{"cve":"CVE-2024-39687","nvd":{"published":"2024-07-05T18:15:32.663","modified":"2026-06-17T07:42:28.413","status":"Deferred","description":"Fedify is a TypeScript library for building federated server apps powered by ActivityPub and other standards. At present, when Fedify needs to retrieve an object or activity from a remote activitypub server, it makes a HTTP request to the `@id` or other resources present within the activity it has received from the web. This activity could reference an `@id` that points to an internal IP address, allowing an attacker to send request to resources internal to the fedify server's network. This applies to not just resolution of documents containing activities or objects, but also to media URLs as well. Specifically this is a Server Side Request Forgery attack. Users should upgrade to Fedify version 0.9.2, 0.10.1, or 0.11.1 to receive a patch for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:L","score":7.2},"cwes":["CWE-918"],"references":["https://github.com/dahlia/fedify/commit/30f9cf4a175704a04c874f3ea88414c5f1e00b28","https://github.com/dahlia/fedify/commit/c641e976089dd913f649889c1bfb016df04e86ba","https://github.com/dahlia/fedify/security/advisories/GHSA-p9cg-vqcc-grcx","https://github.com/dahlia/fedify/commit/30f9cf4a175704a04c874f3ea88414c5f1e00b28","https://github.com/dahlia/fedify/commit/c641e976089dd913f649889c1bfb016df04e86ba"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-39687","score":0.006,"percentile":0.48727,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p9cg-vqcc-grcx","url":"https://osv.dev/vulnerability/GHSA-p9cg-vqcc-grcx","summary":"Server Side Request Forgery (SSRF) attack in Fedify","modified":"2026-09-10T03:50:16.807434010Z","packages":[{"ecosystem":"npm","name":"@fedify/fedify","purl":"pkg:npm/%40fedify/fedify","ranges":["<0.9.2"],"fixed":["0.9.2"]},{"ecosystem":"npm","name":"@fedify/fedify","purl":"pkg:npm/%40fedify/fedify","ranges":[">=0.10.0 <0.10.2"],"fixed":["0.10.2"]},{"ecosystem":"npm","name":"@fedify/fedify","purl":"pkg:npm/%40fedify/fedify","ranges":[">=0.11.0 <0.11.2"],"fixed":["0.11.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
