JLSEC-2026-626 Rsync versions before 3.4.3 contain a time-of-check to time-of-use (TOCTOU) race condition in daemon...

Rsync versions before 3.4.3 contain a time-of-check to time-of-use TOCTOU race condition in daemon file handling that allows attackers to redirect file writes outside intended directories by replacing parent directory components with symbolic links. Attackers with write access to a module path ca...

CVE-2026-49440 Deno: Miller-Rabin Primality Test Allows Zero Rounds

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.8.1, node:crypto.checkPrimecandidate, options, callback and crypto.checkPrimeSynccandidate, options ran no Miller-Rabin rounds at all when the caller left options.checks at its default of 0. In that mode, the only test applied ...

CVE-2026-54911

UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Prior to 5.13.0, ujson.dumps or ujson.dump or ujson.encode have a rejectbytes=False option. When set, they may accept malformed or truncated UTF-8 byte sequences, silently rewriting them into different...

CVE-2026-56213 Capgo - Unauthenticated Cross-Tenant Metrics Poisoning via upsert_version_meta RPC

Capgo before 12.128.2 contains an authorization bypass vulnerability in the public.upsertversionmeta SECURITY DEFINER function exposed via PostgREST RPC, allowing unauthenticated attackers to insert arbitrary rows into versionmeta for any appid. Attackers can exploit this by calling the RPC...

CVE-2026-48990

joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption JOSE standards. In versions 1.3.4 through 1.6.5, joserfc accepts oversized RFC7797 b64=false JWS payloads without applying JWSRegistry.maxpayloadlength, which can lead to resource exhaustion...

CVE-2026-48990 joserfc: b64=false RFC7797 JWS payloads bypass JWSRegistry payload-size limits during deserialization

joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption JOSE standards. In versions 1.3.4 through 1.6.5, joserfc accepts oversized RFC7797 b64=false JWS payloads without applying JWSRegistry.maxpayloadlength, which can lead to resource exhaustion...

Malwarebytes earns AV-TEST Top Product award, aces other third-party tests

Our job is to protect people from online threats, and independent testing is one of the best ways to measure how well we’re doing. Malwarebytes nabbed AV-TEST's Top Product award after scoring 17.5 points out of a possible 18 in the research organization's most recent Windows security test. The...

GHSA-VCC4-2C75-VC9V Caddy: stripHTML template function bypass

Summary Caddy’s stripHTML template function cannot reliably remove all HTML tags from input strings. Certain malformed HTML, such as img src=x onerror=alert, can bypass the tag-stripping logic, potentially leaving dangerous content in the output if it is later rendered as HTML. This may allow...

GHSA-9XG4-QHM4-G43W Deno: Miller-Rabin Primality Test Allows Zero Rounds

Summary node:crypto.checkPrimecandidate, options, callback and crypto.checkPrimeSynccandidate, options ran no Miller-Rabin rounds at all when the caller left options.checks at its default of 0. In that mode, the only test applied to the candidate was trial division by the primes up to 17,863. Any...

CVE-2026-53776

Perry before 0.5.1166 contains a JWT validation vulnerability that allows remote attackers to bypass token expiration by exploiting the unconditional setting of validateexp = false in the verifydecode helper within the stdlib JWT verification path. Attackers in possession of a previously issued...

Improper Error Handling

@hulumi/drift is vulnerable to Improper Error Handling. The vulnerability is due to the classifier failing open on adapter errors and incorrectly promoting mixed verdicts, which allows incorrect classification results and may enable unauthorized or unintended actions based on inaccurate trust...

Making secret scanning more trustworthy: Reducing false positives at scale

Secret scanning plays a critical role in protecting developers and organizations. It helps catch exposed credentials early and prevents small mistakes from turning into real incidents. At GitHub's scale, even small inefficiencies create real friction. Too many false positives make alerts harder t...

Improper Handling of Exceptional Conditions

Overview @hulumi/drift is a Local-first drift classifier and live posture validator — distinguishes provider-API churn from console break-glass from genuine IaC drift, then renders read-only live posture findings as JSON, Markdown, and SARIF. Verdict logic mirrors HulumiDrift.tla Ha Affected...

A Robust Framework for Sybil Attack Detection in Vehicular Ad Hoc Networks

Sybil attacks create an illusion of traffic congestion by utilizing fake identities, which undermines the reliable and safe operation of vehicular ad hoc networks VANETs. Existing detection mechanisms struggle to effectively handle Sybil attacks as they are i susceptible to high false positive...

Runtime Skill Audit: Targeted Runtime Probing for Agent Skill Security

Agent skills let LLM agents reuse instructions, resources, tools, and workflows, but they also create a new place for malicious behavior to hide. A skill may look benign in its documentation or code while becoming harmful only when it is invoked with particular user requests, local assets,...

Nuclei 3.9.0

Nuclei is a modern, high-performance vulnerability scanner that leverages simple YAML-based templates. It empowers you to design custom vulnerability detection scenarios that mimic real-world conditions, leading to zero false positives...
