| CVE-2026-84465 | 2026-09-25 | N/A | ||
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when Zammad checks the digital signature on an incoming S/MIME-signed email, it does not verify that the signing certificate is genuinely trusted, it only checks whether a certificate with a matching name is already stored in the system. An attacker can create their own certificate using the name of a real, previously trusted sender and use it to send a forged email. Zammad will display that email with the same "validly signed" indicator as a genuine message from the real sender, even though the attacker never had access to that sender's actual certificate or private key. This issue is fixed in version 7.1.2. | ||||

| CVE-2026-15554 | 1 Redhat | 4 Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Els, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-09-25 | 7.4 High |
| the Undertow AJP listener honours forged ssl_cert and is_ssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP protocol. | ||||
| CVE-2026-67231 | 1 Rabbitmq | 1 Rabbitmq-server | 2026-09-24 | 8.1 High |
| RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, The trust-store plugin installs a verify_fun that overrides {bad_cert, unknown_ca} / {bad_cert, selfsigned_peer} when the presented cert "matches" a whitelisted one. The match key is extract_issuer_id/1 → public_key:pkix_issuer_id/2 → {IssuerName, SerialNumber} , both fields are taken verbatim from the presented certificate body and contain no public-key, SKI, fingerprint or signature material. is_whitelisted/1 is a pure ets:member lookup; the stored full DER is used only for list/0 display and is never compared against the presented cert. cacerts is [], so the whitelisted cert is never used as a trust anchor for path validation either. TLS client-authentication bypass: an attacker who knows the issuer DN + serial of any whitelisted certificate can connect with a forged self-signed cert. Preconditions include rabbitmq_trust_store plugin enabled and used as the TLS verify_fun Attacker knows or can guess the {Issuer, Serial} of at least one whitelisted cert (non-secret; exposed via CLI/logs/any cert copy). This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0. | ||||
| CVE-2026-91812 | 1 Foxitsoftware | 2 Foxit Pdf Editor, Foxit Reader | 2026-09-24 | 7.9 High |
| A vulnerability in Foxit PDF Editor/Reader’s update mechanism allows man-in-the-middle attackers to bypass certificate validation and package integrity checks, potentially enabling arbitrary code execution with system privileges. | ||||
| CVE-2026-67404 | 1 Rabbitmq | 1 Rabbitmq-server | 2026-09-23 | N/A |
| RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, When no CA bundle is available, ssl_options/1 falls back to [{verify, verify_none}] with no warning. An attacker in a man-in-the-middle position can forge the JWKS response, which leads the broker to accept arbitrary JWTs. Preconditions include The OAuth2 plugin must be in use with no cacertfile configured and the OS CA bundle empty or unreadable (for example, in a minimal container), and the attacker must hold a network man-in-the-middle position.. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0. | ||||
| CVE-2026-81868 | 1 Steeltoeoss | 1 Security-advisories | 2026-09-23 | 6.5 Medium |
| Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. Prior to 4.3.0, Steeltoe.Security.Authorization.Certificate deployments using AddOrgAndSpacePolicies() and UseCertificateAuthorization() trust the public certificate supplied in the X-Client-Cert request header without proving possession of the corresponding private key. Common Cloud Foundry routers do not remove this header from inbound requests. When inbound requests are not restricted to a known trusted proxy source IP, an attacker who obtains the public certificate of an application instance in the target organization or space and can reach the application can spoof X-Client-Cert to bypass the SameOrg and SameSpace policies for the certificate validity period. This issue is fixed in version 4.3.0. | ||||
| CVE-2026-18173 | 1 Ibm | 1 Financial Transaction Manager Ftmfor Redhat Openshift | 2026-09-23 | 3.7 Low |
| IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to obtain sensitive information due to improper enforcement of mutual TLS authentication. | ||||
| CVE-2026-85102 | 1 Checkpoint | 46 Gaia Embedded, Gaia Os, Quantum 3600 and 43 more | 2026-09-23 | 9.8 Critical |
| Improper certificate trust validation during VPN negotiation in Check Point Quantum Security Gateway may allow an unauthenticated remote attacker to execute arbitrary code on the Gateway. | ||||
| CVE-2026-93602 | 1 Rustls | 1 Webpki | 2026-09-22 | 4.4 Medium |
| rustls-webpki versions before 0.103.10 and 0.104.0-alpha.5 contain faulty CRL authority-matching logic that compares only the first distributionPoint against each CRL's IssuingDistributionPoint, ignoring additional distributionPoints. Attackers with a compromised trusted issuing authority can present revoked certificates that pass revocation checks under UnknownStatusPolicy::Allow, or cause incorrect errors under the default deny policy. | ||||
| CVE-2026-93600 | 1 Rustls | 1 Webpki | 2026-09-22 | 2.2 Low |
| rustls-webpki (rustls/webpki) versions 0.101.0 through 0.103.11 and 0.104.0-alpha releases before 0.104.0-alpha.6 ignore X.509 name constraints that apply to URI names, causing such constraints to be accepted rather than enforced. Because name constraints are restrictions on otherwise properly issued certificates, the flaw is only reachable after successful signature verification and requires a misissued certificate to exploit; the library also provides no API for asserting URI names, and URI name constraints are otherwise unimplemented. Versions 0.103.12 and 0.104.0-alpha.6 reject URI name constraints unconditionally. | ||||
| CVE-2026-93601 | 1 Rustls | 1 Webpki | 2026-09-22 | 2.2 Low |
| rustls-webpki (the Rust webpki fork used by rustls) versions >= 0.101.0 and prior to 0.103.12 and 0.104.0-alpha.6 incorrectly accepted permitted-subtree DNS name constraints for certificates asserting a wildcard name. For example, a name constraint of accept.example.com was treated as satisfied by a certificate for *.example.com, which could feasibly assert reject.example.com — a name outside the permitted subtree. Because name constraints are restrictions applied to otherwise properly issued certificates, the issue is only reachable after signature verification succeeds and requires a misissued wildcard certificate to exploit. | ||||
| CVE-2026-65118 | 1 Nvidia | 1 Infrastructure Controller | 2026-09-22 | 7.5 High |
| NVIDIA Infrastructure Controller for Linux contains a vulnerability where an attacker could cause improper certificate validation. A successful exploit of this vulnerability might lead to information disclosure, data tampering, and denial of service. | ||||
| CVE-2026-65129 | 1 Nvidia | 1 Infrastructure Controller | 2026-09-22 | 6.7 Medium |
| NVIDIA Infrastructure Controller for Linux contains a vulnerability where an attacker could cause improper certificate validation. A successful exploit of this vulnerability might lead to information disclosure, data tampering, and denial of service. | ||||
| CVE-2026-63374 | 1 Agronholm | 1 Anyio | 2026-09-22 | N/A |
| AnyIO is a high level asynchronous concurrency and networking framework that works on top of either Trio or asyncio. Prior to 4.14.2, connect_tcp() and TLSStream.wrap() can validate internationalized host names after the standard library converts them with IDNA 2003 instead of IDNA 2008. When a connection to a non-ASCII domain is hijacked or redirected, an attacker can obtain a legitimate certificate for the different ASCII hostname produced by IDNA 2003 and present it to the client, causing the malicious endpoint's certificate to validate. This issue is fixed in version 4.14.2. | ||||
| CVE-2026-87608 | 1 Google | 1 Chrome | 2026-09-21 | 7.5 High |
| Improper certificate validation in FedCM in Google Chrome prior to 153.0.8010.36 allowed a remote attacker leveraging social engineering to bypass web origin policy via crafted network traffic. (Chromium security severity: Low) | ||||
