Description
HAX open-apis provides microservice apis for HAX webcomponents repo that are shared infrastructure calls. An unauthenticated information disclosure vulnerability exists in the Penn State University deployment of the HAX content management system via the haxPsuUsage API endpoint, related to a flat present in open-apis versions up to and including 10.0.2. This allows any remote unauthenticated user to retrieve a full list of PSU websites hosted on HAX CMS. When chained with other authorization issues (e.g., HAX-3), this could assist in targeted attacks such as unauthorized content modification or deletion. Commit 06c2e1fbb7131a8fe66aa0600f38dcacae6b7ac7 patches the vulnerability.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @haxtheweb/open-apis. 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.
Remediation status
No patched version of @haxtheweb/open-apis has shipped for CVE-2025-48996 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 CVE-2025-48996 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 CVE-2025-48996. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
