CVE-2026-9802 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 6.8 MEDIUM
A flaw was found in Keycloak. When revokeRefreshToken=true is enabled and persistent session storage is in use, a server restart can reset internal timing mechanisms. This allows a remote attacker, who has previously captured a user's refresh token, to replay that token even after it has been revoked. Successful exploitation grants the attacker unauthorized access to the victim's account, potentially leading to information disclosure or privilege escalation.
CVE-2026-9801 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 4.9 MEDIUM
A flaw was found in Keycloak. A remote attacker with high privileges, such as a realm administrator configuring a malicious Lightweight Directory Access Protocol (LDAP) server or an attacker compromising an upstream LDAP server, could exploit this vulnerability. By sending a malformed LDAP password policy response during a password authentication request, the attacker can trigger an OutOfMemoryError. This causes the Keycloak Java Virtual Machine (JVM) to terminate, leading to a denial of service (DoS) for all realms on the affected node.
CVE-2026-9794 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 5.3 MEDIUM
A flaw was found in Keycloak. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted SOAP requests to the SAML ECP (Security Assertion Markup Language Enhanced Client or Proxy) endpoint with varying client IDs. By observing distinct faultstrings in the responses, the attacker can determine the client's protocol type, leading to information disclosure.
CVE-2026-9792 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 6.5 MEDIUM
A flaw was found in Keycloak's Client Policies, specifically within the `org.keycloak.protocol.oidc` component. When certain condition providers (client-type, client-roles, client-attributes, client-scopes) are used to enforce security restrictions, the `reject-ropc-grant` executor is silently bypassed. This allows an unauthenticated remote attacker to obtain tokens via a Resource Owner Password Credentials (ROPC) grant, even when a policy is explicitly configured to block it. This bypass can lead to unauthorized access and information disclosure.
CVE-2026-9791 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 4.3 MEDIUM
A flaw was found in Keycloak. An authenticated user with existing organization membership can exploit this flaw by accessing user-facing APIs, such as the account API or by requesting an OpenID Connect (OIDC) token with the 'organization' scope. This allows organization metadata to be disclosed in tokens, even after an administrator has explicitly disabled the Organizations feature, potentially leading to incorrect authorization decisions by resource servers.
CVE-2026-9704 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 6.8 MEDIUM
A flaw was found in Keycloak. An authenticated user with low privileges can exploit this vulnerability by sending an oversized subject_token JSON Web Token (JWT) to the TokenEndpoint. When the token exceeds a 4000-character limit, it is silently dropped, causing the system to fall back to client credentials. This allows the user to gain the permissions of the client's service account, leading to privilege escalation.
CVE-2026-7500 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 5.4 MEDIUM
When Keycloak is started with `--features-disabled=account,account-api`, the Account REST API is only partially disabled. Five endpoints under the versioned path `/account/v1alpha1` remain fully functional — including both read and write operations — because they lack the `checkAccountApiEnabled()` gate that correctly blocks four other endpoints in the same REST service class. The user needs to have permissions to use the API.
CVE-2026-4874 1 Redhat 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more 2026-06-26 N/A 3.1 LOW
A flaw was found in Keycloak. An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the `client_session_host` parameter during refresh token requests. This occurs when a Keycloak client is configured to use the `backchannel.logout.url` with the `application.session.host` placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure.
CVE-2026-37977 1 Redhat 1 Build Of Keycloak 2026-06-26 N/A 3.7 LOW
A flaw was found in Keycloak. A remote attacker can exploit a Cross-Origin Resource Sharing (CORS) header injection vulnerability in Keycloak's User-Managed Access (UMA) token endpoint. This flaw occurs because the `azp` claim from a client-supplied JSON Web Token (JWT) is used to set the `Access-Control-Allow-Origin` header before the JWT signature is validated. When a specially crafted JWT with an attacker-controlled `azp` value is processed, this value is reflected as the CORS origin, even if the grant is later rejected. This can lead to the exposure of low-sensitivity information from authorization server error responses, weakening origin isolation, but only when a target client is misconfigured with `webOrigins: ["*"]`.
CVE-2025-31181 2 Gnuplot, Redhat 2 Gnuplot, Enterprise Linux 2026-06-26 N/A 6.2 MEDIUM
A flaw was found in gnuplot. The X11_graphics() function may lead to a segmentation fault and cause a system crash.
CVE-2024-49395 3 Mutt, Neomutt, Redhat 3 Mutt, Neomutt, Enterprise Linux 2026-06-26 N/A 5.3 MEDIUM
In mutt and neomutt, PGP encryption does not use the --hidden-recipient mode which may leak the Bcc email header field by inferring from the recipients info.
CVE-2024-49394 3 Mutt, Neomutt, Redhat 3 Mutt, Neomutt, Enterprise Linux 2026-06-26 N/A 5.3 MEDIUM
In mutt and neomutt the In-Reply-To email header field is not protected by cryptographic signing which allows an attacker to reuse an unencrypted but signed email message to impersonate the original sender.
CVE-2024-49393 3 Mutt, Neomutt, Redhat 3 Mutt, Neomutt, Enterprise Linux 2026-06-26 N/A 6.5 MEDIUM
In neomutt and mutt, the To and Cc email headers are not validated by cryptographic signing which allows an attacker that intercepts a message to change their value and include himself as a one of the recipients to compromise message confidentiality.
CVE-2025-31180 2 Gnuplot, Redhat 2 Gnuplot, Enterprise Linux 2026-06-26 N/A 6.2 MEDIUM
A flaw was found in gnuplot. The CANVAS_text() function may lead to a segmentation fault and cause a system crash.
CVE-2025-31179 2 Gnuplot, Redhat 2 Gnuplot, Enterprise Linux 2026-06-26 N/A 6.2 MEDIUM
A flaw was found in gnuplot. The xstrftime() function may lead to a segmentation fault, causing a system crash.
CVE-2025-31178 2 Gnuplot, Redhat 2 Gnuplot, Enterprise Linux 2026-06-26 N/A 6.2 MEDIUM
A flaw was found in gnuplot. The GetAnnotateString() function may lead to a segmentation fault and cause a system crash.
CVE-2025-31176 2 Gnuplot, Redhat 2 Gnuplot, Enterprise Linux 2026-06-26 N/A 6.2 MEDIUM
A flaw was found in gnuplot. The plot3d_points() function may lead to a segmentation fault and cause a system crash.
CVE-2023-6478 4 Debian, Redhat, Tigervnc and 1 more 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-06-23 N/A 7.6 HIGH
A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information.
CVE-2023-6377 4 Debian, Redhat, Tigervnc and 1 more 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-06-23 N/A 7.8 HIGH
A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.
CVE-2023-5868 2 Postgresql, Redhat 16 Postgresql, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 13 more 2026-06-23 N/A 4.3 MEDIUM
A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory.
