Threats affecting pkg:github/bcpg

CVE-2026-59640 is a high-severity vulnerability in Bouncy Castle for Java (BC-JAVA) involving an OpenPGP CFB quick-check oracle on symmetric/session-key paths. This affects versions before 1.85, versions from 2.73.0 up to but not including 2.73.12, and certain FIPS series versions. The vulnerability is categorized under CWE-203 (Observable Discrepancy). No official patch or remediation level has been confirmed yet.

CVE-2026-59643 is a high-severity vulnerability in Legion of the Bouncy Castle Inc.'s BC-JAVA library affecting versions 1.81 through before 1.85. The issue involves improper verification of cryptographic signatures, specifically OpenPGP inline-signature policy failures that are silently ignored. This flaw also impacts the Bouncy Castle for Java FIPS (BC-FJA) before version bcpg-fips 2.0.13. The vulnerability could allow attackers to bypass signature verification checks, undermining cryptographic assurances.

CVE-2026-59648 is a medium severity vulnerability in Bouncy Castle for Java (BC-JAVA) affecting versions before 1.85 and certain LTS and FIPS versions. The issue involves the OpenPGP Argon2 S2K implementation honoring attacker-chosen memory and iteration parameters without limits or throttling, which can lead to resource exhaustion. No official patch or remediation level has been confirmed yet.

CVE-2026-59649 is a high severity vulnerability in Bouncy Castle for Java (BC-JAVA) involving memory allocation with an excessive size value. Specifically, the OpenPGP user-attribute subpacket length is only bounded by the JVM's maximum memory, potentially leading to excessive memory allocation. This affects versions before 1.85, as well as certain 2.x LTS and FIPS series versions prior to specified patch releases.

Allocation of resources without limits or throttling, Uncontrolled Resource Consumption vulnerability in Legion of the Bouncy Castle Inc. BC-JAVA bcpg on all (pg modules). This vulnerability is associated with program files AEADEncDataPacket.Java, BcAEADUtil.Java, JceAEADUtil.Java, OperatorHelper.Java. This issue affects BC-JAVA: from 1.74 before 1.80.2, from 1.81 before 1.81.1, from 1.82 before 1.84.
