CVE-2026-23831 is a medium severity vulnerability in sigstore's Rekor component (versions prior to 1.5.0) involving a NULL pointer dereference triggered by attacker-controlled input. Specifically, when a proposed entry with an empty spec.message is processed, the validate() function incorrectly returns success without initializing sign1Msg, leading to a panic in Canonicalize() when it dereferences the uninitialized pointer. This causes a thread panic resulting in a 500 error response to clients but does not crash the entire service, thus limiting availability impact. No confidentiality or integrity impact is observed. The vulnerability requires no authentication or user interaction and can be triggered remotely via crafted input. The issue has been fixed in version 1.5.
