CVE-2026-83537 Medium · 5.3 CWE-345 Sep 9, 2026
WP Express Checkout < 2.5.0 - Unauthenticated Payment Bypass via wpec_process_empty_payment
The WP Express Checkout WordPress plugin before 2.5.0 does not verify server-side that a payment was actually completed before marking an order as paid, allowing unauthenticated users to forge a completed order without paying.
CVE-2026-73316 High · 7.5 CWE-345 Sep 8, 2026
XenForo < 2.3.13 Payment Replay via PayPal REST Payment Provider
XenForo before 2.3.13 contains a payment replay vulnerability in the PayPal REST payment provider that allows attackers to process the same webhook payload multiple times by exploiting a missing duplicate transaction ID check. Attackers can replay a valid webhook payload to trigger duplicate payment events, resulting in repeated subscription activations and unauthorized account upgrades.
CVE-2026-85008 Medium · 5.3 CWE-345 Sep 4, 2026
undici vulnerable to caching and replay of unsafe HTTP method responses
undici's cache interceptor documents that only safe HTTP methods are cached, but its logic to skip caching is built by subtracting the configured methods from the set of safe methods, so an unsafe method such as POST, PUT, or DELETE is never placed in the skip list and instead falls through to the full cache-read path. The response-storage gate also lacked a method check, so a response to an unsafe request that is heuristically cacheable or carries an explicit Cache-Control directive is stored and later replayed from cache. Because response headers from a remote origin are untrusted, an origin can answer once with a cacheable status and then have the client's own subsequent state-changing requests to that path served from the stale cache entry without ever reaching the origin, an integrity failure that occurs under the interceptor's default configuration. This affects undici versions from 7.0.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2.
CVE-2026-85621 Medium · 6.5 CWE-345 Sep 4, 2026
LobeChat 2.2.1 Webhook Signature Verification Bypass QQ Feishu
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-2026-84043 Medium · 5.3 CWE-345 Sep 4, 2026
ePayco Payment Gateway for WooCommerce < 8.4.7 - Unauthenticated Payment Confirmation Bypass

MOOS-IvP through 24.8.1 uFldNodeBroker Unauthenticated Shore Route Enrollment
MOOS-IvP uFldNodeBroker through 24.8.1 fails to validate the source of TRY_SHORE_HOST messages on the vehicle bus, allowing any publisher to enroll attacker-controlled shore routes. Attackers can publish malicious shore route messages to receive bridged vehicle traffic including sensor data and control information.
CVE-2026-85434 Critical · 9.1 CWE-345 Sep 3, 2026
MOOS-IvP through 24.8.1 uFldShoreBroker Bridge Route Injection via Unverified Node Ping
MOOS-IvP uFldShoreBroker through 24.8.1 fails to verify node ping authenticity before creating outbound bridge routes. Attackers can publish NODE_BROKER_PING messages with crafted HostRecord data to redirect bridged variables to attacker-controlled addresses.
CVE-2026-85431 High · 7.5 CWE-345 Sep 3, 2026
MOOS essential-moos through 10.0.1 pMOOSBridge Unauthenticated UDP Packet Injection
MOOS essential-moos through version 10.0.1 contains an unauthenticated UDP packet injection vulnerability in pMOOSBridge when configured with UDPListen. Attackers can send crafted UDP packets to the configured port to inject arbitrary variables into the local MOOS community with spoofed source and community identifiers.
CVE-2026-85430 Critical · 9.1 CWE-345 Sep 3, 2026
MOOS essential-moos through 10.0.1 pShare Unauthenticated UDP Datagram Republishing
MOOS essential-moos through 10.0.1 contains an authentication bypass vulnerability in pShare that accepts UDP datagrams from any source and republishes them with the attacker-claimed identity intact. Attackers can send crafted UDP datagrams to pShare input routes to inject messages into the local MOOS community under spoofed identities, or send malformed datagrams to crash the pShare process.
CVE-2026-85429 High · 7.5 CWE-345 Sep 3, 2026
MOOS-IvP through 24.8.1 uFldNodeComms Node Message Source Spoofing
MOOS-IvP uFldNodeComms through 24.8.1 trusts the source node identity from the message body rather than validating it from the connection source. Attackers can craft NODE_MESSAGE packets with spoofed source identities to impersonate other nodes and post arbitrary variable notifications without validation.
CVE-2026-53728 High · 7.1 CWE-345 Sep 3, 2026
Medplum - Improper Validation of Redirect URI in External Auth Callback allows Authorization Code Leakage
Medplum is a developer platform that enables development of healthcare apps. Prior to version 5.1.6, the external identity provider callback at GET /auth/external accepts attacker-controlled redirect URIs that only need to start with a registered client redirect URI, rather than matching exactly. After a successful external IdP login, the server appends Medplum login and code values to that attacker-supplied URL and issues a redirect. Because the external login request state is serialized as raw JSON and later trusted by the callback, an attacker who can tamper with state.redirectUri can cause Medplum to redirect authorization artifacts to an attacker-controlled endpoint. When the registered redirect URI is a bare origin or another prefix that can be extended into a different hostname, this becomes a cross-origin authorization code leak. This issue has been patched in version 5.1.6.

CVE-2026-20355 Medium · 5.9 CWE-345 Sep 2, 2026
Cisco Secure Email S/MIME Ciphertext Decryption Vulnerabilty
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.

DialogHandler UploadPaths Tampering Vulnerability in Telerik UI for ASP.NET AJAX
In Progress® Telerik® UI for AJAX prior to v2026.3.812, insufficient integrity protection of dialog request parameters used by the RadEditor file browser may allow an attacker who has obtained certain application encryption key material to alter the folders the file browser reads from, writes to, and uploads into, potentially resulting in remote code execution.
CVE-2026-79621 Medium · 4.3 CWE-345 Sep 2, 2026
CatalogX < 6.1.3 - Unauthenticated Email Content Injection via Shared Transient
The CatalogX WordPress plugin before 6.1.3 does not sanitise or escape content that an unauthenticated user can store before including it in the product enquiry notification email sent to the site administrator, allowing unauthenticated attackers to inject arbitrary content into that email, which is delivered when an unrelated visitor later submits a product enquiry.

pac4j-saml before 6.5.6 does not require signature validation of SAML LogoutRequest messages in SAML2LogoutValidator.validateLogoutRequest(). When an IdP sends no SessionIndex, a session can be destroyed based solely on the NameID, allowing an unauthenticated attacker to submit an unsigned LogoutRequest with a guessed identifier (e.g., an email address used as NameID) to terminate a victim's SAML session.

CVE-2026-82017 High · 7.6 CWE-345 Aug 28, 2026
IGEL OS 12 / 11 Boot Registry Parameter Injection via Unsigned Configuration Area
IGEL OS 12 before 12.7.6 and IGEL OS 11 before 11.11.150 contain a boot registry parameter injection vulnerability that allows attackers with physical access to execute arbitrary Linux loader parameters by writing to an unencrypted and unsigned configuration area read by the signed bootloader. Attackers can inject malicious kernel command line parameters that execute with boot environment privileges without triggering TPM PCR measurement failures, as the attack does not modify the measured boot code.
