CVE-2024-38358

Wasmer is a web assembly wasm Runtime supporting WASIX, WASI and Emscripten. If the preopened directory has a symlink pointing outside, WASI programs can traverse the symlink and access host filesystem if the caller sets both oflags::creat and rights::fdwrite. Programs can also crash the runtime ...

CVE-2024-38358

Wasmer (a WASM runtime) is affected by CVE-2024-38358 due to a bug where preopened directories containing a symlink pointing outside can be exploited to traverse the symlink and access the host filesystem if the caller uses both oflags::creat and rights::fd_write. The issue can also crash the run...

Node.js: WASI sandbox escape via symlink

A WASI + WASM program was discovered to be able to use pathsymlink to read arbitrary files on the host machine by creating a symlink in a preopen to a different location on the local file system, thereby escaping the WASI sandbox...

Fastly Compute@Edge JS Runtime has fixed random number seed during compilation
