CVSS 6.1
CVE-2026-34240 WRITEUP HIGH
jose vulnerable to untrusted JWK header key acceptance during signature verification
JOSE is a Javascript Object Signing and Encryption (JOSE) library. Prior to version 0.3.5+1, a vulnerability in jose could allow an unauthenticated, remote attacker to forge valid JWS/JWT tokens by using a key embedded in the JOSE header (jwk). The vulnerability exists because key selection could treat header-provided jwk as a verification candidate even when that key was not present in the trusted key store. Since JOSE headers are untrusted input, an attacker could exploit this by creating a token payload, embedding an attacker-controlled public key in the header, and signing with the matching private key. Applications using affected versions for token verification are impacted. This issue has been patched in version 0.3.5+1. A workaround for this issue involves rejecting tokens where header jwk is present unless that jwk matches a key already present in the application's trusted key store.

CVE-2026-34363 WRITEUP MEDIUM
Parse Server: LiveQuery protected field leak via shared mutable state across concurrent subscribers
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.65 and 9.7.0-alpha.9, when multiple clients subscribe to the same class via LiveQuery, the event handlers process each subscriber concurrently using shared mutable objects. The sensitive data filter modifies these shared objects in-place, so when one subscriber's filter removes a protected field, subsequent subscribers may receive the already-filtered object. This can cause protected fields and authentication data to leak to clients that should not see them, or cause clients that should see the data to receive an incomplete object. Additionally, when an afterEvent Cloud Code trigger is registered, one subscriber's trigger modifications can leak to other subscribers through the same shared mutable state. Any Parse Server deployment using LiveQuery with protected fields or afterEvent triggers is affected when multiple clients subscribe to the same class. This issue has been patched in versions 8.6.65 and 9.7.0-alpha.9.
CVSS 5.3
CVE-2026-34373 WRITEUP HIGH
Parse Server: GraphQL API endpoint ignores CORS origin restriction
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.66 and 9.7.0-alpha.10, the GraphQL API endpoint does not respect the allowOrigin server option and unconditionally allows cross-origin requests from any website. This bypasses origin restrictions that operators configure to control which websites can interact with the Parse Server API. The REST API correctly enforces the configured allowOrigin restriction. This issue has been patched in versions 8.6.66 and 9.7.0-alpha.10.
CVSS 8.8
CVE-2026-34503 WRITEUP HIGH
OpenClaw < 2026.3.28 - Incomplete WebSocket Session Termination on Device Removal and Token Revocation
OpenClaw before 2026.3.28 fails to disconnect active WebSocket sessions when devices are removed or tokens are revoked. Attackers with revoked credentials can maintain unauthorized access through existing live sessions until forced reconnection.
CVSS 8.1
CVE-2026-34504 WRITEUP HIGH
OpenClaw < 2026.3.28 - Server-Side Request Forgery via Unguarded Image Download in fal Provider
OpenClaw before 2026.3.28 contains a server-side request forgery vulnerability in the fal provider image-generation-provider.ts component that allows attackers to fetch internal URLs. A malicious or compromised fal relay can exploit unguarded image download fetches to expose internal service metadata and responses through the image pipeline.
CVSS 8.3
CVE-2026-34532 WRITEUP CRITICAL
Parse Server: Cloud function validator bypass via prototype chain traversal
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.67 and 9.7.0-alpha.11, an attacker can bypass Cloud Function validator access controls by appending "prototype.constructor" to the function name in the URL. When a Cloud Function handler is declared using the function keyword and its validator is a plain object or arrow function, the trigger store traversal resolves the handler through its own prototype chain while the validator store fails to mirror this traversal, causing all access control enforcement to be skipped. This allows unauthenticated callers to invoke Cloud Functions that are meant to be protected by validators such as requireUser, requireMaster, or custom validation logic. This issue has been patched in versions 8.6.67 and 9.7.0-alpha.11.
CVSS 9.1
CVE-2026-34573 WRITEUP HIGH
Parse Server: GraphQL complexity validator exponential fragment traversal DoS
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.68 and 9.7.0-alpha.12, the GraphQL query complexity validator can be exploited to cause a denial-of-service by sending a crafted query with binary fan-out fragment spreads. A single unauthenticated request can block the Node.js event loop for seconds, denying service to all concurrent users. This only affects deployments that have enabled the requestComplexity.graphQLDepth or requestComplexity.graphQLFields configuration options. This issue has been patched in versions 8.6.68 and 9.7.0-alpha.12.
