Hi, The following vulnerability was published for rekor. CVE-2026-24117[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
