CVE-2026-48983 pam_usb: TOCTOU race condition in pad directory creation allows symlink substitution

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, a symlink race condition exists in per-device and per-user pad directory creation. pamusb uses a check-then-act pattern: it calls lstat to test for existence and then calls mkdir separate...

setupBpmLogs follows symlink for bpm.log open and chown — container-to-host privilege escalation via /etc/shadow. A compromised process inside a bpm container can cause root to chown an arbitrary host file to vcap and append bpm JSON log lines to it. The chown alone lets the attacker take ownersh...

GHSA-RVP7-W75Q-9FV2 BBOT: Symlink-Following Arbitrary Write via github_workflows Module

The githubworkflows module constructs local directory paths from user-controlled repository names without validating for symlinks. A local attacker sharing the scan directory can plant a symlink at the predictable output path, causing workflow data to be written to an attacker-chosen location...

GHSA-Q6R4-3WMG-FWCQ Podman: WORKDIR symlink traversal vulnerability

Summary Running a malicous container image where the WORKDIR path contains a symlink can create a directory or modify ownership on the host filesystem. Modified ownership is less likely to happen as that requires help from an untrusted/malicious process that mutates the host filesystem tree durin...

GHSA-3PVJ-JV98-QHJQ Chrome DevTools for agents: daemon.pid write follows symlinks in /tmp fallback runtime directory

Summary The chrome-devtools-mcp daemon writes its PID file with fs.writeFileSync to a deterministic runtime path. On typical macOS environments, and on Linux sessions where $XDGRUNTIMEDIR is unset, that runtime path falls back to /tmp/chrome-devtools-mcp-/daemon.pid. Because the write does not us...
