| Duende.AccessTokenManagement is a set of .NET libraries that manage OAuth and OpenId Connect access tokens. Duende.AccessTokenManagement contains a race condition when requesting access tokens using the client credentials flow. Concurrent requests to obtain an access token using differing protocol parameters can return access tokens obtained with the wrong scope, resource indicator, or other protocol parameters. Such usage is somewhat atypical, and only a small percentage of users are likely to be affected. Duende.AccessTokenManagement can request access tokens using the client credentials flow in several ways. In basic usage, the client credentials flow is configured once and the parameters do not vary. In more advanced situations, requests with varying protocol parameters may be made by calling specific overloads of these methods: `HttpContext.GetClientAccessTokenAsync()` and `IClientCredentialsTokenManagementService.GetAccessTokenAsync()`. There are overloads of both of these methods that accept a `TokenRequestParameters` object that customizes token request parameters. However, concurrent requests with varying `TokenRequestParameters` will result in the same token for all concurrent calls. Most users can simply update the NuGet package to the latest version. Customizations of the `IClientCredentialsTokenCache` that derive from the default implementation (`DistributedClientCredentialsTokenCache`) will require a small code change, as its constructor was changed to add a dependency on the `ITokenRequestSynchronization` service. The synchronization service will need to be injected into the derived class and passed to the base constructor. The impact of this vulnerability depends on how Duende.AccessTokenManagement is used and on the security architecture of the solution. Most users will not be vulnerable to this issue. More advanced users may run into this issue by calling the methods specified above with customized token request parameters. The impact of obtaining an access token with different than intended protocol parameters will vary depending on application logic, security architecture, and the authorization policy of the resource servers. |
| Link Following Local Privilege Escalation Vulnerability in TuneupSvc in Avast Cleanup Premium Version 24.2.16593.17810 on Windows 10 Pro x64 allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via creating a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack. |
| Link Following Local Privilege Escalation Vulnerability in TuneUp Service in AVG TuneUp Version 23.4 (build 15592) on Windows 10 allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via creating a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack. |
| Link Following Local Privilege Escalation Vulnerability in NortonUtilitiesSvc in Norton Utilities Ultimate Version 24.2.16862.6344 on Windows 10 Pro x64 allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via the creation of a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack. |
| A Time-of-check time-of-use (TOCTOU) race condition in the SMM communications buffer could allow a privileged attacker to bypass input validation and perform an out of bounds read or write, potentially resulting in loss of confidentiality, integrity, or availability. |
| A path traversal vulnerability has been reported to affect several product versions. If a local attacker gains a user account, they can then exploit the vulnerability to read the contents of unexpected files or system data.
We have already fixed the vulnerability in the following versions:
Qfinder Pro Mac 7.13.0 and later
Qsync for Mac 5.1.5 and later
QVPN Device Client for Mac 2.2.8 and later |
| An issue was discovered in Alcatel-Lucent ALE NOE deskphones through 86x8_NOE-R300.1.40.12.4180 and SIP deskphones through 86x8_SIP-R200.1.01.10.728. Because of a time-of-check time-of-use vulnerability, an authenticated attacker is able to replace the verified firmware image with malicious firmware during the update process. |
| Wasmtime is a runtime for WebAssembly. Prior to version 38.0.4, 37.0.3, 36.0.3, and 24.0.5, Wasmtime's Rust embedder API contains an unsound interaction where a WebAssembly shared linear memory could be viewed as a type which provides safe access to the host (Rust) to the contents of the linear memory. This is not sound for shared linear memories, which could be modified in parallel, and this could lead to a data race in the host. Patch releases have been issued for all supported versions of Wasmtime, notably: 24.0.5, 36.0.3, 37.0.3, and 38.0.4. These releases reject creation of shared memories via `Memory::new` and shared memories are now excluded from core dumps. As a workaround, eembeddings affected by this issue should use `SharedMemory::new` instead of `Memory::new` to create shared memories. Affected embeddings should also disable core dumps if they are unable to upgrade. Note that core dumps are disabled by default but the wasm threads proposal (and shared memory) is enabled by default. |
| Manager-io/Manager is accounting software. In Manager Desktop and Server versions 25.11.1.3085 and below, a critical vulnerability permits unauthorized access to internal network resources. The flaw lies in the fundamental design of the DNS validation mechanism. A Time-of-Check Time-of-Use (TOCTOU) condition that allows attackers to bypass network isolation and access internal services, cloud metadata endpoints, and protected network segments. The Desktop edition requires no authentication; the Server edition requires only standard authentication. This issue is fixed in version 25.11.1.3086. |
