Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was found in quarkus-core. This vulnerability occurs because the TLS protocol configured with quarkus.http.ssl.protocols is not enforced, and the client can force the selection of the weaker supported TLS protocol.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

In Quarkus, the quarkus.http.ssl.protocols configuration intended to restrict TLS connections to specific protocol versions (e.g., TLS 1.2+) is not properly enforced. An attacker negotiating an SSL/TLS handshake can override server preferences and force the use of weaker supported protocols like TLS 1.0 or TLS 1.1, exposing connections to known cryptographic weaknesses in legacy protocols.

MitigationEnsure Quarkus is updated to a version where this issue is fixed. If immediate patching is not possible, implement additional controls at the load balancer or reverse proxy level to enforce strong TLS protocols and reject downgrade attempts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Quarkus version
    Review your project pom.xml for the quarkus-bom or quarkus-core version, or check the build artifacts/logs. Alternatively, query the Quarkus application at runtime for its version endpoint if available.
    Affected if The installed Quarkus version is below 2.13.8 (e.g., 2.13.7, 2.13.0, 2.12.x, etc.)
  2. Locate SSL/TLS configuration
    Search for 'quarkus.http.ssl' configuration in your application.properties or application.yaml file, or any external configuration source that Quarkus reads.
    Affected if SSL/TLS is enabled via quarkus.http.ssl.configuration with any protocol restrictions set via quarkus.http.ssl.protocols
  3. Check configured SSL protocols
    Inspect the quarkus.http.ssl.protocols value in your configuration. If not explicitly set, the default behavior allows protocol negotiation.
    Affected if quarkus.http.ssl.protocols is set but allows TLS 1.0 or TLS 1.1, or if the property is unset (default behavior accepts any supported protocol)

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to 2.13.8 or later
Fixed in 2.13.8
Interim mitigation

Ensure Quarkus is updated to a version where this issue is fixed. If immediate patching is not possible, implement additional controls at the load balancer or reverse proxy level to enforce strong TLS protocols and reject downgrade attempts.

Recommended fix High confidence

2.13.8 or later stable release

  1. Upgrade Quarkus to version 2.13.8 or later (e.g., 2.13.8.Final or later stable release)
  2. Verify the fix by testing that the TLS protocol configured via quarkus.http.ssl.protocols is properly enforced and cannot be downgraded by clients
  3. Ensure that server-side TLS configuration explicitly disables legacy protocols (TLS 1.0, TLS 1.1) if not already done
