CVE-2026-14199 1 Grafana 2 Grafana, Grafana Enterprise 2026-09-03 7.1 High
Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).
CVE-2026-12704 1 Grafana 1 Grafana Enterprise 2026-09-03 6.8 Medium
When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and gain a session as the victim user. Only instances with the allow_idp_initiated SAML setting enabled are affected; this setting is off by default and Grafana OSS is not affected.
CVE-2026-0872 2 Thales, Thalesgroup 2 Safenet Agent For Windows Logon, Safenet Agent For Windows Logon 2026-09-03 N/A
Improper Certificate Validation vulnerability in Thales SafeNet Agent for Windows Logon on Windows allows Signature Spoofing by Improper Validation. This issue affects SafeNet Agent for Windows Logon: 4.0.0, 4.1.1, 4.1.2.
CVE-2026-82955 1 Eclipse Foundation 1 Eclipse Aerios 2026-09-03 N/A
In the current development version of Eclipse aeriOS, which has not yet had an official release, the KrakenD instance included in the API Gateway component had the disable_jwk_security parameter hard-coded to true, with no option to override it through the Helm chart configuration. This setting disables TLS certificate verification when KrakenD retrieves the JSON Web Key Set (JWKS) used to validate bearer tokens, potentially allowing an attacker with the ability to intercept this communication to provide a malicious JWKS and compromise token validation. The issue has been addressed by making the parameter configurable through the boolean Helm value krakend.config.disableJwkSecurity and setting its default value to false, ensuring that TLS certificate verification is enabled by default.
CVE-2026-82180 1 Eclipse 1 Arrowhead 2026-09-03 N/A
In Eclipse Arrowhead versions from 5.0.0 to 5.2.1 when the MQTT API is enabled with the certificate authentication policy, CertificateMqttFilter parses an X.509 certificate that the client sends inside the MQTT message payload (the authentication field of MqttRequestTemplate) and treats its Subject DN as the authenticated identity. The certificate is decoded with CertificateFactory.generateCertificate() but its signature is never verified and its issuer chain is never validated against any trust store. Authorisation is reduced to two string comparisons on attacker-supplied data: the DN-qualifier must equal "sy" or "op", and the cloud-name part of the CN must match the server's. Both values are public (the cloud name is in the server's own TLS certificate). An attacker who can publish to the MQTT broker can therefore mint a self-signed certificate with CN=Sysop.<cloud>.<org>.arrowhead.eu, dnQualifier=op, send it as the authentication field, and be authenticated as the cloud's system operator with isSysOp == true. This passes the downstream ManagementServiceMqttFilter (request.isSysOp() → allowed) and gives full management access over MQTT. The HTTP CertificateFilter is not affected — it reads the certificate from jakarta.servlet.request.X509Certificate, which Tomcat populates only after a successful mTLS handshake against the configured trust store.
CVE-2026-53636 1 Openedx 1 Edx-platform 2026-09-03 4.7 Medium
Open edX Platform enables the authoring and delivery of online learning at any scale. Prior to commit 3a5ac85, a security vulnerability has been identified in the Open edX LMS platform's LTI (Learning Tools Interoperability) Provider implementation. The validate_timestamp_and_nonce function in lms/djangoapps/lti_provider/signature_validator.py does not validate OAuth nonces or timestamps, allowing an attacker who captures a valid LTI launch request to replay it an unlimited number of times without detection. This issue has been patched via commit 3a5ac85.
CVE-2026-19117 1 Delinea 1 Secret Server 2026-09-03 9.8 Critical
Under specific conditions, an attacker can register an attacker-controlled FIDO2 credential against a target account and then authenticate as that user. This issue affects on-premises deployments only.
CVE-2026-85221 1 Misp 1 Misp 2026-09-03 N/A
MISP contains an improper TLS certificate validation vulnerability in CurlClient. The CurlClient::$verifyPeer property was not explicitly initialized and therefore defaulted to null. When passed to cURL, this value effectively disabled TLS peer verification unless the calling code explicitly enabled it. As a result, HTTPS connections made through affected CurlClient instances could accept certificates that were not issued by a trusted certificate authority. An attacker capable of intercepting or manipulating network traffic between a MISP instance and a remote HTTPS service could impersonate the remote endpoint and perform a man-in-the-middle attack. Successful exploitation could allow an attacker to observe sensitive information transmitted by MISP, including authentication material or exchanged threat intelligence, and to modify responses returned to the MISP instance. The impact depends on the functionality using CurlClient and the data exchanged with the remote service. The patch enables TLS peer verification by default while preserving explicit support for configured self-signed certificates. It also corrects the self-signed certificate handling in SyncTool so that peer verification is disabled only when no pinned CA certificate is configured.
