CVE-2026-40498

Improper certificate validation in Microsoft Partner Center allows an unauthorized attacker to elevate privileges over a network.

Authorization bypass through user-controlled key in Microsoft Bookings allows an unauthorized attacker to elevate privileges over a network.

Deserialization of untrusted data in Microsoft Dataverse allows an unauthorized attacker to execute code over a network.

Missing authentication for a critical function in Azure App Service allows an unauthorized attacker to execute code over a network.

Missing authorization in Azure SRE Agent allows an authorized attacker to elevate privileges over a network.

IBM Guardium Data Protection 12.2 and 12.2.2 could allow a remote attacker to execute arbitrary management operations due to missing authentication for a critical function.

IBM Guardium Data Protection 12.0, 12.1, and 12.2 could allow a remote attacker to execute unauthorized SQL statements due to SQL injection.

IBM Guardium Data Protection 12.0, 12.1, and 12.2 could allow a remote attacker to execute arbitrary code due to path traversal.

Hazelcast prior to 5.4.5, 5.5.10, and 5.6.1 contains improper validation of data supplied by a malicious client able to connect to a cluster, allowing arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations, corrupt memory with possible arbitrary code execution. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.

fast-jwt from 6.2.0 until 6.3.0 can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
