CVE-2026-71892

Bouncy Castle for Java versions before 1.86 contain a flaw where opt-in key-size validation on CMS key-transport recipients fails for messages using RFC 9709 content-encryption key derivation (id-alg-cek-hkdf-sha256 ). The root cause is an incorrect comparison between a byte array and an ASN1Obje...

CVE-2026-17508

The Bouncy Castle for Java cryptographic library (versions before 1.86 , LTS before 2.73.13 , and FIPS before bcpkix-fips 1.0.13, 2.0.13, and 2.1.13) contains a vulnerability where password-based key derivation functions (KDFs) use unbounded cost parameters from untrusted input. Specifically, the...

EUVD-2026-91236

In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being processed, without bounding them, so a small input could dictate an arbitrary amount of work before any password or integrity check could...

Security Bulletin: IBM webMethods Integration Sever is affected by multiple CVEs related to Bouncy Castle for Java FIPS jars

Summary IBM webMethods Integration Sever uses third party Bouncy Castle for Java FIPS jars that are affected by multiple CVEs. Vulnerability Details CVEID:CVE-2026-13505 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...

CVE-2026-13505

A flaw was found in Bouncy Castle for Java FIPS BC-FJA. Sensitive cryptographic key material, intended to be securely erased from memory zeroised upon garbage collection, may persist longer than expected. This occurs because the zeroisation process relies on a deprecated Java finalization...