CVSS 7.5
CVE-2026-34574 WRITEUP MEDIUM
Parse Server: Session field immutability bypass via falsy-value guard
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.69 and 9.7.0-alpha.14, an authenticated user can bypass the immutability guard on session fields (expiresAt, createdWith) by sending a null value in a PUT request to the session update endpoint. This allows nullifying the session expiry, making the session valid indefinitely and bypassing configured session length policies. This issue has been patched in versions 8.6.69 and 9.7.0-alpha.14.
CVSS 5.4
CVE-2026-34595 WRITEUP MEDIUM
Parse Server: LiveQuery protected-field guard bypass via array-like logical operator value
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.70 and 9.7.0-alpha.18, an authenticated user with find class-level permission can bypass the protectedFields class-level permission setting on LiveQuery subscriptions. By sending a subscription with a $or, $and, or $nor operator value as a plain object with numeric keys and a length property (an "array-like" object) instead of an array, the protected-field guard is bypassed. The subscription event firing acts as a binary oracle, allowing the attacker to infer whether a protected field matches a given test value. This issue has been patched in versions 8.6.70 and 9.7.0-alpha.18.

A vulnerability was identified in TRENDnet TEW-713RE up to 1.02. The impacted element is an unknown function of the file /goform/setSysAdm. The manipulation of the argument admuser leads to command injection. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVSS 6.3
CVE-2026-32714 WRITEUP CRITICAL
SciTokens vulnerable to SQL Injection in KeyCache
SciTokens is a reference library for generating and using SciTokens. Prior to version 1.9.6, the KeyCache class in scitokens was vulnerable to SQL Injection because it used Python's str.format() to construct SQL queries with user-supplied data (such as issuer and key_id). This allowed an attacker to execute arbitrary SQL commands against the local SQLite database. This issue has been patched in version 1.9.6.
CVSS 9.8
CVE-2026-32716 WRITEUP HIGH
SciTokens: Authorization Bypass via Incorrect Scope Path Prefix Checking
SciTokens is a reference library for generating and using SciTokens. Prior to version 1.9.6, the Enforcer incorrectly validates scope paths by using a simple prefix match (startswith). This allows a token with access to a specific path (e.g., /john) to also access sibling paths that start with the same prefix (e.g., /johnathan, /johnny), which is an Authorization Bypass. This issue has been patched in version 1.9.6.
CVSS 8.1
CVE-2026-32727 WRITEUP HIGH
SciTokens: Authorization Bypass via Path Traversal in Scope Validation
SciTokens is a reference library for generating and using SciTokens. Prior to version 1.9.7, the Enforcer is vulnerable to a path traversal attack where an attacker can use dot-dot (..) in the scope claim of a token to escape the intended directory restriction. This occurs because the library normalizes both the authorized path (from the token) and the requested path (from the application) before comparing them using startswith. This issue has been patched in version 1.9.7.
CVSS 8.1
CVE-2026-34036 WRITEUP MEDIUM
Dolibarr Core Discloses Sensitive Data via Authenticated Local File Inclusion in selectobject.php
Dolibarr is an enterprise resource planning (ERP) and customer relationship management (CRM) software package. In versions 22.0.4 and prior, there is a Local File Inclusion (LFI) vulnerability in the core AJAX endpoint /core/ajax/selectobject.php. By manipulating the objectdesc parameter and exploiting a fail-open logic flaw in the core access control function restrictedArea(), an authenticated user with no specific privileges can read the contents of arbitrary non-PHP files on the server (such as .env, .htaccess, configuration backups, or logs…). At time of publication, there are no publicly available patches.
CVSS 6.5
CVE-2026-34041 WRITEUP CRITICAL
act: Unrestricted set-env and add-path command processing enables environment injection
act is a project which allows for local running of github actions. Prior to version 0.2.86, act unconditionally processes the deprecated ::set-env:: and ::add-path:: workflow commands, which was disabled due to environment injection risks. When a workflow step echoes untrusted data to stdout, an attacker can inject these commands to set arbitrary environment variables or modify the PATH for all subsequent steps in the job. This issue has been patched in version 0.2.86.
CVSS 9.8
CVE-2026-34042 WRITEUP HIGH
act: actions/cache server allows malicious cache injection
act is a project which allows for local running of github actions. Prior to version 0.2.86, act's built in actions/cache server listens to connections on all interfaces and allows anyone who can connect to it including someone anywhere on the internet to create caches with arbitrary keys and retrieve all existing caches. If they can predict which cache keys will be used by local actions, they can create malicious caches containing whatever files they please most likely allowing arbitrary remote code execution within the docker container. This issue has been patched in version 0.2.86.
