CVE-2026-52767 1 Yeswiki 1 Yeswiki 2026-09-08 8.2 High
YesWiki is a wiki system written in PHP. From version 4.6.2 to before version 4.6.6, HttpSignatureService::verifySignature() checks the result of PHP's openssl_verify() with a loose boolean negation - if (!openssl_verify(...)) { throw ... }. PHP's openssl_verify has four possible return values: 1, 0, -1, and "false". The -1 row is the bypass: PHP's truthiness rules make -1 a truthy value, so !(-1) === false, the throw is skipped, and the controller proceeds to processActivity(). Any condition that makes OpenSSL's EVP_VerifyFinal() return -1 triggers the bypass. The reachable consequence is the controller silently treats a failed verification as success and processes the attacker's payload. This issue has been patched in version 4.6.6.
CVE-2026-14296 1 Nordic Semiconductor Asa 1 Nrf54h20 2026-09-08 7.5 High
When using the Direct XIP update strategy, the main application image starts other cores (i.e. radio core), based on the currently active slot without additional verification. The MCUboot in the bare (upstream) configuration assumes that if there is at least a single slot for each image available, the system is bootable and continues the boot process. This may lead to a situation when MCUboot picks different slot for different images (i.e. (a) for the main application and (b) for the radio image), boots the main application (from slot (a)) that afterwards starts the radio image by providing an address of the unauthenticated slot ((a) instead of (b)).
CVE-2026-66776 2 Sap, Sap Se 2 Approuter, Sap Business Ai Platform (approuter) 2026-09-08 5.9 Medium
SAP Approuter does not consistently enforce integrity verification on certain session-related request headers under specific conditions. An attacker with low privileges could send a specially crafted request that bypasses the integrity check and loads another user's session context. Successful exploitation requires the attacker to have previously observed matching session values out-of-band, which makes the attack complex to execute. This could result in a high impact on confidentiality and a low impact on integrity. There is no impact on availability.
CVE-2026-69559 1 Microsoft 1 Teams 2026-09-08 5.8 Medium
Origin validation error in Microsoft Teams for Android allows an authorized attacker to disclose information over a network.
CVE-2026-86304 1 Perl 1 Mojox::authentication 2026-09-08 9.8 Critical
MojoX::Authentication versions before 0.006 for Perl allow SAML authentication bypass because parse_assertion builds Net::SAML2::Binding::POST without a trust anchor. parse_assertion in MojoX::Authentication::Model::SAML2 calls Net::SAML2::Binding::POST->new with no cacert, cert_text or anchors argument, then passes the returned XML to Net::SAML2::Protocol::Assertion->new_from_xml with the IdP signing certificate as cacert. In Net::SAML2 before 0.86 that certificate guards only encrypted assertions, so the signature on an unencrypted assertion is checked against the certificate the response itself carries. An attacker starts a SAML login, then posts a response signed with a certificate of their own. The audience, InResponseTo and timestamp checks that follow are all satisfiable by the attacker, so the response authenticates any NameID it carries.
CVE-2026-80098 1 Microsoft 1 Copilot Studio 2026-09-08 9.3 Critical
Improper verification of cryptographic signature in Copilot Studio allows an unauthorized attacker to elevate privileges over a network.
CVE-2026-20355 1 Cisco 1 Secure Email 2026-09-08 5.9 Medium
Multiple vulnerabilities in the Secure/Multipurpose Internet Mail Extensions (S/MIME) decryption functionality of Cisco Secure Email could allow an unauthenticated, remote attacker to recover plain text from encrypted email messages. These vulnerabilities are due to insufficient validation of message integrity. An attacker could exploit these vulnerabilities by using a machine-in-the-middle technique to intercept and modify traffic between email gateways. A successful exploit could allow the attacker to obtain plaintext content from the encrypted communication.
CVE-2023-20576 2026-09-04 7.7 High
Insufficient Verification of Data Authenticity in AGESA™ may allow an attacker to update SPI ROM data potentially resulting in denial of service or privilege escalation.
CVE-2026-84185 2 Red Hat, Redhat 6 Red Hat Openshift Ai (rhoai), Ansible Automation Platform, Enterprise Linux and 3 more 2026-09-04 5.9 Medium
A flaw was found in the jwcrypto library, which is used for implementing Javascript Object Signing and Encryption (JOSE) standards. The issue occurs when the library verifies a General JSON Serialization JWS using a set of keys. Due to a coding error, the library fails to correctly identify the specific key ID (kid) and may instead accept a signature made by any valid key in the set. This can allow an attacker with a valid key to bypass authorization checks in applications that rely on the key ID to identify specific tenants or users.
