CVE-2026-18040: Observable Timing Discrepancy

In Bouncy Castle for Java before 1.86, HQC leaked secret-derived data through two side channels: its GF2^8 arithmetic used lookup tables indexed by field elements, making the cache line touched a function of the operand, and its fixed-weight support sampler left its duplicate scan as soon as a...

CVE-2026-71892: Incorrect Comparison

In Bouncy Castle for Java before 1.86, the opt-in key-size validation on CMS key-transport recipients, org.bouncycastle.cms.jcajce.JceKeyTransRecipient.setKeySizeValidationtrue, never ran for a message using RFC 9709 content-encryption key derivation id-alg-cek-hkdf-sha256. The branch that should...

Linux Distros Unpatched Vulnerability : CVE-2026-18036

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In Bouncy Castle for Java before 1.86, NTRU reduced secret values with the % operator in three helpers whose reference implementations are deliberately...

Quantum Machine Learning Protection of Military Quantum Key Distribution against Cryptographically Camouflaged Attacks

Quantum key distribution proves its protocol secure and says nothing about the hardware beneath it, so military and government operators fielding it for command-and-control keys monitor the channel for implementation attacks, and that monitoring has a blind spot. An adversary with a kleptographic...

Headroom vulnerable to Cross-Site WebSocket Hijacking (CSWSH)

Summary The Headroom WebSocket server does not validate the Origin header of incoming client WebSocket requests before forwarding the request to the upstream server, allowing malicious WebSocket clients to perform arbitrary LLM requests without authentication. This can be exploited by a malicious...

CVE-2026-82042

UTMStack before 11.2.16 contains an authentication bypass vulnerability that allows remote attackers to gain full administrative API access by presenting a valid Utm-Internal-Key header matching the INTERNALKEY environment variable value, which the InternalApiKeyFilter accepts for any endpoint...

CVE-2026-82042

Versions of UTMStack before 11.2.16 are vulnerable to an authentication bypass in the InternalApiKeyFilter component. The vulnerability allows remote attackers to gain full administrative API access by providing a Utm-Internal-Key header that matches the INTERNAL_KEY environment variable. Because...

CVE-2026-23937

A flaw was found in Zabbix. Authenticated users can exploit the Zabbix API's host.get action to extract a host's Pre-Shared Key PSK. This could lead to a loss of data integrity, as the extracted key may enable unauthorized access or modification of sensitive information...

CVE-2026-18036

A flaw was found in Bouncy Castle. A timing side-channel vulnerability in the NTRU algorithm can lead to information disclosure. The implementation performs variable-time division operations on secret data instead of constant-time calculations, causing processing time to vary depending on the...
