CVE-2026-59652 Details
Description
In Bouncy Castle for Java before 1.85, LDAP filter injection in legacy jdk1.4 LDAPStoreHelper.
A vulnerability allowing LDAP filter injection has been identified in Bouncy Castle for Java versions prior to 1.85, specifically within the LDAPStoreHelper component for legacy JDK 1.4. This issue arises because the LDAPStoreHelper did not properly escape distinguished name (DN) values before adding them to an LDAP search filter. As a result, a certificate containing LDAP filter metacharacters could manipulate the search filter during certification path building or CRL lookups.
Users can upgrade to Bouncy Castle for Java version 1.85 or later, where this vulnerability has been addressed. Instructions for updating can be found in the Bouncy Castle documentation.
