Summary *
csaf-crud 1.4.13 is a security and verification cut on top of 1.4.12. It remediates one bundled-dependency finding — h2 queued empty HTTP/2 DATA frames without limit (RUSTSEC-2026-0258 / GHSA-q83h-524g-xf6h) — which is reachable here because the product serves HTTP/2 through hyper on its TLS listener. It also fixes a query-decoding defect that turned an invalid percent-escape into a NUL byte, and lands a large body of verification infrastructure: four fuzzing engines driven from one shared body, and four benchmark harnesses. This announcement carries 0.0 / NONE because an announcement is not itself a vulnerability -- not because nothing was fixed.

CVE ID
Vulnerability Title
Vulnerability Description
This advisory announces the 1.4.13 cut of csaf-crud. The security content is covered by the upstream advisory and is not re-scored here. The operator-visible changes are: h2 advances 0.4.15 -> 0.4.16, closing RUSTSEC-2026-0258; and an invalid percent-escape in a query string no longer decodes to a NUL byte but is left as the literal text it was, so a malformed query can no longer smuggle an interior NUL into a value that is later used as a key or a path component. Operators upgrading from 1.4.12 should treat the h2 fix as the reason to move: it affects the network-reachable HTTP/2 listener and has no configuration-level workaround within the product. The remainder of the release is testing infrastructure, which changes no runtime behaviour.
