Harbor vs Tyk: at a glance
What is Harbor?
Harbor 2.15 patches swap Redis for Valkey and tighten registry security.
Harbor is shipping 2.15.x patch candidates with security and dependency work. 2.15.2 replaced Redis with Valkey as the cache backend and moved to Go 1.26. 2.15.3 added a manifest upload size limit, blocked proxy-cache poisoning through robot-name prefixes and neutralised CSV formulas in scan exports. 2.15.4-rc1 relaxes two defaults that had caused regressions: webhooks can reach private networks and legacy signer pulls are allowed.
What is Tyk?
Tyk's release feed is CVE dependency bumps across three maintained lines.
Tyk is cutting release candidates on several maintained lines at once (5.8, 5.13, 5.15) and nearly all of them carry the same dependency bump for a batch of CVEs: kin-openapi, golang.org/x/crypto, thrift and the OTLP trace exporters. The one feature entry is the 5.16.0 alpha, where the gateway sends node metadata when it registers.

Harbor
5.0INFRA · APIS
Harbor 2.15 patches swap Redis for Valkey and tighten registry security.
◆ Current state
Harbor is shipping 2.15.x patch candidates with security and dependency work. 2.15.2 replaced Redis with Valkey as the cache backend and moved to Go 1.26. 2.15.3 added a manifest upload size limit, blocked proxy-cache poisoning through robot-name prefixes and neutralised CSV formulas in scan exports. 2.15.4-rc1 relaxes two defaults that had caused regressions: webhooks can reach private networks and legacy signer pulls are allowed.
◆ Where it's heading
The patch line is closing abuse paths in a registry many teams expose internally, while walking back defaults that broke existing setups. The Valkey switch shows Harbor following the wider move off Redis after its licence change.
◆ Prediction
Expect 2.15.4 to go final with the restored defaults and a refreshed Trivy; the entries don't show what the next minor release contains.
Tyk
5.0INFRA · APIS
Tyk's release feed is CVE dependency bumps across three maintained lines.
◆ Current state
Tyk is cutting release candidates on several maintained lines at once (5.8, 5.13, 5.15) and nearly all of them carry the same dependency bump for a batch of CVEs: kin-openapi, golang.org/x/crypto, thrift and the OTLP trace exporters. The one feature entry is the 5.16.0 alpha, where the gateway sends node metadata when it registers.
◆ Where it's heading
The work is supply-chain maintenance spread across a wide support window, with feature work happening on the 5.16 alpha line. Gateway registration metadata hints at better fleet visibility from the control plane, but one ticket is not enough to call a direction.
◆ Prediction
Expect the CVE bumps to go final across 5.13 and 5.15 and more 5.16 alphas; what 5.16 adds beyond gateway registration isn't visible yet.
