Crossplane v2.3.3 patches a TOCTOU security flaw in OCI package signature verification (GHSA-mf7q-r4rv-jv94) and fixes a namespace injection bug in `crossplane render`. Routine CVE bumps for Go deps included.

• securityUpgrade immediately to fix OCI signature TOCTOU (GHSA-mf7q-r4rv-jv94)

  The TOCTOU flaw means a compromised or malicious OCI registry could serve unsigned package content after passing signature verification. Any Crossplane deployment that installs packages from OCI registries is exposed. Upgrade to v2.3.3 — this fix lives in crossplane-runtime and is bundled in this release. Review the crossplane-runtime v2.3.3 advisory for full technical details and assess whether any packages installed on affected versions should be reinstalled.

• securitygolang.org/x/net and x/sys CVE patches — rebuild or upgrade

  The apis module now pulls updated golang.org/x/net and golang.org/x/sys. If you build Crossplane from source or vendor these deps in your own providers/functions, update your dependency pins to pick up the same CVE fixes. Pre-built images in v2.3.3 already include the patched versions.

• breakingcrossplane render namespace behavior changed for namespaced XRs

  If you use `crossplane render` in CI pipelines or local testing with namespaced XRs, the injected resource refs no longer carry a namespace. This matches real reconciler behavior and fixes breakage with strict-schema functions (e.g., KCL-generated bindings). Re-run your render tests after upgrading to confirm output changes don't mask real issues in your composition logic.
