CVE-2026-49248 OneDev: RCE through absolute-path symlink following allows low-privileged users to overwrite arbitrary server via TarUtils.untar

OneDev is a Git server with CI/CD, kanban, and packages. In versions 15.0.6 and below, TarUtils.untar creates symbolic links verbatim from TAR entry getLinkName without validating whether the target is an absolute path. A subsequent file entry in the same archive traverses the symlink, writing to...

CVE-2026-49248

OneDev CVE-2026-49248 affects versions 15.0.6 and earlier. TarUtils.untar() creates symbolic links using entry getLinkName() without validating absolute path targets; a following file entry can traverse the symlink and write to arbitrary server-side locations. This enables RCE-like behavior for a...

CVE-2026-47833

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...

CVE-2026-48983

CVE-2026-48983 affects pam_usb prior to version 0.9.2, where a TOCTOU race in per-device and per-user pad directory creation can be exploited via a symlink substitution. pam_usb performs a check-then-act using lstat() followed by mkdir(), allowing a local attacker to replace the target path with ...

CVE-2026-48983

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...

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...