CVE-2026-73742 2 Arubanetworks, Hewlett Packard Enterprise (hpe) 2 Fabric Composer, Fabric Composer 2026-09-03 4.3 Medium
A vulnerability in an API endpoint of HPE Networking Fabric Composer could allow an authenticated low privilege operator user to spoof the source address attributed to their requests. Successful exploitation could allow an attacker to cause inaccurate attribution information to be recorded on the affected system.
CVE-2026-42013 2 Gnu, Redhat 15 Gnutls, Discovery, Enterprise Linux and 12 more 2026-09-03 8.2 High
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks.
CVE-2026-42011 1 Redhat 14 Discovery, Enterprise Linux, Enterprise Linux Eus and 11 more 2026-09-03 7.4 High
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
CVE-2026-58062 2 Bouncycastle, Legion Of The Bouncy Castle Inc. 6 Bc-java, Bouncy Castle For Java Lts, Fips Java Api and 3 more 2026-09-02 9.1 Critical
In Bouncy Castle for Java before 1.85, Stapled OCSP response accepted without binding to the checked certificate. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bc-fips 2.0.2 (2.0.X series) and 2.1.3 (2.1.X series).
CVE-2026-8763 2 Bouncycastle, Legion Of The Bouncy Castle Inc. 6 Bc-java, Bouncy Castle For Java Lts, Fips Java Api and 3 more 2026-09-02 9.1 Critical
In Bouncy Castle for Java before 1.85, Name Constraints bypass via trailing dot in rfc822Name and URI. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bc-fips 1.0.2.7 (1.0.X series), 2.0.2 (2.0.X series) and 2.1.3 (2.1.X series).
CVE-2026-69248 1 Pyca 1 Cryptography 2026-09-02 N/A
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In versions 45.0.0 through 48.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of *.example.com, python-cryptography's verifier accepts which allows escaping outside of the permitted names. The core issue is in DNSConstraint::matches, where a wildcard pattern was treated as matching a more-specific permitted constraint even though *.example.com can expand to sibling names such as bar.example.com outside foo.example.com. This allows acceptance of an invalid certificate chain. This issue is fixed in 49.0.0.
CVE-2026-39835 1 Golang 2 Crypto, Ssh 2026-09-02 5.3 Medium
SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
CVE-2026-84479 1 Wwbn 1 Avideo 2026-09-02 9.1 Critical
WWBN AVideo (current e01e41ecc and earlier) makes three login-time security controls depend solely on the client-supplied User-Agent header. The isAVideoEncoder()/isAVideoMobileApp() checks match HTTP_USER_AGENT against a hardcoded literal ("AVideoEncoder"/"AVideoMobileApp") with no IP check or shared secret. An attacker who submits valid credentials and sets User-Agent: AVideoEncoder bypasses two-factor authentication, skips brute-force captcha escalation, and avoids being recorded in the login/device audit history. No patch is available at the time of publication.
CVE-2026-84476 1 Wwbn 1 Avideo 2026-09-01 7.5 High
WWBN AVideo fails to validate trusted proxies before accepting X-Real-IP and X-Forwarded-For headers, allowing attackers to spoof the client address used by enforceRateLimit(). Attackers can rotate the header value per request to bypass login rate limiting and perform unlimited credential guessing attacks.
CVE-2026-66795 1 Redhat 1 Multicluster Engine 2026-09-01 9.9 Critical
A flaw was found in the managedcluster-import-controller. The Certificate Signing Request (CSR) auto-approval logic improperly validates incoming CSRs, specifically by not inspecting the signer name or decoding the PEM-encoded x509 CSR. This vulnerability allows a privileged service account on a spoke cluster to submit a malicious CSR. Successful exploitation can lead to privilege escalation, enabling the attacker to obtain administrative credentials on the hub cluster.
CVE-2026-58575 1 Dell 12 Powerstore 1000t, Powerstore 1200t, Powerstore 3000t and 9 more 2026-09-01 8.8 High
Dell PowerStore contains an Authentication Bypass by Spoofing vulnerability. An authenticated attacker could potentially exploit this vulnerability to escalate privileges to Administrator.
CVE-2026-82228 2 Siteground, Wordpress 2 Siteground Security, Wordpress 2026-09-01 8.1 High
Unauthenticated Bypass Vulnerability in SiteGround Security <= 1.6.6 versions.
