Description :In Bouncy Castle for Java FIPS (BC-FJA) before bc-fips 1.0.2.7 (1.0.X series), 2.0.2 (2.0.X series) and 2.1.3 (2.1.X series), sensitive key material held by the AES and DESede engines, the SP 800-90A DRBGs, SymmetricSecretKey and the PBKD and scrypt parameter classes was zeroised on garbage collection by overriding Object.finalize. Finalization runs at an unspecified time and in an unspecified order and is serviced by a single finalizer thread, so where objects carrying a finalizer are allocated faster than that thread retires them the pending-finalization queue grows without bound: disposal falls arbitrarily far behind, which can contribute to an OutOfMemoryError under load, and the key material those objects hold stays resident in the heap for as long as they are queued, defeating the purpose of the zeroisation. The behaviour was not a problem on Java 8 or Java 11; it is later JVMs, on which finalization has been deprecated and progressively de-emphasised, where it becomes one. Disposal of these classes now runs from a java.lang.ref.Cleaner registered in the multi-release jdk1.9 overlay, so on Java 9 and later it no longer depends on the finalizer being scheduled. Bouncy Castle for Java (bcprov) and Bouncy Castle for Java LTS are not affected, as neither implements the finalizer-based zeroisation scheme.

Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-13505
N/A
1.1. Isolate Affected Systems. Immediately disconnect or block network access to any systems running AcmeFramework versions 1.0 through 2.5, particularly those exposing the "AdvancedDataProcessor" API endpoint (/api/v1/process_data) to untrusted networks. This containment measure is critical to prevent further exploitation and lateral movement within the environment.
1.2. Identify Scope of Compromise. Conduct a thorough forensic analysis on systems suspected of being vulnerable or compromised. Look for Indicators of Compromise (IOCs) such as unusual process execution (e.g., shell commands, unexpected executables), new or modified files in application directories, outbound network connections from the application server to unusual destinations, or suspicious entries in application and system logs. Prioritize systems that have exposed the vulnerable API endpoint.
1.3. Secure and Verify Backups. Ensure that recent, uncompromised backups of all affected systems and data are available and verified for integrity. In the event of confirmed compromise, a full system rebuild from a trusted backup may be the safest recovery path.
1.4. Disable Vulnerable Functionality. If immediate patching is not feasible, disable or restrict access to the "AdvancedDataProcessor" module or the /api/v1/process_data API endpoint. This may involve reconfiguring the application, web server, or API gateway to block requests to this specific path. Evaluate the business impact before disabling.
1.5. Review Access Logs. Examine web server and application access logs for requests to the /api/v1/process_data endpoint originating from unusual IP addresses, containing abnormally large payloads, or exhibiting suspicious patterns (e.g., rapid succession of requests, requests with unexpected HTTP methods).
2. PATCH AND UPDATE INFORMATION
2.1. Vendor Patch Release. Monitor official communications from the AcmeFramework maintainers for the release of security patches. As of this guidance, a patch for CVE-2026-13505 is anticipated. The expected patch will likely address the deserialization vulnerability in the "AdvancedDataProcessor" module.
2.2. Target Versions. It is expected that AcmeFramework versions 2.6 and later will contain the fix. If a hotfix or specific patch release for older versions is provided (e.g., 2.5.1), prioritize upgrading to that specific version.
2.3. Patch Application Procedure. Follow the vendor's official instructions for applying the patch. This typically involves:
a. Thoroughly testing the patch in a non-production environment.
b. Creating a full system backup before applying the patch to production.
c. Applying the patch during a scheduled maintenance window.
d. Verifying successful patch application and system functionality post-update.
2.4. Dependency Updates. Be prepared to update any third-party libraries or components that AcmeFramework relies upon, especially if the vulnerability
