fast-jwt provides fast JSON Web Token (JWT) implementation. From 6.2.0 until 6.3.0, fast-jwt 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.
Hazelcast is a unified real-time data platform combining stream processing with a fast data store. Prior to 5.4.5, 5.5.10, and 5.6.1, improper validation of data supplied by a malicious client able to connect to a cluster allows 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. Both slim and full distributions are affected. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.

A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders (src/serializers/decoders/*/decode_graph_entities.c) in FalkorDB before 4.18.1 allows a remote attacker who can issue Redis replication commands (for example, against an instance with no password configured) to cause a denial of service or execute arbitrary code in the redis-server process by supplying a crafted RDB stream whose deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.
A stack-based buffer overflow in the _RdbLoadEntity function of the RDB graph decoders (src/serializers/decoders/*/decode_graph_entities.c) in FalkorDB before 4.18.4 allows a remote attacker who can issue Redis replication commands (for example, against an instance with no password configured) to cause a denial of service and possibly execute arbitrary code by supplying a crafted RDB stream with an attacker-controlled entity property count. The count sizes two variable-length arrays on the thread stack with no upper bound, and the decoder then fills them with attacker-supplied values.
A heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function (src/serializers/serializer_io.c) in FalkorDB before 4.18.4 allows a remote attacker who can issue Redis replication commands (for example, against an instance with no password configured) to cause a denial of service or disclose heap memory by supplying a crafted RDB stream whose sub-buffer length field exceeds the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
A heap-based out-of-bounds write in the BoltReadHandler function (src/bolt/bolt_api.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly execute arbitrary code by sending a Bolt RESET message with an attacker-chosen chunk size to the Bolt port. The handler checks the size only with ASSERT(), which is compiled out in release builds, then computes a destination pointer from the wire-supplied 16-bit size and moves buffered data up to about 64 KiB backwards past the start of the read buffer. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
A heap-based out-of-bounds write in the ws_read_frame function (src/bolt/ws.c) and the buffer_apply_mask function (src/bolt/buffer.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly corrupt heap memory by sending a WebSocket frame with a 64-bit extended payload length to the Bolt port. The payload length is not bounded, and the only bounds check in buffer_apply_mask is an ASSERT(), which is compiled out in release builds, so the function XORs memory beyond the end of the receive buffer with the attacker-supplied mask key. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
An improper authentication vulnerability in the is_authenticated function (src/bolt/bolt_api.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to execute graph queries without credentials through the Bolt endpoint. The function decides whether a password is required by issuing an empty AUTH command to Redis and treats only a WRONGPASS error as meaning that a password is required; any other error, such as LOADING while a dataset is being loaded, MASTERDOWN during replication failover, or OOM under memory pressure, causes the client to be treated as authenticated. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
U.S. and allied agencies have disrupted infrastructure tied to Chinese-linked hacking tools used to scan networks, maintain long-term access, and steal emails, credentials, and other sensitive data from critical infrastructure and organizations worldwide. For CIOs and technology leaders, this underscores that nation-state adversaries are exploiting both legacy vulnerabilities and compromised routers/IoT devices at scale, making patch management, identity hardening, and segmentation across IT and OT environments a strategic priority rather than just a security task.
VMware Workstation and Fusion contain an integer-overflow vulnerability. A malicious actor with local administrative privileges on a virtual machine with VMXNET3 virtual network adapter may exploit this issue to execute code on the host. Affected versions: - VMware Workstation: 25H2, 26H1 (fixed in 26H1u1) - VMware Fusion: 25H2, 26H1 (fixed in 26H1u1)
This vulnerability exists in the ERP system due to unsafe deserialization of user controlled data in the affected functionality. An unauthenticated remote attacker could exploit this vulnerability by supplying specially crafted data to the vulnerable functionality of the targeted system. Successful exploitation of this vulnerability could allow the attacker to execute arbitrary code, manipulate application data or perform other unintended actions on the targeted system.
Express Gateway through 1.16.11 contains a hardcoded cryptographic key vulnerability that allows attackers with datastore access to decrypt stored OAuth 2.0 token secrets via the default crypto.cipherKey 'sensitiveKey'. Attackers who can read Redis can decrypt tokenEncrypted values and combine them with stored token IDs to obtain valid bearer tokens for any user.
Sungrow iSolarCloud before 2026 allows authentication bypass and account takeover via "login_type":"5" in a login request, potentially leading to "local blackouts on the whole continent" in Europe. An email address for the user_account property is required; however, a user can view the email address associated with their parent organization.
This advisory flags a critical Cisco vulnerability affecting the Application Policy Infrastructure Controller, with a CVSS score of 9.8, which signals urgent risk for environments that depend on Cisco ACI for network policy and operations. For CIOs, the business impact is potentially severe: a successful exploit could undermine infrastructure control, disrupt application delivery, and increase the risk of broader compromise, making rapid remediation and exposure assessment a priority for IT teams.
Cisco has issued a critical-severity security advisory for CVE-2026-76464 (CVSS 9.6), signaling a potentially serious risk to network infrastructure and the business services that depend on it. For CIOs and IT leaders, this means urgent prioritization of Cisco device exposure, rapid validation of compensating controls, and coordinated remediation to reduce the likelihood of outage, compromise, or broader operational disruption.
This critical Splunk Enterprise vulnerability affects versions below 10.4.3 and 10.2.7 and is reachable by an unauthenticated network user, making it a high-priority exposure for organizations that rely on Splunk for security monitoring and operational observability. For CIOs and IT leaders, the strategic risk is not just a potential service or platform compromise, but also loss of log integrity and visibility at the very point where incidents are detected and investigated, which can cascade into broader security and compliance impact.
