Description
A flaw was found in Quarkus REST that allows request parameters to leak between concurrent requests if endpoints use field injection without a CDI scope. This vulnerability allows attackers to manipulate request data, impersonate users, or access sensitive information.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.quarkus:quarkus-rest, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update io.quarkus:quarkus-rest to 3.18.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-1247 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.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This vulnerability marked as important severity rather than moderate because it leads to cross-request data leakage, which can compromise the confidentiality and integrity of user interactions. In a concurrent environment, multiple requests being served by a single, shared instance of an endpoint class means that…
