| CVE-2026-42822 | 1 Microsoft | 2 Azure Local, Azure Resource Manager | 2026-05-18 | 10 Critical |
| Improper authentication in Azure Local Disconnected Operations allows an unauthorized attacker to elevate privileges over a network. | ||||
| CVE-2026-44553 | 2 Open-webui, Openwebui | 2 Open-webui, Open Webui | 2026-05-18 | 8.1 High |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, administrative role changes and user deletions do not iterate SESSION_POOL to disconnect affected sessions. As a result, a user whose admin role has been revoked retains admin privileges within their existing Socket.IO session for as long as they keep the connection alive (via automatic heartbeats). The gap is exclusive to the Socket.IO session cache. This vulnerability is fixed in 0.9.0. | ||||
| CVE-2026-41432 | 2 Newapi, Quantumnous | 2 New Api, New-api | 2026-05-18 | 7.1 High |
| New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to version 0.12.10, a vulnerability exists in the Stripe webhook handler that allows an unauthenticated attacker to forge webhook events and credit arbitrary quota to their account without making any payment. This issue has been patched in version 0.12.10. | ||||
| CVE-2026-44226 | 1 Pyload | 1 Pyload | 2026-05-18 | 5.3 Medium |
| pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, pyload-ng WebUI returns full Python traceback details to clients on unhandled exceptions. Because /web/<path:filename> is reachable without authentication and renders attacker-controlled template names, an unauthenticated user can reliably trigger a server exception (for example by requesting a non-existent template) and receive internal stack traces in the HTTP response. This vulnerability is fixed in 0.5.0b3.dev100. | ||||
| CVE-2025-60889 | 2 Stellar-group, Stellargroup | 2 Hpx, Hpx | 2026-05-18 | 9.8 Critical |
| Insecure deserialization of untrusted input in StellarGroup HPX 1.11.0 under certain conditions may allow attackers to execute arbitrary code or other unspecified impacts. | ||||
| CVE-2026-42249 | 2 Microsoft, Ollama | 2 Windows, Ollama | 2026-05-18 | 9.8 Critical |
| Ollama for Windows contains a Remote Code Execution vulnerability in its update mechanism due to improper handling of attacker‑controlled HTTP response headers. When downloading updates, the application constructs local file paths using values derived from HTTP headers without validation. These values are passed directly to filepath.Join, allowing path traversal sequences (../) to be resolved and enabling files to be written outside the intended update staging directory. An attacker who can influence update responses can exploit this flaw to write arbitrary executables to attacker‑chosen locations accessible to the current user, including the Windows Startup directory. This allows execution of arbitrary executables. Critically, when chained with CVE‑2026‑42248 (Missing Signature Verification for Updates), an attacker can deliver malicious payloads that are written to sensitive locations and executed automatically. Because Ollama for Windows performs silent automatic updates and executes staged binaries without user interaction, this results in automatic and persistent code execution without user awareness. Maintainers of this project were notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Versions from 0.12.10 to 0.17.5 were tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable. | ||||
| CVE-2026-8503 | 1 Guimard | 2 Apache::session::generate::sha256, Apache\ | 2026-05-18 | 6.5 Medium |
| Apache::Session::Generate::SHA256 versions before 1.3.19 for Perl create insecure session ids. Apache::Session::Generate::SHA256 generated session ids insecurely. The default session id generator returns a SHA-256 hash of the built-in rand() function, the epoch time, and the PID, that is hashed again. These are predictable, low-entropy sources. Predicable session ids could allow an attacker to gain access to systems. Note that version 1.3.19 has a fallback without warning to use insecure session generation method if the call to Crypt::URandom::urandom fails. However, this is unlikely as Crypt::URandom is a hardcoded requirement of the module. This issue is similar to CVE-2025-40931 for Apache::Session::Generate::MD5. | ||||
| CVE-2026-42248 | 2 Microsoft, Ollama | 2 Windows, Ollama | 2026-05-18 | 9.8 Critical |
| Ollama for Windows does not perform integrity or authenticity verification of downloaded update executables. Unlike other platforms, the Windows implementation of the update verification routine unconditionally returns success so no digital signature or trust validation is performed before staging or executing update payloads, enabling attacker‑supplied executables to be accepted and later executed by the application. Critically, Ollama for Windows performs silent automatic updates, so the malicious payload may be installed automatically without user awareness. Maintainers of this project were notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Versions from 0.12.10 to 0.17.5 were tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable. | ||||
| CVE-2026-8561 | 4 Apple, Google, Linux and 1 more | 4 Macos, Chrome, Linux Kernel and 1 more | 2026-05-18 | 5.4 Medium |
| Incorrect security UI in Fullscreen in Google Chrome prior to 148.0.7778.168 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium) | ||||
