CVE-2026-58062 Details
Description
In Bouncy Castle for Java before 1.85, Stapled OCSP response accepted without binding to the checked certificate. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bc-fips 2.0.2 (2.0.X series) and 2.1.3 (2.1.X series).
A vulnerability exists in Bouncy Castle for Java in versions prior to 1.85, all LTS versions prior to 2.73.12, and in the FIPS versions 2.0.X prior to 2.0.2 and 2.1.X prior to 2.1.3. This vulnerability allows stapled OCSP responses to be accepted without proper binding to the certificate being checked. As a result, a response indicating a certificate is 'good' could be incorrectly applied to a different certificate, potentially leading to improper validation outcomes.
Users can upgrade to Bouncy Castle for Java version 1.85 or later, or to the LTS version 2.73.12 or later. For Bouncy Castle FIPS users, version 2.0.2 (2.0.X series) or 2.1.3 (2.1.X series) should be used.
