Description
A critical vulnerability was reported in the versions of golang that Crossplane depends on. Details of the golang vulnerability are included below. Crossplane does not directly use the vulnerable functions from the net/netip package, but the version of golang libraries, runtime, and build tools have still been updated as part of this security advisory nonetheless.
Critical Vulnerabilities
Vulnerability: CVE-2024-24790, golang: net/netip: Unexpected behavior from Is methods for IPv4-mapped IPv6 addresses
Description: The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6 addresses, returning false for addresses which would return true in their traditional IPv4 forms.
Affected versions: 1.17.1,1.16.2,1.15.5
See screenshot for more details
Fixed versions: 1.17.2,1.16.3,1.15.6

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/crossplane/crossplane. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/crossplane/crossplane to 1.15.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7h65-4p22-39j6 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-7h65-4p22-39j6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-7h65-4p22-39j6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-7h65-4p22-39j6 in your dependencies?
O3 detects GHSA-7h65-4p22-39j6 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