| CVE-2025-10539 | 2 Desktime, Draugiemgroup | 2 Desktime Time Tracking App, Desktime Time Tracking | 2026-05-18 | 4.8 Medium |
| Due to improper TLS certificate validation in the DeskTime Time Tracking App before version 1.3.674, attackers who can position themselves in the network path between the client and the DeskTime update servers can return a malicious executable in response to an update request. This allows the attacker to achieve user-level remote code execution on the affected client. | ||||
| CVE-2026-8562 | 4 Apple, Google, Linux and 1 more | 4 Macos, Chrome, Linux Kernel and 1 more | 2026-05-18 | 4.3 Medium |
| Side-channel information leakage in Navigation in Google Chrome prior to 148.0.7778.168 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium) | ||||
| CVE-2026-6951 | 2 Simple-git Project, Steveukx | 2 Simple-git, Simple-git | 2026-05-18 | 9.8 Critical |
| Versions of the package simple-git before 3.36.0 are vulnerable to Remote Code Execution (RCE) due to an incomplete fix for [CVE-2022-25912](https://security.snyk.io/vuln/SNYK-JS-SIMPLEGIT-3112221) that blocks the -c option but not the equivalent --config form. If untrusted input can reach the options argument passed to simple-git, an attacker may still achieve remote code execution by enabling protocol.ext.allow=always and using an ext:: clone source. | ||||
| CVE-2026-33518 | 3 Esri, Linux, Microsoft | 3 Portal For Arcgis, Linux Kernel, Windows | 2026-05-18 | 9.8 Critical |
| An incorrect privilege assignment vulnerability exists in Esri Portal for ArcGIS 11.5 in Windows and Linux that allows highly privileged users to create developer credentials that may grant more privileges than expected. | ||||
| CVE-2026-33519 | 4 Esri, Kubernetes, Linux and 1 more | 4 Portal For Arcgis, Kubernetes, Linux Kernel and 1 more | 2026-05-18 | 9.8 Critical |
| An incorrect authorization vulnerability exists in Esri Portal for ArcGIS 11.4, 11.5 and 12.0 on Windows, Linux and Kubernetes that did not correctly check permissions assigned to developer credentials. | ||||
| CVE-2026-45667 | 1 Open-webui | 1 Open-webui | 2026-05-18 | 6.5 Medium |
| Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.0, GET /api/v1/memories/ef is accessible without authentication and executes request.app.state.EMBEDDING_FUNCTION(...). This allows any unauthenticated caller to trigger embedding generation which can lead to direct cost exposure if a paid provider is used. This vulnerability is fixed in 0.8.0. | ||||
| CVE-2026-45492 | 1 Microsoft | 1 Edge Chromium | 2026-05-18 | 5.4 Medium |
| Improper input validation in Microsoft Edge (Chromium-based) allows an unauthorized attacker to bypass a security feature over a network. | ||||
| CVE-2026-31431 | 11 Amazon, Arista, Canonical and 8 more | 43 Amazon Linux, Cloudvision Agni, Cloudvision Portal and 40 more | 2026-05-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated data. There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly. | ||||
| CVE-2026-8612 | 1 Oalders | 2 Www::mechanize::cached, Www\ | 2026-05-18 | 5.3 Medium |
| WWW::Mechanize::Cached versions before 2.00 for Perl deserialize cached HTTP responses from a world-writable on-disk cache, enabling local response forgery and code execution. With no explicit cache backend, WWW::Mechanize::Cached constructs a default Cache::FileCache under /tmp/FileCache without overriding the backend's documented directory_umask of 000, so the cache root and its subdirectories are created mode 0777 with no sticky bit. Cache entries are named by sha1_hex of the request and read back through Storable::thaw on the next cache hit. A local attacker with write access to the cache tree can replace a victim's cache entry for a known URL with an arbitrary frozen HTTP::Response blob, causing the victim's next get() of that URL to return attacker controlled response bytes. Because the bytes are passed to Storable::thaw, a victim process that has loaded any class with a side-effectful STORABLE_thaw, DESTROY, or overload hook can be escalated to arbitrary code execution. | ||||
| CVE-2026-2652 | 2 Lfprojects, Mlflow | 2 Mlflow, Mlflow/mlflow | 2026-05-18 | N/A |
| A vulnerability in mlflow/mlflow versions 3.9.0 and earlier allows unauthenticated access to certain FastAPI routes when the server is started with authentication enabled (`--app-name basic-auth`) and served via uvicorn (ASGI). The FastAPI permission middleware only enforces authentication on `/gateway/` routes, leaving other routes such as the Job API (`/ajax-api/3.0/jobs/*`) and the OpenTelemetry trace ingestion API (`/v1/traces`) unprotected. This allows unauthenticated remote attackers to submit jobs, read job results, cancel running jobs, and inject arbitrary trace data into experiments. The issue arises from an architectural mismatch between Flask and FastAPI authentication mechanisms, where the `_find_fastapi_validator()` function fails to handle non-`/gateway/` paths, resulting in a complete authentication bypass. This vulnerability is fixed in version 3.10.0. | ||||
| CVE-2026-41702 | 1 Vmware | 1 Fusion | 2026-05-18 | 7.8 High |
| VMware Fusion contains a TOCTOU (Time-of-check Time-of-use) vulnerability that occurs during an operation performed by a SETUID binary. A malicious actor with local non-administrative user privileges may exploit this vulnerability to escalate privileges to root on the system where Fusion is installed. | ||||
