Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2026-28496
Critical

FOSSBilling prior to version 0.8.0 has a Server-Side Template Injection (SSTI) vulnerability in the template rendering system. Administrators can inject arbitrary Twig expressions, leading to information disclosure and remote code execution.

CVE-2026-27604
Critical

FOSSBilling versions 0.5.4 to 0.8.0 have an authorization bypass in API role handling, allowing unauthenticated access to privileged `/api/system/*` endpoints. Attackers can invoke admin API methods without valid credentials.

CVE-2026-56315
Critical

Picklescan before 1.0.4 fails to block at least seven Python standard library modules, allowing for remote code execution. Attackers can craft malicious pickle files importing these unblocked modules, bypassing picklescan's safety validation.

CVE-2026-56274
CriticalEPSS 84%

Flowise versions before 3.1.2 contain multiple OS command injection vulnerabilities in the Custom MCP Server feature due to incomplete command-flag validation and a regex bypass in local file access restrictions.

CVE-2026-44089
Critical

The Totolink EX1200L router is vulnerable to a buffer overflow in the login functionality at the cgi-bin/cstecgi.cgi endpoint. Exploiting this vulnerability could lead to program crashes and remote code execution.

CVE-2026-11374
CriticalEPSS 65%

In ManageEngine ADSelfService Plus, RecoveryManager Plus, M365 Manager Plus, and ADAudit Plus, SSO tickets generated to authenticate the session could be predicted by an unauthenticated user, leading to account takeover.

CVE-2026-9733
Critical

Mojolicious::Plugin::Web::Auth::OAuth2 versions through 0.17 for Perl have an insecure default state parameter. When no state generator is specified in the constructor, it defaults to using a SHA-1 hash of predictable sources, allowing CSRF attacks.

CVE-2026-12866
Critical

The vulnerability in the expr-eval library allows arbitrary JavaScript code execution via the toJSFunction() API. An attacker can supply crafted expressions that are compiled into native code using new Function(), bypassing the intended expression sandbox and executing arbitrary code within the application's context.

CVE-2026-48746
CriticalEPSS 64%

Vulnerability in vLLM versions 0.3.0 to 0.22.0 allows bypass of OpenAI API AuthenticationMiddleware. An attacker can use the API without providing the configured VLLM_API_KEY or --api-key.

CVE-2026-56348
Critical

n8n versions before 2.20.0 contain a credential exfiltration vulnerability in the POST /rest/dynamic-node-parameters/options endpoint that allows authenticated users to bypass Allowed HTTP Request Domains restrictions. Attackers with credential access can cause the n8n server to issue HTTP requests with credentials to unauthorized hosts.

CVE-2026-48509
Critical

MessagePack for C# prior to versions 2.5.301 and 3.1.7 uses default serialization options that can lead to denial-of-service attacks. The default MessagePackInputFormatter() constructor is insecure as it may expose applications to hash-collision attacks against dictionary-like model properties.

CVE-2026-49468
Critical

LiteLLM proxy before version 1.84.0 has a Host-header parsing flaw that, under specific conditions, allows unauthenticated access to protected management routes. The issue arises from a mismatch between the route evaluated by the auth layer and the route actually dispatched by FastAPI.

CVE-2026-45034
Critical

PhpSpreadsheet prior to version 1.30.5 contained a vulnerability that allowed bypassing stream wrapper security checks, potentially leading to remote code execution (RCE). The issue stemmed from improper URL scheme validation, enabling attackers to exploit wrappers like phar://.

CVE-2026-12249
Critical

An issue was discovered in Canonical ADSys versions up to v0.16.2, involving the use of an unencrypted HTTP connection to request the CA certificate from the AD CS server. An attacker can perform a Man-in-the-Middle attack, leading to the installation of a malicious certificate in the system's local trust store.

CVE-2026-10789
Critical

A maliciously crafted webpage, when visited by a user with Autodesk Fusion Desktop running and the MCP extension enabled, can trigger a vulnerability in the MCP extension that could allow arbitrary code execution.

CVE-2026-7664
Critical

IBM Langflow OSS versions 1.0.0 through 1.8.4 contain a vulnerability due to improper authorization enforcement in the Streamable MCP transport endpoint. This allows unauthenticated attackers to access protected MCP project resources and execute MCP operations.

CVE-2026-12628
Critical

IBM Storage Protect Client 8.1.0.0 through 8.2.1.0 and IBM Storage Protect Snapshot For Windows 8.1.0.0 through 8.2.1.0 contain a hardcoded credential in the FlashCopy Manager (FCM) authentication mechanism, allowing a remote attacker to bypass authentication and gain unauthorized access to protected services.

CVE-2026-7166
Critical

The vulnerability involves the exposure of sensitive data, such as email addresses and phone numbers, without adequate protection. Sensitive information is also accessible in the local database, including data on minors and municipal users.

CVE-2026-7165
Critical

The vulnerability exists in the '/addJugador' endpoint, where the 'keyJugador' and 'keyJugadorObjectiu' parameters allow modification of other users' information without authorization validation. Additionally, the 'punts' and 'numObjectiusEliminats' fields permit arbitrary data to be added, potentially leading to fraud related to rewards.

CVE-2026-6653
Critical

A Use After Free vulnerability in the xmlParseInternalSubset function of libxml2 versions 2.9.11 through 2.11.0 allows a remote attacker to cause a denial-of-service (DoS) via specially crafted XML input with improper entity resolution.
