-2023-32785, PYSEC-2026-372 | vulnerability | no | 0.0.247 | 2023-10-21 | | [GHSA-gr75-jv2w-4656](https://osv.dev/vulnerability/GHSA-gr75-jv2w-4656) CVE-2026-55443, PYSEC-2026-2192, PYSEC-2026-2556 | vulnerability | no | 1.3.9 | 2026-06-16 | | [GHSA-3644-q5cj-c5c7](https://osv.dev/vulnerability/GHSA-3644-q5cj-c5c7) CVE-2026-45134, PYSEC-2026-2555, PYSEC-2026-2560 | vulnerability | no | 0.3.30 | 2026-05-13 | | [GHSA-3hjh-jh2h-vrg6](https://osv.dev/vulnerability/GHSA-3hjh-jh2h-vrg6) CVE-2024-2965, PYSEC-2024-118, PYSEC-2026-2561 | vulnerability | no | 0.2.5, 73c42306745b0831aa6fe7fe4eeb70d2c2d87a82 | 2024-06-06 | | [PYSEC-2024-323](https://osv.dev/vulnerability/PYSEC-2024-323) CVE-2024-5998, GHSA-f2jm-rw3h-6phg, PYSEC-2026-1514 | vulnerability | no | 0.2.9 | 2024-09-17 | | [GHSA-6h8p-4hx9-w66c](https://osv.dev/vulnerability/GHSA-6h8p-4hx9-w66c) CVE-2023-32786, PYSEC-2026-1508 | vulnerability | no | 0.0.329 | 2023-10-21 | | [GHSA-45pg-36p6-83v9](https://osv.dev/vulnerability/GHSA-45pg-36p6-83v9) CVE-2024-8309, PYSEC-2024-115, PYSEC-2026-1507 | vulnerability | no | 0.2.0 | 2024-10-29 | | [GHSA-rgp8-pm28-3759](https://osv.dev/vulnerability/GHSA-rgp8-pm28-3759) CVE-2024-3571, PYSEC-2026-1510 | vulnerability | no | 0.0.353 | 2024-04-16 | | [GHSA-h9j7-5xvc-qhg5](https://osv.dev/vulnerability/GHSA-h9j7-5xvc-qhg5) CVE-2024-0243, PYSEC-2024-235, PYSEC-2026-1509 | vulnerability | no | 0.1.0 | 2024-02-26 | | [GHSA-57fc-8q82-gfp3](https://osv.dev/vulnerability/GHSA-57fc-8q82-gfp3) CVE-2023-36188, PYSEC-2023-109 | vulnerability | no | 0.0.247 | 2023-07-06 | | [GHSA-7gfq-f96f-g85j](https://osv.dev/vulnerability/GHSA-7gfq-f96f-g85j) CVE-2023-36281, PYSEC-2023-151 | vulnerability | no | 0.0.312, 0.0.171 | 2023-08-22 | | [GHSA-prgp-w7vf-ch62](https://osv.dev/vulnerability/GHSA-prgp-w7vf-ch62) CVE-2023-39659, PYSEC-2023-147 | vulnerability | no | 0.0.325, 0.0.233 | 2023-08-15 | | [GHSA-92j5-3459-qgp4](https://osv.dev/vulnerability/GHSA-92j5-3459-qgp4) CVE-2023-38896, PYSEC-2023-146 | vulnerability | no | 0.0.236, 0.0.195 | 2023-08-15 | | [GHSA-fj32-q626-pjjc](https://osv.dev/vulnerability/GHSA-fj32-q626-pjjc) CVE-2023-38860, PYSEC-2023-145 | vulnerability | no | 0.0.247 | 2023-08-15 | | [GHSA-gwqq-6vq7-5j86](https://osv.dev/vulnerability/GHSA-gwqq-6vq7-5j86) CVE-2023-36095, PYSEC-2023-138 | vulnerability | no | 0.0.236 | 2023-08-05 | | [GHSA-2qmj-7962-cjq8](https://osv.dev/vulnerability/GHSA-2qmj-7962-cjq8) CVE-2023-36258, PYSEC-2023-98 | vulnerability | no | 0.0.247 | 2023-07-03 | | [GHSA-6643-h7h5-x9wh](https://osv.dev/vulnerability/GHSA-6643-h7h5-x9wh) CVE-2023-34541, PYSEC-2023-92 | vulnerability | no | 0.0.247 | 2023-06-20 | | [GHSA-x32c-59v5-h7fg](https://osv.dev/vulnerability/GHSA-x32c-59v5-h7fg) CVE-2023-34540, PYSEC-2023-91 | vulnerability | no | 0.0.225 | 2023-06-14 | | [GHSA-655w-fm8m-m478](https://osv.dev/vulnerability/GHSA-655w-fm8m-m478) CVE-2023-46229, PYSEC-2023-205 | vulnerability | no | 0.0.317, 9ecb7240a480720ec9d739b3877a52f76098a2b8 | 2023-10-19 | | [GHSA-fprp-p869-w6q2](https://osv.dev/vulnerability/GHSA-fprp-p869-w6q2) CVE-2023-29374, PYSEC-2023-18 | vulnerability | no | 0.0.132 | 2023-04-05 | | [GHSA-7q94-qpjr-xpgm](https://osv.dev/vulnerability/GHSA-7q94-qpjr-xpgm) CVE-2023-36189, PYSEC-2023-110 | vulnerability | no | 0.0.247 | 2023-07-06 | | [GHSA-f73w-4m7g-ch9x](https://osv.dev/vulnerability/GHSA-f73w-4m7g-ch9x) CVE-2023-39631, PYSEC-2023-162, PYSEC-2023-163 | vulnerability | no | 0.0.308 | 2023-09-01 | | [GHSA-h59x-p739-982c](https://osv.dev/vulnerability/GHSA-h59x-p739-982c) CVE-2024-28088, PYSEC-2024-43, PYSEC-2024-45 | vulnerability | no | 0.0.339, 0.1.11 | 2024-03-04 | Data from OSV (osv.dev), which serves the GitHub and PyPI advisory databases and the OpenSSF malicious-package records; checked 5 Nov 2026. ## Field reports on the Forge No field reports on 1.4.9 yet.