| Agno is a multi-agent framework, runtime and control plane. From 2.0.0 to before 2.2.2, under high concurrency, when session_state is passed to Agent or Team during run or arun calls, a race condition can occur, causing a session_state to be assigned and persisted to the incorrect session. This may result in user data from one session being exposed to another user. This has been patched in version 2.2.2. |
| yt-grabber-tui is a C++ terminal user interface application for downloading YouTube content. yt-grabber-tui version 1.0 contains a Time-of-Check to Time-of-Use (TOCTOU) race condition (CWE-367) in the creation of the default configuration file config.json. In version 1.0, load_json_settings in Settings.hpp checks for the existence of config.json using boost::filesystem::exists and, if the file is missing, calls create_json_settings which writes the JSON configuration with boost::property_tree::write_json. A local attacker with write access to the application’s configuration directory (~/.config/yt-grabber-tui on Linux or the current working directory on Windows) can create a symbolic link between the existence check and the subsequent write so that the write operation follows the symlink and overwrites an attacker-chosen file accessible to the running process. This enables arbitrary file overwrite within the privileges of the application process, which can corrupt files and cause loss of application or user data. If the application is executed with elevated privileges, this could extend to system file corruption. The issue is fixed in version 1.0.1. |
| Time-of-check to time-of-use race condition vulnerability potentially allowed an attacker to use the installed ESET security software to clear the content of an arbitrary file on the file system. |
| Quadient DS-700 iQ devices through 2025-09-30 might have a race condition during the quick clicking of (in order) the Question Mark button, the Help Button, the About button, and the Help Button, leading to a transition out of kiosk mode into local administrative access. NOTE: the reporter indicates that the "behavior was observed sporadically" during "limited time on the client site," making it not "possible to gain more information about the specific kiosk mode crashing issue," and the only conclusion was "there appears to be some form of race condition." Accordingly, there can be doubt that a reproducible cybersecurity vulnerability was identified; sporadic software crashes can also be caused by a hardware fault on a single device (for example, transient RAM errors). The reporter also describes a variety of other issues, including initial access via USB because of the absence of a "lock-pick resistant locking solution for the External Controller PC cabinet," which is not a cybersecurity vulnerability (section 4.1.5 of the CNA Operational Rules). Finally, it is unclear whether the device or OS configuration was inappropriate, given that the risks are typically limited to insider threats within the mail operations room of a large company. |
| A divide-by-zero in VirtIO network device emulation in BitVisor from commit 108df6 (2020-05-20) to commit 480907 (2025-07-06) allows local attackers to cause a denial of service (host hypervisor crash) via a crafted PCI configuration space access. |
| Improper resource shutdown in middle of certain operations on some Solidigm DC Products may allow an attacker to potentially enable denial of service. |
| Software installed and run as a non-privileged user may conduct GPU system calls to read and write freed physical memory from the GPU. |
| go-tuf is a Go implementation of The Update Framework (TUF). The go-tuf client inconsistently traces the delegations. For example, if targets delegate to "A", and to "B", and "B" delegates to "C", then the client should trace the delegations in the order "A" then "B" then "C" but it may incorrectly trace the delegations "B"->"C"->"A". This vulnerability is fixed in 2.0.1. |
| Versa SASE Client for Windows versions released between 7.8.7 and 7.9.4 contain a local privilege escalation vulnerability in the audit log export functionality. The client communicates user-controlled file paths to a privileged service, which performs file system operations without impersonating the requesting user. Due to improper privilege handling and a time-of-check time-of-use race condition combined with symbolic link and mount point manipulation, a local authenticated attacker can coerce the service into deleting arbitrary directories with SYSTEM privileges. This can be exploited to delete protected system folders such as C:\\Config.msi and subsequently achieve execution as NT AUTHORITY\\SYSTEM via MSI rollback techniques. |
| A race condition vulnerability in SimplCommerce at commit 230310c8d7a0408569b292c5a805c459d47a1d8f allows attackers to bypass inventory restrictions by simultaneously submitting purchase requests from multiple accounts for the same product. This can lead to overselling when stock is limited, as the system fails to accurately track inventory under high concurrency, resulting in potential loss and unfulfilled orders. |
| Screen version 5.0.0 and older version 4 releases have a TOCTOU race potentially allowing to send SIGHUP, SIGCONT to privileged processes when installed setuid-root. |
