Hi,
The following vulnerability was published for rekor.
CVE-2026-23831[0]:
| Rekor is a software supply chain transparency log. In versions 1.4.3
| and below, the entry implementation can panic on attacker-controlled
| input when canonicalizing a proposed entry with an empty
| spec.message, causing nil Pointer Dereference. Function validate()
| returns nil (success) when message is empty, leaving sign1Msg
| uninitialized, and Canonicalize() later dereferences
| v.sign1Msg.Payload. A malformed proposed entry of the cose/v0.0.1
| type 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. This issue has been fixed in version 1.5.0.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
