Semi-Quantum Cryptography with Certified Deletion

Certified deletion allows a client to upload encrypted data to a server as a quantum state, then later request that the server delete their data and detect whether the server complies. If verification passes, then the data on the server will remain hidden even if the decryption key is later leake...

CVE-2026-84686

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...

EulerOS Virtualization 2.11.1 : libgcrypt (EulerOS-SA-2026-3428)

According to the versions of the libgcrypt packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : Libgcrypt before 1.12.2 sometimes allows a heap-based buffer overflow and denial of service via crafted ECDH ciphertext to...

CVE-2026-75803

A flaw in OpenSSL causes EVPCipher to skip AEAD tag verification for ChaCha20-Poly1305 and AES-OCB ciphers when decrypting empty ciphertexts. This allows remote attackers to submit forged messages that affected applications incorrectly accept as valid. Mitigation To mitigate this ensure that all...

Astra Linux – Vulnerability in Nettle

A flaw was discovered in the way Nettle’s RSA decryption functions handled specially crafted ciphertext. An attacker could exploit this flaw to deliver manipulated ciphertext, resulting in application crashes and denial of service...

CVE-2026-86189 WWBN AVideo Unauthenticated Path Traversal via notify.ffmpeg.json.php

WWBN AVideo contains a path traversal vulnerability in notify.ffmpeg.json.php that allows unauthenticated attackers to write files to arbitrary locations by supplying a caller-chosen path in the avideoRelativePath parameter. Attackers can replay any previously issued ciphertext as a notifyCode...

CVE-2026-84971 Persistent client crash loop via undersized FLE2 insert-update ciphertext in decryption path

Improper handling of an unexpected value size in the decryption path of a client-side encryption library can cause a failed internal check that terminates the process using the library. A party able to place a suitably formed encrypted value where an application will decrypt it, or able to contro...
