CVE-2026-59648: CWE-770 Allocation of Resources Without Limits or Throttling in Legion of the Bouncy Castle Inc. BC-JAVA
CVE-2026-59648 is a medium severity vulnerability in Bouncy Castle for Java (BC-JAVA) affecting versions before 1.85 and certain LTS and FIPS versions. The issue involves the OpenPGP Argon2 S2K implementation honoring attacker-chosen memory and iteration parameters without limits or throttling, which can lead to resource exhaustion. No official patch or remediation level has been confirmed yet.
AI Analysis
Technical Summary
This vulnerability (CWE-770) in BC-JAVA occurs because the OpenPGP Argon2 S2K function accepts memory and pass parameters specified by an attacker without imposing limits or throttling. This can cause excessive resource consumption during cryptographic operations. The affected versions include BC-JAVA before 1.85, LTS versions before 2.73.12, and BC-FJA FIPS versions before 1.0.13, 2.0.13, and 2.1.13. The CVSS 4.0 base score is 6.9, indicating a medium severity. There is no vendor advisory or patch information available to confirm remediation status.
Potential Impact
An attacker can specify resource-intensive parameters for Argon2 S2K, potentially causing denial of service by exhausting memory or CPU resources on the affected system. There is no indication of privilege escalation or data compromise from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting resource usage at the application or system level if possible, but no official mitigation is documented.
