What it is: CVE-2025-9092 is a low-severity denial of service vulnerability in Legion of the Bouncy Castle Inc. Bouncy Castle for Java - BC-FJA 2.1.0, published on 16 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2025-9092 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.bouncycastle:bc-fips (Maven): affected from 2.1.0; fixed in 2.1.1
- org.bouncycastle:bc-fips (Maven): affected from 2.1.0; fixed in 2.1.1

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
