Bouncy Castle for Java Uncontrolled Resource Consumption Vulnerability

CVE-2025-9092GHSA-v6cf-mv9h-c8mc

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.bouncycastle:bc-fips 2.1.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2025-9092

Advisory: Bouncy Castle for Java Uncontrolled Resource Consumption Vulnerability
IDs: CVE-2025-9092, GHSA-v6cf-mv9h-c8mc
Record: https://patchnext.com/advisories/cve-2025-9092 (revision 1, source checked 26 Oct 2026, 16:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 1.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.bouncycastle:bc-fips 2.1.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.bouncycastle:bc-fips: affected >= 2.1.0, <= 2.1.0; fixed in 2.1.1

## Suggested inspection (read-only)
- Maven org.bouncycastle:bc-fips: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.bouncycastle:bc-fips.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-v6cf-mv9h-c8mc (GitHub-reviewed advisory GHSA-v6cf-mv9h-c8mc lists affected ranges: Maven org.bouncycastle:bc-fips >=2.1.0 <=2.1.0)

Commands are suggestions: review each one before running it.
