Impact

CVE-2026-13506 (GHSA-qp49-qgx5-5m26) is a Bouncy Castle flaw where forcing a lazily-parsed ASN.1 sequence resets its nesting-depth guard, allowing uncontrolled recursion, fixed in bcprov-jdk18on 1.85. The bundled jruby-openssl gem resolves its four Bouncy Castle jars through a single hardcoded version constant rather than a filesystem scan, so the vulnerable jar can't be swapped in place without also patching that constant and its three sibling jars — a coordinated update only a newer jruby-openssl release (0.16.2+) currently carries.
