Summary
Bouncy Castle for Java bcpkix, bcprov, bcpkix-fips on All (API modules) allows Excessive Allocation
Allocation of Resources Without Limits or Throttling vulnerability in Legion of the Bouncy Castle Inc. Bouncy Castle for Java bcpkix, bcprov, bcpkix-fips on All (API modules) allows Excessive Allocation. This vulnerability is associated with program files https://github.Com/bcgit/bc-java/blob/main/pkix/src/main/java/org/bouncycastle/pkix/jcajce/PKIXCertP... https://github.Com/bcgit/bc-java/blob/main/pkix/src/main/java/org/bouncycastle/pkix/jcajce/PKIXCertPathReviewer.java , https://github.Com/bcgit/bc-java/blob/main/prov/src/main/java/org/bouncycastle/x509/PKIXCertPathRevi... https://github.Com/bcgit/bc-java/blob/main/prov/src/main/java/org/bouncycastle/x509/PKIXCertPathReviewer.java .
This issue affects Bouncy Castle for Java: from BC 1.44 through 1.78, from BCPKIX FIPS 1.0.0 through 1.0.7, from BCPKIX FIPS 2.0.0 through 2.0.7.
Impact
The application allocates resources such as memory, threads, or file descriptors based on untrusted input without enforcing a cap. Typical impact: resource exhaustion leading to denial of service.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-8916? CVE-2025-8916 is a medium-severity allocation of resources without limits or throttling vulnerability in org.bouncycastle:bcpkix-fips (maven), affecting versions >= 1.0.0, <= 1.0.7. It is fixed in 1.0.8, 2.0.8, 1.79. The application allocates resources such as memory, threads, or file descriptors based on untrusted input without enforcing a cap.
- Which packages are affected by CVE-2025-8916?
org.bouncycastle:bcpkix-fips(maven) (versions >= 1.0.0, <= 1.0.7)org.bouncycastle:bcpkix-jdk15on(maven) (versions >= 1.44, < 1.79)org.bouncycastle:bcpkix-jdk15to18(maven) (versions >= 1.44, < 1.79)org.bouncycastle:bcpkix-jdk18on(maven) (versions >= 1.44, < 1.79)
- Is there a fix for CVE-2025-8916? Yes. CVE-2025-8916 is fixed in 1.0.8, 2.0.8, 1.79. Upgrade to this version or later.
- Is CVE-2025-8916 exploitable, and should I be worried? Whether CVE-2025-8916 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-8916 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
