CVE-2026-24117
Summary
/api/v1/index/retrievesupports retrieving a public key via a user-provided URL, allowing attackers to trigger SSRF to arbitrary internal services.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.
Impact
Patches
Upgrade to v1.5.0. Note that this is a breaking change to the search API and fully disables lookups by URL. If you require this feature, please reach out and we can discuss alternatives.
Workarounds
Disable the search endpoint with
--enable_retrieve_api=false.CVE-2026-23831

A malformed proposed entry of the
cose/v0.0.1type can cause a panic on a thread within the Rekor process. The thread is recovered so the client receives a 500 error message and service still continues, so the availability impact of this is minimal.Patches
