| CVE-2026-0636 | 5.5 medium | 1.0% | no CPE yet | Improper neutralization of special elements used in an LDAP query ('LDAP injection') vulnerability in Legion of the Bouncy Castle Inc. BC-JAVA bcprov on all (prov modules). This vulnerability is associated with program files LDAPStoreHelper.

| CVE-2026-59644 | 8.7 high | 0.00% | bouncycastle, bc-java | In Bouncy Castle for Java before 1.85, MLS hash-ratchet honours arbitrary 32-bit generation counter from sender. | Fri 23 Oct |
| CVE-2026-12852 | 8.7 high | 0.00% | bouncycastle, bc-java | In Bouncy Castle for Java before 1.85, MLS wire decoder allocates attacker-declared opaque length before bounds check. | Fri 23 Oct |
| CVE-2026-17507 | 8.7 high | 0.00% | bouncycastle, bc-java | In Bouncy Castle for Java before 1.86, the MLS implementation (org.bouncycastle.mls) holds RFC 9420's uint32 leaf_index in a signed int, so a wire value with the top bit set decodes to a negative number. That is a legitimate encoding rather than malformed input, and it must still decode, since the MLS interop test vectors round-trip the full range. GroupKeySet.SecretTree.hasLeaf and Group.validateRemove compared the decoded value directly against the tree's leaf count, and a signed comparison treats any negative int as less than a positive bound, so an out-of-range sender passed the membership check. In the hasLeaf case the SenderData of an unprotected PrivateMessage could then drive LeafIndex.directPath through NodeIndex.parent() arithmetic that never reaches the tree root, growing the resulting node list without bound until the JVM exhausted its heap. A single small message from any current group member could therefore deny service to every other member of the group. Both comparisons now interpret the value as unsigned via Integer.toUnsignedLong, rejecting an out-of-range sender however it was encoded; well-formed leaf indices are unaffected. | 14 Oct |
