{"cve":"CVE-2026-24117","nvd":{"published":"2026-01-22T22:16:21.577","modified":"2026-06-17T10:22:39.507","status":"Analyzed","description":"Rekor is a software supply chain transparency log. In versions 1.4.3 and below, attackers can trigger SSRF to arbitrary internal services because /api/v1/index/retrieve supports retrieving a public key via user-provided URL. Since the SSRF only can trigger GET requests, the request cannot mutate state. The response from the GET request is not returned to the caller so data exfiltration is not possible. A malicious actor could attempt to probe an internal network through Blind SSRF. The issue has been fixed in version 1.5.0. To workaround this issue, disable the search endpoint with --enable_retrieve_api=false.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-918"],"references":["https://github.com/sigstore/rekor/commit/60ef2bceba192c5bf9327d003bceea8bf1f8275f","https://github.com/sigstore/rekor/releases/tag/v1.5.0","https://github.com/sigstore/rekor/security/advisories/GHSA-4c4x-jm2x-pf9j"],"products":["linuxfoundation:rekor"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-24117","score":0.00363,"percentile":0.30187,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4c4x-jm2x-pf9j","url":"https://osv.dev/vulnerability/GHSA-4c4x-jm2x-pf9j","summary":"Rekor affected by Server-Side Request Forgery (SSRF) via provided public key URL","modified":"2026-09-10T03:50:58.946363595Z","packages":[{"ecosystem":"Go","name":"github.com/sigstore/rekor","purl":"pkg:golang/github.com/sigstore/rekor","ranges":["<1.5.0"],"fixed":["1.5.0"]}]},{"id":"GO-2026-4355","url":"https://osv.dev/vulnerability/GO-2026-4355","summary":"Rekor affected by Server-Side Request Forgery (SSRF) via provided public key URL in github.com/sigstore/rekor","modified":"2026-02-04T03:21:00.459703Z","packages":[{"ecosystem":"Go","name":"github.com/sigstore/rekor","purl":"pkg:golang/github.com/sigstore/rekor","ranges":["<1.5.0"],"fixed":["1.5.0"]}]}],"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).
