CVE-2025-8916 is a medium-severity vulnerability affecting the Legion of the Bouncy Castle Inc. BC Java libraries. It involves the allocation of resources without limits or throttling, potentially leading to excessive resource consumption. With a CVSS score of 6.3, this vulnerability poses a moderate risk to organizations utilizing the affected libraries. The issue is especially relevant for those deploying applications that rely on these cryptographic APIs.
The vulnerability affects multiple components: BC Java bcpkix and bcprov on all API modules, as well as BCPKIX FIPS bcpkix-fips across all API modules. Given its nature, organizations using these libraries should be vigilant, as the potential for resource exhaustion may lead to service degradation.
The vulnerability was published on August 13, 2025, and is classified under CWE-770. As of now, there are no known exploits in the wild, but organizations should prioritize remediation given the potential impact.
Organizations should address this vulnerability in their patch cycle to mitigate risks associated with excessive resource allocation.
Vulnerability Details
The vulnerability allows excessive allocation of resources in Legion of the Bouncy Castle Inc. BC Java libraries, specifically in the bcpkix and bcprov components, as well as in BCPKIX FIPS. The affected versions span from 1.44 to 1.78 for BC Java and from 1.0.0 to 2.0.7 for BCPKIX FIPS.
The CVSS score of 6.3 indicates a medium severity level, which requires organizations to take this vulnerability seriously. The attack vector is classified as NETWORK, and the attack complexity is low, meaning that an attacker may exploit this vulnerability without significant obstacles.
Technical Analysis
The root cause of this vulnerability lies in the inadequate management of resource allocation within the affected libraries. Resources are allocated without appropriate limits or throttling mechanisms, allowing for excessive consumption, which can lead to denial of service conditions.
The attack vector is network-based, and the complexity is low. No privileges are required for exploitation, and user interaction is not necessary. The impact on availability is low, but organizations should be aware of the potential for resource exhaustion.
Risk & Impact Analysis
Risk to organizations includes potential denial of service due to excessive resource allocation. This vulnerability could allow an attacker to exhaust resources, leading to degraded performance or service outages. The impact of such an incident can be significant, especially for organizations relying on the availability of these cryptographic services.
Given the CVSS score of 6.3, organizations should address this vulnerability in their patch cycle. The urgency is categorized as moderate, and organizations should schedule remediation as part of their security maintenance practices.
