As of 5 Nov 2026, the latest release of fastify on npm is 5.12.8. No published advisory (OSV) matches 5.12.8; 17 more affect older versions only. No field reports on 5.12.8 yet. Security status: clear. npm:fastify **5.12.8**latest on npm **0**advisories matching 5.12.8 **17**advisories on older versions only **0**field reports on 5.12.8 ## What the status means Security status: **clear** · Forge verdict: not enough reports yet Clear: no published advisory (OSV) matched 5.12.8 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 5.12.8 | Fixed in | Published | | --- | --- | --- | --- | --- | | [GHSA-389g-gv7q-r4x8](https://osv.dev/vulnerability/GHSA-389g-gv7q-r4x8) CVE-2026-107832 | vulnerability | no | 5.12.6 | 2026-10-22 | | [GHSA-4mh8-r7rc-xpvc](https://osv.dev/vulnerability/GHSA-4mh8-r7rc-xpvc) CVE-2026-92081 | vulnerability | no | 5.12.5 | 2026-09-30 | | [GHSA-9q9j-q6p8-xq58](https://osv.dev/vulnerability/GHSA-9q9j-q6p8-xq58) CVE-2026-84428 | vulnerability | no | 5.12.2 | 2026-09-30 | | [GHSA-p68q-wchp-6fh7](https://osv.dev/vulnerability/GHSA-p68q-wchp-6fh7) CVE-2026-76169 | vulnerability | no | 5.12.2 | 2026-09-30 | | [GHSA-hwr6-493r-vm6h](https://osv.dev/vulnerability/GHSA-hwr6-493r-vm6h) CVE-2026-84469 | vulnerability | no | 5.12.2 | 2026-09-30 | | [GHSA-667r-xxjv-c9mm](https://osv.dev/vulnerability/GHSA-667r-xxjv-c9mm) CVE-2026-84504 | vulnerability | no | 5.12.2 | 2026-09-30 | | [GHSA-w2qp-rph6-63g4](https://osv.dev/vulnerability/GHSA-w2qp-rph6-63g4) CVE-2026-18504 | vulnerability | no | 5.12.1 | 2026-09-02 | | [GHSA-3m5p-2c4r-xxw2](https://osv.dev/vulnerability/GHSA-3m5p-2c4r-xxw2) CVE-2026-16732 | vulnerability | no | 5.12.1 | 2026-09-02 | | [GHSA-573f-x89g-hqp9](https://osv.dev/vulnerability/GHSA-573f-x89g-hqp9) CVE-2026-3419 | vulnerability | no | 5.8.1 | 2026-03-05 | | [GHSA-247c-9743-5963](https://osv.dev/vulnerability/GHSA-247c-9743-5963) CVE-2025-32442, CVE-2026-33806, GHSA-mg2h-6x62-wpwc | vulnerability | no | 5.8.5, 5.3.2, 4.29.1 | 2026-04-15 | | [GHSA-444r-cwp2-x5xf](https://osv.dev/vulnerability/GHSA-444r-cwp2-x5xf) CVE-2026-3635 | vulnerability | no | 5.8.3 | 2026-03-25 | | [GHSA-mrq3-vjjr-p77c](https://osv.dev/vulnerability/GHSA-mrq3-vjjr-p77c) CVE-2026-25224 | vulnerability | no | 5.7.3 | 2026-02-02 | | [GHSA-jx2c-rxcm-jvmq](https://osv.dev/vulnerability/GHSA-jx2c-rxcm-jvmq) CVE-2026-25223 | vulnerability | no | 5.7.2 | 2026-02-02 | | [GHSA-3fjj-p79j-c9hh](https://osv.dev/vulnerability/GHSA-3fjj-p79j-c9hh) CVE-2022-41919 | vulnerability | no | 4.10.2, 3.29.4 | 2022-11-21 | | [GHSA-455w-c45v-86rg](https://osv.dev/vulnerability/GHSA-455w-c45v-86rg) CVE-2022-39288 | vulnerability | no | 4.8.1 | 2022-10-11 | | [GHSA-xw5p-hw6r-2j98](https://osv.dev/vulnerability/GHSA-xw5p-hw6r-2j98) CVE-2020-8192 | vulnerability | no | 2.15.1 | 2020-08-05 | | [GHSA-mq6c-fh97-4gwv](https://osv.dev/vulnerability/GHSA-mq6c-fh97-4gwv) CVE-2018-3711 | vulnerability | no | 0.38.0 | 2018-07-18 | 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 5.12.8 yet.
