CVE-2026-71884

In Bouncy Castle for Java LTS before 2.73.13, the native one-shot CTR packet cipher did not check that the requested input length fitted the counter space the IV left. In CTR mode the IV and the block counter share one 16-byte block, so an IV of 13 to 15 bytes leaves a counter of only 1 to 3 byte...

CVE-2026-71884 Packet CTR reports a full success length after the counter is exhausted

In Bouncy Castle for Java LTS before 2.73.13, the native one-shot CTR packet cipher did not check that the requested input length fitted the counter space the IV left. In CTR mode the IV and the block counter share one 16-byte block, so an IV of 13 to 15 bytes leaves a counter of only 1 to 3 byte...

CVE-2026-71884

In Bouncy Castle for Java LTS versions before 2.73.13 , a vulnerability exists in the native one-shot CTR packet cipher . The component fails to verify if the requested input length fits the remaining counter space left by an IV of 13 to 15 bytes. This allows the counter to wrap, causing the keys...

CVE-2026-63567

Observable discrepancy in IesEngine.DecryptBlock in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote attacker who has captured an IES or ECIES ciphertext, and who can submit modified ciphertexts for decryption under the same key pair, to recover its plaintext via a CBC...

CVE-2026-63567 IesEngine block-cipher mode checks padding before MAC (CBC padding oracle)

Observable discrepancy in IesEngine.DecryptBlock in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote attacker who has captured an IES or ECIES ciphertext, and who can submit modified ciphertexts for decryption under the same key pair, to recover its plaintext via a CBC...

CVE-2026-63567

The bc-csharp library by Bouncy Castle Inc. is vulnerable in versions before 2.7.0 due to an observable discrepancy in IesEngine.DecryptBlock. In block-cipher mode, the engine decrypts the ciphertext and removes padding before verifying the MAC. This allows a remote attacker to perform a CBC padd...

The Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CIQ crlsa-20225311 advisory. libgcrypt: ElGamal implementation allows plaintext recovery CVE-2021-40528 Tenable has extracted the preceding description block directly from the CIQ security...

automation-controller: automation-controller-container: automation-controller: notification template password fields can be decrypted by a notification-template administrator by replaying encrypted values across subfields, exposing plaintext Slack, PagerDuty, Twilio, AWS SNS and Grafana credentials

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. Notification template password fields are encrypted with a key derived from the secret key, the object primary key, and the field name, but not the subfield name, and the API returns the full ciphertext of a passwor...

CVE-2026-84499 Automation-controller: automation-controller-container: automation-controller: write-only survey password recovered in plaintext via schedule/workflowjobtemplatenode survey min/max validation error message

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. Survey questions of type password are write-only and stored encrypted, displayed only as a placeholder on read. When a schedule or workflow job template node is revalidated against a tightened survey specification,...

CVE-2023-54356

A flaw was found in Kyverno. The software supports insecure 3DES cipher suites on its TLS endpoints. A remote attacker could exploit this vulnerability, known as the Sweet32 attack, to recover small amounts of plaintext data. This exploitation requires very long-lived TLS connections carrying lar...