CVE-2026-84043 2026-09-04 5.3 Medium
The ePayco Payment Gateway for WooCommerce WordPress plugin before 8.4.7 does not properly verify the authenticity of payment confirmation requests, allowing unauthenticated attackers to mark orders as paid without a valid gateway signature.
CVE-2026-84767 2 Nexcess, Wordpress 2 Bookit, Wordpress 2026-09-04 5.3 Medium
Unauthenticated Bypass Vulnerability in BookIt <= 2.6.0.3 versions.
CVE-2026-73776 2 Hewlett Packard Enterprise (hpe), Hpe 157 Aos-cx, Aruba Cx 10000-48y6c \(r8p13a\), Aruba Cx 10000-48y6c \(r8p14a\) and 154 more 2026-09-04 7.9 High
A signature verification bypass vulnerability exists in the command line interface of AOS-CX. Successful exploitation could allow an authenticated malicious actor with administrative privileges to execute arbitrary code on the underlying operating system, when certain pre-conditions outside of the attacker’s control are met.
CVE-2026-85621 1 Lobehub 1 Lobehub 2026-09-04 6.5 Medium
LobeChat (LobeHub) 2.2.1 does not properly verify inbound chat-platform webhook signatures in the QQ and Feishu adapters. The webhook route (/api/agent/webhooks/:platform) is unauthenticated by design and delegates verification to each adapter; the QQ adapter performs no Ed25519 signature verification on dispatched message events, and the Feishu adapter only performs an optional static-token comparison that is skipped when no token is configured (the default) and is not a body signature. An unauthenticated attacker who knows the public webhook URL can POST forged inbound messages with an attacker-chosen sender identity and arbitrary text, causing the bot owner's agent to process attacker-controlled input and treat the attacker as a trusted platform sender.
CVE-2026-18248 1 Fastify 2 Aws-lambda, Fastify\/aws-lambda 2026-09-04 9.1 Critical
@fastify/aws-lambda version 6.4.0 decorates each Fastify request with request.awsLambda.event and request.awsLambda.context, values that applications are documented to use for authorization decisions such as reading API Gateway authorizer claims. In the default configuration, the getter that populates this decoration reads the client-controlled x-apigateway-event and x-apigateway-context HTTP headers before falling back to the trusted internal request token, and those reserved headers are not stripped from the incoming event. An unauthenticated attacker who can set a single HTTP header can therefore forge the entire Lambda proxy event, including the authorizer context, and override the genuine one. This results in a full authentication and authorization bypass and privilege escalation for any application that trusts request.awsLambda.event for identity or access control. Only version 6.4.0 is affected. Patches: upgrade to @fastify/aws-lambda 6.4.1, which resolves the decoration only through the internal per-invocation token and strips the reserved headers before the request is processed.
CVE-2026-18500 1 Fastify 2 Fastify\/jwt, Jwt 2026-09-04 8.1 High
@fastify/jwt is a JSON Web Token plugin for Fastify. In versions before 10.2.2, a per-request verification key passed to request.jwtVerify({ key }) is silently overridden by the plugin's globally configured secret, because the option merge applies the global key last. Applications that use different keys for different authorization domains, for example separate user and admin keys, therefore accept a token signed with the global key on a route that explicitly requires another key. This lets an ordinary authenticated user cross a key-based trust boundary without knowing either secret. The issue is fixed in @fastify/jwt 10.2.2, where an explicit per-call key takes precedence over the global secret. Users should upgrade to 10.2.2.
CVE-2026-84133 1 Mozilla 2 Firefox, Thunderbird 2026-09-03 9.8 Critical
Site isolation issue in the DOM: Push Subscriptions component. This vulnerability was fixed in Firefox 155, Firefox ESR 153.2, Thunderbird 155, and Thunderbird 153.2.
CVE-2026-85393 1 Digitalbazaar 1 Forge 2026-09-03 7.5 High
node-forge through 1.4.0 fails to validate element count in nested DigestAlgorithm sequences during RSA PKCS#1 v1.5 signature verification. Attackers can embed garbage bytes inside the DigestAlgorithm sequence to forge valid signatures for arbitrary messages using low-exponent RSA keys. This is an incomplete fix for CVE-2026-33894.
CVE-2026-80465 1 Siemens 3 Mendix Saml (mendix 10 Compatible), Mendix Saml (mendix 11 Compatible), Mendix Saml (mendix 9.24 Compatible) 2026-09-03 8.7 High
