GHSA-3JHR-MXMX-38CX Grav: UserInterface offsetget/offsetexists allow-listed in Twig sandbox let editor-authored content leak hashed_password and 2FA secrets via offsetGet()

Summary system/config/security.yaml's Twig sandbox policy allow-lists offsetget and offsetexists for Grav\Common\User\Interfaces\UserInterface. The concrete Grav\Common\User\DataUser\User class does not filter which fields offsetGet returns, so any sandboxed template with access to a User object...

GHSA-P597-CRQC-M349 Grav: The system, site, and theme Twig variables bypass the content sandbox entirely and are never covered by config_denied_paths

Summary Grav\Common\Twig\Twig::init unconditionally puts the raw system, site, and theme config arrays into $this-twigvars. Twig::processPage builds the variables for the sandboxed, editor-authored page-content render by copying that same base array $sandboxvars = $twigvars; and replacing only th...

RestrictedPython vulnerable to sandbox escape via string.Formatter field resolution

Impact RestrictedPython could allow a sandbox escape when a policy exposes the standard library string module, or otherwise exposes string.Formatter, to restricted code. string.Formatter field resolution methods such as getfield can perform attribute and item traversal internally and return live...

CVE-2026-92949

A flaw was found in vm2, a JavaScript sandbox. This vulnerability allows sandboxed scripts to bypass security protections, specifically vm.freeze and vm.readonly, which are designed to prevent unauthorized modifications to objects. An attacker can exploit this by directly accessing and invoking...

CVE-2026-92958

A flaw was found in vm2, a sandbox for Node.js. When the NodeVM embedder uses a builtin wildcard with negative entries to deny specific modules, such as 'fs' for file system access, the denylist mechanism fails to block subpaths like 'fs/promises'. This allows sandboxed code to bypass the intende...

Critical Docker Sandboxes Flaw Lets Malicious Guest Code Read and Modify macOS Host Files

Malicious code running inside a Docker Sandboxes virtual machine on macOS could escape the project directory shared into it and read or change files anywhere else on the host, Docker warns in a security announcement on September 15. The escape runs with the rights of the host account that runs th...

CVE-2026-92959

A flaw was found in vm2, a JavaScript sandbox. This vulnerability allows a sandboxed script to bypass security restrictions designed to prevent asynchronous code execution. An attacker can exploit this by using specific Promise methods to assimilate malicious 'thenables,' enabling code to run...

CVE-2026-92952

A flaw was found in vm2. The vm2 sandbox incompletely filters Node.js internal symbols, specifically nodejs.stream.disturbed and nodejs.stream.errored, across the sandbox boundary. This allows code running within the sandbox to obtain real host symbols and use them to corrupt the host-visible...

CVE-2026-92960

vm2 before 3.11.6 fails to restrict access to os and dns builtins under the builtin: '' configuration, allowing sandbox code to read host process identity and network topology. Attackers can invoke dns.setServers to hijack the host process DNS resolver globally, redirecting all subsequent host DN...
