GHSA-F632-VM87-2M2F qdrant has arbitrary file write via `/logger` endpoint

Summary It is possible to append to arbitrary files via /logger endpoint. Minimal privileges are required read-only access. Tested on Qdrant 1.15.5 Details POST /logger Source code link endpoint accepts an attacker-controlled ondisk.logfile path. There are no authorization checks but authenticati...

GHSA-9FFM-FXG3-XRHH NiceGUI's Path Traversal via Unsanitized FileUpload.name Enables Arbitrary File Write

Summary NiceGUI's FileUpload.name property exposes client-supplied filename metadata without sanitization, enabling path traversal when developers use the pattern UPLOADDIR / file.name. Malicious filenames containing ../ sequences allow attackers to write files outside intended directories, with...

nodejs: Nodejs file permissions bypass

A flaw in Node.js’s Permissions model allows attackers to bypass --allow-fs-read and --allow-fs-write restrictions using crafted relative symlink paths. By chaining directories and symlinks, a script granted access only to the current directory can escape the allowed path and read sensitive files...

Pinger 1.0 contains a remote code execution vulnerability that allows attackers to inject shell commands through the ping and socket parameters. Attackers can exploit the unsanitized input in ping.php to write arbitrary PHP files and execute system commands by appending shell metacharacters...

CVE-2026-25539 SiYuan has Arbitrary File Write via /api/file/copyFile leading to RCE

SiYuan is a personal knowledge management system. Prior to version 3.5.5, the /api/file/copyFile endpoint does not validate the dest parameter, allowing authenticated users to write files to arbitrary locations on the filesystem. This can lead to Remote Code Execution RCE by writing to sensitive...
