Name of the Vulnerable Software and Affected Versions Social Media Share Buttons & Social Sharing Icons versions prior to 3.0.2 Description Insufficient input sanitization and output escaping allow unauthenticated attackers to perform Reflected Cross-Site Scripting XSS, a technique where maliciou...

CVE-2026-89047: Improper Neutralization of Input During Web Page Generation

The Social Media Share Buttons & Social Sharing Icons plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject...

Your car’s app could be telling Big Tech who you are and where you go

A study testing 21 cars from 19 brands and 30 companion apps found connections to advertising and tracking companies, and evidence that some apps shared sensitive personal data. Modern cars can unlock remotely, route around traffic, stream entertainment, summon roadside help, and cool or heat the...

Quantum Secret Sharing and Error Correction Vs No-Cloning

Secret sharing is ubiquitous throughout cryptography. All possible access structures are classically feasible, and in the case of threshold access structures, the protocols are even very efficient. However, when moving to the quantum setting, the no-cloning theorem shows that many access structur...

CVE-2026-101269 Incorrect session validation for API-uploaded files

The mechanism binding API-uploaded files to the uploader's authentication method is not working correctly and the same session token is used for all token-based API users. Since API-uploaded files are refered to by randomly generated UUIDs and only exist for a day, there is virtually no risk, but...

CVE-2026-87609

An use after free flaw was found in the Sharing component of the Chromium browser. Upstream bugs: https://issues.chromium.org/issues/547322272...

Does the Readout Bypass Leak the Input? A Feature-Visibility Audit of Hybrid Quantum-Classical Models

Readout-side residual hybrids concatenate raw inputs with measured quantum features. Under single-example gradient sharing, a biased first linear layer admits standard analytic recovery of its input, so the bypass exposes raw coordinates without requiring inversion of the quantum circuit. We audi...

Quantum Leakage Resilience of Shamir Secret Sharing

We initiate the study of quantum leakage resilience of unmodified Shamir secret sharing over prime fields. A well-studied leakage model for Shamir's secret sharing classically is single-bit local leakage from each share. We consider its quantum analogue where, for each party, a local leakage...

A Three-Party W-State Quantum Secret Sharing Protocol with X-Gate Encoding and Forbidden-Outcome Detection

We develop a new three-party quantum secret-sharing QSS protocol based on a three-qubit W state. This protocol encodes the secret-sequence bits using X gates and employs randomly selected Hadamard operations and measurement bases to generate information and security-test rounds. We evaluate the...

com.github.luben/zstd-jni: luben zstd-jni: Remote use-after-free vulnerability in dictionary sharing

A flaw was found in luben zstd-jni. This flaw involves a use-after-free vulnerability in the ZstdCompressCtx.loadDict function, which handles dictionary sharing. A remote attacker could exploit this by manipulating dictionary sharing operations, potentially leading to denial of service, informati...

CVE-2026-75973

Improper Authentication vulnerability in Apache Tomcat. When Jakarta Authentication was configured with SimpleAuthConfigProvider as the default provider and multiple web application used that provider, the realm for the first web application to authenticate a request would be used for all web...

Physalia: Redistribution-Resistant Content Protection for Decentralized Storage

In decentralized storage systems, access control is often implemented by encrypting the data before upload and sharing the decryption key with authorized parties. A leaked key, however, makes the data publicly accessible, which lowers the barrier to content piracy below that of traditional system...

CVE-2026-95697 MISP: Insufficient Authorization Allows Sharing Group Editors to Overwrite Organization Metadata

MISP contains an authorization flaw in the Organisation model's captureOrg method. When the $force parameter is set to true, the method unconditionally overwrites organization metadata fields without verifying that the invoking user holds sufficient privileges. A user with a sharing group SG edit...

CVE-2026-95671

In MISP, the CollectionsController add method enforced the sharing-group usability authorization check and element capture only when the HTTP request method was POST. However, the underlying CRUDComponent::add method persists data on both POST and PUT requests. As a result, an authenticated user...
