Title
JupyterHub through 6.0.1 OAuth Client ID Collision via Unescaped Hyphen
Summary
JupyterHub through 6.0.1 contains an identifier collision vulnerability that allows authenticated users to overwrite another user's named-server OAuth client by registering a hyphenated username. Attackers holding a name like alice-prod can overwrite the client for alice's server prod, breaking OAuth login and revoking tokens by stopping their own server.

Title
SGLang through 0.5.20 Denial of Service via Duplicate bootstrap_room
Summary
SGLang through 0.5.20 in prefill/decode disaggregation mode fails to validate duplicate bootstrap_room fields in /generate requests with Mooncake KV transfer backend. Unauthenticated attackers can send concurrent requests with identical bootstrap_room values to crash scheduler processes or hang other users' requests until transfer timeout.

CVE-2026-78359 (GCVE-0-2026-78359)

Vulnerability from cvelistv5 – Published: 2026-10-12 06:49 – Updated: 2026-10-12 06:49

Title
Duplicate Identity / Identity Shadowing across CustomerUser backends
Summary
OTRS does not sufficiently enforce the uniqueness of customer user identities across multiple configured CustomerUser backends. When multiple backends, such as a database and LDAP, are configured, the uniqueness check for customer user email addresses is performed only within the selected backend. As a result, an authenticated user with permission to create or modify customer users may create a customer user whose email address is already assigned to a customer user in another backend. This can result in multiple customer user records representing the same communication identity. Depending on the affected workflow and backend resolution, customer-related information or email communication may subsequently be associated with or exposed to the wrong customer user. The vulnerability does not allow unauthenticated users to create customer accounts. Exploitation requires permissions to create or modify customer users. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected

Title
Traefik: Gateway API route identity collision allows cross-namespace backend hijacking
Summary
Traefik is an open source HTTP reverse proxy and load balancer. From 3.0.0 until 3.6.25 and 3.7.10, Traefik's Kubernetes Gateway API provider in pkg/provider/kubernetes/gateway/httproute.go, grpcroute.go, tcproute.go, and tlsroute.go builds HTTPRoute, GRPCRoute, TCPRoute, and TLSRoute router and service identities by hyphen-concatenating namespace, route name, Gateway identity, entry point, and rule index, allowing colliding Routes to overwrite another namespace's backend. This issue is fixed in 3.6.25 and 3.7.10.

CVE-2026-57024 (GCVE-0-2026-57024)

Title
Junos OS: MX with SPC3, SRX Series: Repeated VPN negotiation failures will eventually cause iked to crash continuously
Summary
A Use of Multiple Resources with Duplicate Identifier vulnerability in the IKE daemon (iked) of Juniper Networks Junos OS on MX with SPC3 and SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). On an MX with SPC3 and SRX devices configured for VPN service, when a large number of VPN negotiations fail a peer index rollover will eventually occur. As a result, new peers are assigned index values that are already in use and the iked process starts to crash repeatedly. This results in failure to establish new VPN connections and rekeying existing ones. To restore service the system must be rebooted. Please note that the index value can't be monitored, so customers should monitor tunnel up and down events and if a lot of events occur over an extended period of time it becomes likely that this issue occurs. To be exposed to this issue the system needs to run iked (vs. kmd which is not affected), which can be verified with: user@host> show system processes extensive | match "KMD|IKED" This issue affects Junos OS on MX with SPC3, SRX Series: * all versions before 23.2R2-S7, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S3, * 24.4 versions before 24.4R2-S4, * 25.2 versions before 25.2R1-S1.

CVE-2025-59048 (GCVE-0-2025-59048)

Vulnerability from cvelistv5 – Published: 2025-10-23 15:09 – Updated: 2025-10-23 15:40

Title
OpenBao AWS Plugin Vulnerable to Cross-Account IAM Role Impersonation in AWS Auth Method
Summary
OpenBao's AWS Plugin generates AWS access credentials based on IAM policies. Prior to version 0.1.1, the AWS Plugin is vulnerable to cross-account IAM role Impersonation in the AWS auth method. The vulnerability allows an IAM role from an untrusted AWS account to authenticate by impersonating a role with the same name in a trusted account, leading to unauthorized access. This impacts all users of the auth-aws plugin who operate in a multi-account AWS environment where IAM role names may not be unique across accounts. This vulnerability has been patched in version 0.1.1 of the auth-aws plugin. A workaround for this issue involves guaranteeing that IAM role names are unique across all AWS accounts that could potentially interact with your OpenBao environment, and to audit for any duplicate IAM roles.

CVE-2025-13609 (GCVE-0-2025-13609)

Vulnerability from cvelistv5 – Published: 2025-11-24 18:08 – Updated: 2026-06-29 20:29
VLAI
Title
Keylime: keylime: registrar allows identity takeover via duplicate uuid registration
Summary
A vulnerability has been identified in keylime where an attacker can exploit this flaw by registering a new agent using a different Trusted Platform Module (TPM) device but claiming an existing agent's unique identifier (UUID). This action overwrites the legitimate agent's identity, enabling the attacker to impersonate the compromised agent and potentially bypass security controls.

CVE-2023-20100 (GCVE-0-2023-20100)

Title
Cisco IOS XE Software for Wireless LAN Controllers CAPWAP Join Denial of Service Vulnerability
Summary
A vulnerability in the access point (AP) joining process of the Control and Provisioning of Wireless Access Points (CAPWAP) protocol of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to a logic error that occurs when certain conditions are met during the AP joining process. An attacker could exploit this vulnerability by adding an AP that is under their control to the network. The attacker then must ensure that the AP successfully joins an affected wireless controller under certain conditions. Additionally, the attacker would need the ability to restart a valid AP that was previously connected to the controller. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition.
