Due to improper RFC protocol validation in the SAP Kernel used by the Application Server ABAP of SAP NetWeaver and ABAP Platform, an unauthenticated attacker can send a crafted RFC request that exploits logical errors in memory management, leading to memory corruption. This could lead to a high impact on confidentiality and integrity with low impact on availability of the application.

CVE-2026-1238017.4 ALT—
——0SuperTokens Core is an open source authentication server. From 11.3.0 until 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1, SAML.handleCallback does not consume RelayState, record assertion identifiers, or enforce Response.InResponseTo. In the SP-initiated flow, an attacker who obtains a legitimately issued, still-valid SAML response and its matching RelayState can resubmit the pair to /recipe/saml/callback before the assertion's NotOnOrAfter time; in the IdP-initiated flow, the assertion can be replayed without RelayState. The missing Response.InResponseTo check also permits an in-progress login to be completed with an assertion for a different identity and fails to enforce allowIDPInitiatedLogin=false. The callback does not validate Destination or SubjectConfirmationData Recipient and NotOnOrAfter, and each accepted callback mints a fresh, independently redeemable authorization code carrying the captured user's identity. This issue is fixed in versions 11.3.8, 11.4.8, 12.0.11, 12.1.2, 12.2.1, and 12.3.1.16hCVE-2026-829079.8 CRÍ56.7%
——17Authentication Bypass by Capture-replay in ExternalLoginKeysManager in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker who captures a live externalLoginKey value to obtain a complete, cookie-free, reusable session as the user who issued it, in every webapp that user can reach, because checkExternalLoginKey runs as a global preprocessor ahead of both the CSRF and authentication checks and accepts the key as a bearer credential that is never bound to a client, never expires, and is not invalidated after use, while the framework itself both appends live keys to every cross-webapp link it renders and, via WidgetWorker's unvalidated inter-app link target, lets an authenticated user's key be attached to an attacker-chosen absolute URL and delivered directly to the attacker's own server. Users are recommended to upgrade to version 24.09.08, which fixes this issue.4dCVE-2026-1028949.1 CRÍ17.6%
——5GPUStack is an open-source GPU cluster manager for AI model serving and GPU instance provisioning. From 0.7.1 until 2.2.2, the /auth/saml/callback endpoint decoded SAML XML, used its NameID and attributes to resolve or provision a user, and minted a gpustack_session JWT without calling OneLogin_Saml2_Auth.process_response to verify the signature, issuer, audience, destination, or time conditions. Any network client could submit an identity for an existing user, including an administrator, or provision a new non-administrator account, even when SAML was not configured. Response and Assertion identifiers were not consumed, so captured signed responses could also be replayed. This issue is fixed in version 2.2.2.4dCVE-2026-1222207.4 ALT26.2%
——8WPO365 | LOGIN (wpo365-login) plugin before version 45.2 contains an authentication bypass by capture-replay vulnerability caused by a non-functional anti-replay check in Saml2_Service::check_message_id(), which never persists processed SAML message IDs to the wpo365_saml_message_ids transient due to a logic error that returns before saving. Attackers who capture a validly-signed SAMLResponse can replay it to the ACS endpoint repeatedly within its assertion validity window to log in as the victim, including administrators, without detection since the duplicate message ID check never triggers.5dCVE-2026-121640—40.8%
——12An Authentication Bypass by Capture-replay vulnerability in WatchGuard AuthPoint Gateway allows an attacker who has observed a legitimate request between AuthPoint Gateway components to replay it and perform unauthorized administrative actions, including disrupting authentication services.4dCVE-2026-11749—19.5%
——6A vulnerability has been identified in armeria-saml prior to 1.41.1, where bearer assertions are not enforced for one-time use, allowing replay of previously consumed assertion IDs within their validity period.13h
