PYSEC-2026-4173 OpenStack Swift vulnerable to authenticated server-side request forgery

In OpenStack Swift before 2.37.2, proxy-server does not strip internal update headers X-Container-Host, X-Container-Device, X-Delete-At-Host, X-Delete-At-Device from client requests before forwarding them to object-servers. An authenticated user with write access can inject these headers to...

CVE-2026-102673

A flaw was found in Electron. When a popup window is opened from an embedded web frame iframe using navigation actions such as opening a link in a new tab, the popup fails to inherit the frame's sandbox security restrictions. A remote attacker controlling untrusted content within a sandboxed fram...

CVE-2026-96659 Foreman: excessive permissions for viewer role on preview

A flaw was found in Foreman. This vulnerability allows an authenticated user with low-level Viewer permissions to cause unauthorized information disclosure by submitting requests to template preview endpoints. By exploiting this issue, the user can access sensitive data, such as host root...

CVE-2026-63292

A stack-based buffer overflow exists in mod_vhost_alias within the Apache Software Foundation Apache HTTP Server (versions through 2.4.68). An attacker can trigger this by sending an HTTP request with a Host header exceeding 8192 bytes, provided that VirtualDocumentRoot uses a hostname format spe...

GHSA-HF8H-97GM-4X2P SiYuan: getUniqueFilename passes an unvalidated client-supplied path to the filesystem, giving anonymous readers an existence oracle over the entire host filesystem

Summary /api/file/getUniqueFilename takes a path from the request body and passes it to a filesystem existence check with no validation, confinement or authorization. The response distinguishes paths that exist from paths that do not, so an anonymous reader in publish mode can probe arbitrary...

vm2: Incomplete nodejs.* symbol filtering lets sandbox override host WebStream state checks

Summary vm2 current head v3.11.5, commit 7a1f5100b96f48d34e0fe104ab37c0acc5944f92 still exposes registered Node.js internal symbols from host WebStream prototypes to sandbox code. The prior nodejs. symbol hardening blocks Symbol.for'nodejs.' at the source, but the extraction filters and bridge...

vm2 CLI provides no sandbox isolation - host-realm require() is reachable from sandboxed scripts

Summary The vm2 command-line tool installed by npm install -g vm2 and documented in the README's "CLI" section runs the supplied script under NodeVM with require:external:true and no root / context / builtin configured. With these defaults the resolver loads every relative or absolute require...

vm2 exposes host HTTPS credentials and TLS traffic through globalAgent

Summary vm2 3.11.6 exposes the host process's real https.globalAgent when a NodeVM is explicitly allowed to require https. The module is wrapped as read-only, but calls to methods on the shared agent still mutate the host object. Sandbox code can register a free listener and receive host request...

vm2 Custom Module Resolver Can Bypass the External Package Allowlist by Loading a Colliding Host Package

Summary vm2 is a sandbox library for isolating and executing untrusted JavaScript code inside a Node.js process. It can restrict access to built-in modules and external packages. When NodeVM enables an external allowlist together with a custom resolve callback, vm2 checks the requested package na...

GHSA-6RH5-QQ4Q-97XH vm2: NodeVM builtin denylist bypass via fs/promises despite -fs, allowing host filesystem writes

Summary NodeVM's builtin wildcard policy can allow sandboxed code to access fs/promises even when the embedder denies fs. With the following configuration: js require: builtin: '', '-fs', '-childprocess' require'fs' and require'childprocess' are blocked, but require'fs/promises' and...

GHSA-633R-HQ9M-C4FF vm2: vm.freeze()/vm.readonly() bypass via accessor descriptor

Summary Untrusted JavaScript running inside new VM.run / new NodeVM.run can bypass vm.freeze / vm.readonly and mutate a host object the embedder explicitly marked read-only - the documented contract is "prevent sandboxed scripts from adding, changing, or deleting properties". If the frozen host...
